Rotational Dynamics

Rotational Dynamics Abstract Rotational kinetics is the study of the many angular equivalents that live for transmitter dynamics, and how they relate to one an otherwise. Rotational dynamics lets us view and consider a entirely new treated of physical applications including those that involve rotational motion. The purpose of this investigate is to investigate the rotational concepts of s destructioner dynamics, and study the relationship between the 2 quantities by development an Atwood shape, that contains two divers(prenominal) stooles attached. We use the height (0. Mom) of the Atwood machine, and the average measure (2. 5 s) the heavier eight took to hit the bottom, to face the acceleration (0. 36 m/SAA) of the Atwood machine. Once the acceleration was obtained, we used it to find the angular acceleration or alpha (2. 12 radar/SAA) and moment of run( crookedness) of the Atwood machine, in which so we were eventually fitted to channelise the moment of inertia for the Atwood machine. In compare rotational dynamics and linear dynamics to vector dynamics, it varied in the fact that linear dynamics happens alone in one direction, magic spell rotational dynamics happens in many different directions, while they are two examples of vector dynamics.Laboratory Partners Divine Kraal James Mulligan Robert Goalless Victoria Parr Introduction The experiment deals with the Rotational Dynamics of an object lens or the billhook motion (rotation) of an object around its axis. Vector dynamics, includes some(prenominal) Rotational and Linear dynamics, which studies how the surprises and torques of an object, affect the motion of it. Dynamics is related to Newtons second law of motion, which states that the acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the alike direction as the net force, and inversely proportional to the mass of the object.This is where the famous law of F=ma, for ce equals mass times acceleration, which directly deals with Newtons second law of motion. The important part of Newtons second law and how it relates to rotational dynamics and circular motion, is that Newtons second law of rotation is applied directly towards the Atwood machine, which is Just a different form of Newtons second law. This equation for circular motion is torque=FRR=l(alpha), which is important for helping us extrapolate what forces are acting upon the Atwood machine. It is important to test the formulas because it either refutes or provesNewtons second law of rotation and more importantly helps us excise the moment of inertia and what it really means. Although both rotational and linear dynamics fall under the category of vector dynamics, there is a big difference between the two quantities. Linear dynamics pertains to an object moving in a straight line and contains quantities such as force, mass, displacement, velocity, acceleration and momentum. Rotational dyna mics deals with objects that are rotating or moving in a curved mode and involves the quantities such as torque, moment of inertia, angular velocity, angular acceleration, and angular momentum.In this lab we will be incorporating both of these ideas, but mainly focusing on the rotational dynamics in the Atwood Machine. Every value that we discoer in the experiment is important for finding the moment of inertia for the Atwood machine, which describes the mass property of an object that describes the torque needed for a specific angular acceleration ab bulge an axis of rotation. This value will be discovered by getting the two masses used on the Atwood machine and calculating the clog, then getting the average time it takes for the smaller weight to hit the ground, the height of theAtwood machine, the rundle, the circumference, and the mass of the wheel. From these values, you can calculate the velocity, acceleration, angular acceleration, angular velocity, and torque. Lastly, the l aw of conservation of energy equation is used to find the formulas used to eventually obtain the moment of inertia. Once these values are obtained, it is important to consider the rotational dynamics and how it relates to vector dynamics. It is not only important to look how and why they relate to each other, but to prove or disprove Newtons second law of motion and understand what it means.Purpose The purpose of this experiment is to study the rotational concepts of vector dynamics, and to understand the relationship between them. We will assume the relationships between the two quantities hold to be true, by using an Atwood machine with two different masses attached to discover the moment of inertia for the circular motion. Equipment The equipment used in this experiment is as follows 1 Atwood machine 1 0. 20 kilogram weight 1 0. 25 kilogram weight 1 scale 1 piece of puff 1 stop watch with 0. 01 accuracy Procedure 1 . Gather all of the equipment for the experiment. 2.Measure the weight of the two masses by using the scale, making sure to measure as dead-on(prenominal)ly as possible. 3. Measure the length of the radius of the wheel on the Atwood machine. Then after obtaining this number, double it to obtain the circumference. 4. After measuring what is need, proceed to set up the Atwood machine properly. Ask the TA for assistance if needed. 5. First start by tying the quit of the range to both weights, double knotting to make sure that it is tight. 6. Set the string with the weights attached to the groove of the Atwood machine wheel, making sure that it is properly in place. 7.Then set the lighter mass on the appropriate demise of the machine, and hold in place, so that the starting point is at O degrees. 8. Make sure that the stopwatch is ready to start recording time. 9. When both the timer and the weight dropper are ready to start, exonerate the weight and start the time in sync with one another. 10. At the exact time the mass makes contact with the floor, stop the time as accurately and precise as possible. 1 1 . resound this process three times, so that an average can be obtained of the three run times, making the selective information a much more accurate representation of the time it takes he weight to hit the ground. 2. like a shot that the radius, masses, and time are recorded, it is time to perform the calculations of the data. 13. Calculate the velocity, acceleration, angular acceleration, moment of force or torque, and finally moment of inertia. 14. Finally, compare the relationships of the rotational concepts inquired and draw conclusions. Notes and Observations The Atwood machine contained four outer cylinders that stuck out of the wheel, which cause atmosphere resistance in rotation, and contribute to the moment of inertia. The timer, was hard to stop at the exact right time when the weight made contact with he floor.Lastly, there was friction of the string on the wheel, when the weight was released and it ru bbed on the wheel.

This caused air resistance in which we could not account for. We only measured the weight of the four cylinders for the total weight of the Atwood machine, because the wheel itself was massages in comparison.Even though it accounted for very smaller error in our experiment, it effected the other numbers that we calculated in our data, making them a diminished less accurate. When finding the amount of time it took the heavier weight to make contact with the rubber pad, there was compassionate error in the reaction time of the timer in which we accounted for, making our data more accurate and precise. This is why we averaged all of the values in order to make the times more precise. Lastly, there was error for the friction of the string making contact with the wheel, which we did not account for, because there was no way of account for it.The reason why the force f the tension and the weight were not equal to each other was because of this friction force that existed, which we were not able to find. Conclusion Throughout this experiment we examined the circular dynamics of a pendulum when outside act upon it, making the pendulum move in a circular motion. We measured many values, including the per iod, in order to determine the theoretical and observational forces acting on the pendulum. From this we were able to draw conclusions about how the experimental and theoretical forces relate to each other.We also were able to test Newtons second law of motion find out whether or not t holds to be true. The values that we obtained to get our experimental and theoretical forces started with setting up the cross bar set-up, and attaching the string with the pendulum to the force gauge and obtaining the tension in the string which was 3 Newtons, by reading the off of the gauge, while the pendulum was swinging in a circle. We then measured the mass of the pendulum with a balance scale to be 0. 267 kilograms, which were then able to find the weight to be 2. 63 Newtons.Next we were able to find the length of the string and force gauge attached to the pendulum. Instead of measuring Just the string attached to the pendulum, we also measured the force gauge, because without it our reading s would be inaccurate. After placing the wall grid under the pendulum, we received the numeric value of 0. 5 meters of the radius by reading it off of the chart, by measuring from the origin, to the end of the where the pendulum hovered the graph. Then we found the period by using the stopwatch, which was 1. 71 seconds. We started the time at the beginning of the first crossbar and ended it at the same place.With these numbers that we measured we were able o calculate the angle of the string to the crossbars when it was in motion to be 35. 5 degrees. Then we found the constant velocity by using V = nor/t, in which we obtained the value of 1. 84 meters/second. From this we used the formula a = 2/r to calculate the constant acceleration which was 6. 67 m/SAA, which we came to the understanding that the pendulum was moving very quickly, and that it took a while to muffled down. From this we used Newtons famous second law, which was F=ma, to solve for the Force that was subjected on t he pendulum.We knew that if this value was airily constraining to our experimental value that his theory would be proven correct. Me modified the equation to fit for the situation that was involved, in which we used F = m x 2/r to receive the value of 1. 81 Newtons. Lastly, by using all of the data that we obtained from the experiment, we used the formula Force Experimental= Ft(sin B) to get an experimental force value of 1. 74 Newtons, which lead us to believe we solved for the correct formulas, and followed the procedure for the experiment correctly. round of the discrepancy in our data comes from the instability of the crossbar set- up.This is because our crossbar holders were not in place correctly, which we couldnt correct, so we obtained our data as accurately as we could. Another error in our data came from the force gauge, in that it didnt stand pipe down when we set the pendulum in motion. We couldnt read exactly what was on the force gauge and it also kept ever-changing numbers, so we had to estimate based on what we saw. Lastly, the error in reaction time of the stopwatch changed our data. Without these errors existing, I believe our experimental values would be closer to our theoretical values. Even though this may be true, our values were only different by 0. Newtons, meaning we performed the experiment correctly for the most part. From the results that we obtained from the experiment, we now understand what we would have to do to improve our results in collecting data and obtaining the Experimental Force acting on the pendulum. Our error could have been improved by using a different table with more stability, change our reaction time, and obtaining multiple values for the force gauge then averaging the results. We figured out that even though there was error in our experimentation, that our values were still pretty accurate Judging by the theoretical value.Theoretical values are based on what is discovered by physicists performing the experim ent over and over again. So to use these values and get a number only fractions off, shows that the way we performed our experiment was not very far off. We proved Newtons second law to be true, because by doing the experiment and getting analogous values shows that his concept holds to be true. The forces that we used to move the pendulum showed the dynamics of the pendulum, and how this can be used to understand concepts of the planets rotating around the sun in the universe, Just at a much smaller scale.

Identity Theft: Exaggerated Risk or Real Threat? Essay

IntroductionYou become $92.13c left(p) in your Chase bevel account, contact us today with your details to switch from teleph wizard banking to online banking I was in the country scarce 72 hours and I was already subject to several(prenominal) mavin attempting to steal my individualism I am referring to the past(a) summer that I spent in the States working beneath a student visa. afterwards registering my mobile ph bingle and opening my first American bank account, I started getting texts like the unmatchable above. This my was my first personal exposure to the problem of Identity thieving, and after a quick Google search to wonder what I was dealing with, I found that it was a very common occurrence in America More than 57 million American adults receive phishing attack emails & texts each year from hackers or cyber thieves who get to to be trusted service providers to steal consumer account information, and more than half of those who responded become victims of Ide ntity stealth (Gartner Research, Phishing Attack Victims in all probability Victims for Identity stealing). Lucky I didnt respond to that text then, arent I? That was alone my polished run in with what has become a global problem everywhere the withstand decade.And, the more I delved into the reading for this question, the more I became aware of the vast amounts of literature available to me. I felt none of the other topics for this subsidisation had such in depth reading, which was to the highest degreely available online to me. at that place was online e-books, rough of which I purchased Identity thieving Secrets Ex constitute The Tricks of The softwood By Dale Penn, and Double Trouble by Neal OFarrell. Research websites were to a fault helpful, like the Gartner Research website. I found some very raise websites online, one of which Ill give a point Publications USA an American government run website, it had a air division to provide American consumers with i nformation on Identity theft. Sites like these helped me understand the impact of Identity larceny on the consumer, how the consumer battles it and ultimately this showed me how stemma must deal with it, in their every day transactions with consumers. in that location was a vast amount of Scholar articles I found online, through Google scholar of course, they took very interesting views on the problem, and posed some very good questions. These articles included Did Privacy issues cause indistinguishability theft? to articles such as Identity theft Myths, Methods and the New Law. Also, simply with a quick examine at the papers every Sunday for the past few weeks, I found plenty of significant in them Papers such as the Sunday Business Post, The fiscal Times, The Guardian & The Irish Times.They ever provided me with some affaire to read that was related to identity theft. After reading all this material, I saw both sides of the argument. close do believe Identity theft is a R eal threat to business and consumers alike. I ordain quickly look at how more of a problem this has become, and I provide then superman to some of the major(ip) nerves, and the impact of these field of studys on business. However, there are the those that believe Identity theft is over exaggerated, I will look closely at how researchers collect their entropy for research, and I will also look at the impact of this over-exaggeration within business, how it has sparked some companies within the surety business to come under scrutiny for over-exaggerating the jeopardy of Identity Theft.Why and how do Identity Thieves do it?Cybercrime has surpassed illegal drug trafficking as a crime enterprise Symantec Corporation, 2009 Identity thieves use the Internet as a weapon against idiosyncratic consumers by taking personal and financial information, such as credit card numbers and favorable security numbers, and then using that information to, purchase products or launder money (I dentity thieves have been cognize to purchase cars and homes or even create criminal records under another individuals identity) Overseas Digest, When deplorable Things Happen To your Good hit.Such a scheme can be devastating for an identity theft victim and can create financial be for credit card companies and other commercial entities. agree to Columbus state university research, computer player in general, within the U.S. alone, exceeds $3 billion each year, and in the U.K. exceeds 2.5 billion each year Columbus State University, 2011. These statistics alone show the huge impact of computer fraud and identity theft on the economy and businesses in the world we live in today. It shows what a moneymaking(a) business Identity Theft has become today.Cases of Identity Theft Causing a Real Threat in Business Arguably the most famous racing shell of Identity Theft is that of Frank Abagnale, who was pictured in the 2002 Hollywood blockbuster movie Catch Me if You Can DreamWorks ( film), 2002. In the 1960s, Abagnale eluded authorities by posing as characters such as an airline pilot, doctor, assistant Attorney General, and history professor, all the while single-foot up $4 million in bad cheques Posing Facts, 10 bizarre cases of Identity Theft. This bizarre case of Identity theft is portrayed in a comical sense in the film, with Tom Hanks left chasing shadows. provided for businesses in todays society it is furthest from comical, as the protection of consumers information poses major issues within business today. The best way to see the affects of Identity Theft on business is to rattling take a look at some of the major cases within the last few years. This will show the business issues and the implications it is having on business on a daily basis.The headlines within the last few years have highlighted the threat that Identity Theft poses. In what was dubbed at the time the volumedst ever case of identity theft to be prosecuted by the American Departm ent of Justice CBS News, 23rd Feb 2010, the Miami Hack ram (dubbed that by Miami New Times, May 20th 2010) stole over 100 million credit observance details over the course of 4 years. The credit card details, which they hacked, were stored by a number of companies one of which was T.J. Maxx, a British retailer (they would be kn make here in Ireland for their chain of stores called T.K. Maxx).The hackers gained access to the ships companionship systems of T.J. Maxx and stole personal information of over 45 million credit card and debit tease in July 2005. These cards be foresightfuled to the companys customers who purchased items from January 2003 to November 23, 2003, save the company did not discover the theft until much later in 2007 Identity Theft Awareness, 2011. Deepak Taneja, chief executive of Aveska, a firm that advised the company on information security commented at the time Its not clear when information was deleted, its not clear who had access to what, and its not clear whether the data kept in all these files was encrypted, so its very hard to know how big this was, St. Petersberg Times, 30th litigate 2007 This quote shows the issues TJ Maxx faced at the time.They simply didnt know how large this was, added to this was the fact that it took nearly 2 years to find the breach. A combination of the above led to huge consumer outrage at the way T.J. Maxx handled their customers information, and left consumers baffled as to why T.J. Maxx held onto the details for 2 years after the transactions had taken place. Many experts speculated that TJ Maxx would pay in a heartfelt way for the incident. Customers would abandon the brand for fear their personal information would be exposed, and investors would avoid the brand because of crippling fines and costs faced by the company. However, in the 12 months that followed the announcement of the breach, TJ Maxx never looked better.Revenues increased Profits increased, and share equipment casualty incre ased Neal OFarrell, Double Trouble 12 Reasons why were Losing the employment against Identity Theft. But what does this rigorous? Could this have been contrived as a clear message to TJ Maxx and other businesses that not totally is a data breach no big deal any more, but it may skilful be another acceptable cost of doing business? Perhaps. But there is still no wondering(a) the potential impact of a companys consumer information being breached.And, in the case of TJ Maxx, if the decently procedures were followed, this kind of occurrence may have been preventable. Despite the fact their Brand and profits didnt suffer, TJ Maxx accomplished this was a major wake up call. And it was still a learning curve for any business looking in. Lessons must be learnt 1) Collect only the minimum personal customer information required to complete a business transaction. 2) Retain the collected personal information for only as long as needed per business and legal requirements. 3) Monitor sys tems to detect unauthorized software and suspicious net income traffic such as unusual data subjectload in terms of size and time. Identity Theft Awareness, 2011.Businesses must constantly consider their risks and assess their internal controls to prevent costly incidents and their unintended consequences. As far as TJ Maxx, the company spent over $130 million to deal with the consequences of this international identity theft case. Even though their Brand didnt seem to suffer, and profits rose and investment wasnt hindered, TJ Maxx couldnt afford to take this risk again. Neal OFarrell, Double troubleThe second case Ill look at is that of Sonys PlayStation Network hack earlier this year. The details of 77 million of Sonys online PlayStation Network customers were breached. This most recent major intrusion has shown that Identity Theft is still a major issue for large corporations. This case again raised major questions about online transactions The Guardian, April 2011. Confidence in E-Commerce has always been a major problem for business OECD Reinforcing consumer confidence- keystone to Boosting e-commerce, it has been for years, after all, its the reason that most think doubly forward making an online purchase, its that lingering feeling that overshadows an online purchase.It is an obstacle that is being slowly removed, but correct backs like this do not help, as Steve Curran, creative director at the Brighton-based studio Zoe Mode, told Develop pickup From my perspective, the bigger issue is not about the PlayStation Network, but confidence in digital distribution generally. For every story like this that breaks in the mainstream press, consumer confidence about their details being safe is eroded. Confidence in online transactions has been make up, and I think will continue to, but this is a blip. It could be a little criterion back Develop Magazine, Digital distrust could follow, 2011. This hack was a major set back for the companys on going battle for control of the gaming market with Microsofts Xbox. And it was up to Sony to construct confidence in their brand after the major breach The Guardian, April, 2011.Is it an Exaggerated Risk?One thing I did notice when I was doing my research was that, most of the information we have on cyber crime losings is derived from surveys. But can one form an accurate estimate by survey alone? J. Ryan & T. Jefferson take up in their book The Use, Misuse, and Abuse of Statistics in Information Technology, that losses are extremely concentrated, so that representative sampling of the population does not give representative sampling of the losses as a whole. They also argue that losses are based on unverified self-reported numbers. Not only is it likely for a single outlier to distort the result, we find evidence that most surveys are dominated by a minority of responses in the upper tail J. Ryan and T. I. Jefferson The Use, Misuse, and Abuse of Statistics in Information Security Research. I n the 1983 federal official Reserve Survey of Consumer Finances an incorrectly recorded answer from a single individual erroneously in inflated the estimate of US household wealth by $1 trillion.This single erroneous belief added 10% to the total estimate of US household wealth Dinei Florencio & Cormac Herley, Microsoft research Sex, Lies and Cyber-Crime Surveys. In the 2006 Federal Trade Commission (FTC) survey of Identity Theft the answers of two respondents were discarded as not being identity theft and inconsistent with the record. Inclusion of both answers would have increased the estimate by $37.3 billion, in other words it would have turnd the estimate 3 fold Federal Trade Commission, 2007. In surveys of sexual behavior men consistently report having had more female sex partners than women report having had male sex partners (which is impossible). The disparity ranges from a factor of 3 to 9. It is pointed out that a tiny portion of men who claim, e.g., 100 or 200 lifeti me partners account for most of the difference.Removing the outliers all but eliminates the discrepancy Florencio & Herley, Microsoft Research. These seem like bare(a) mistakes, which could be avoided, however safeguards against producing these erroneous results seem largely ignored when it comes to Cyber-Crime surveys Florencio & Herley. So, what does this potential over exaggeration mean for business? This over exaggeration and bad estimates can have huge consequences on both preference allocation and in constitution issues within business and government alike. Imagine this, in a simple scenario a research company comes out with staggering new figures about the rise in Identity theft, online fraud, and the number of companies being sued by customers who were affected by their bad data protection protocols. This type of scenario has happened forwards take for example the research conducted by the ITRC (Identity Theft Resource Center) in 2008.They reported that Data Breaches so ared by 47% over 2007 ITRC, 2008 Data Breach Totals Soars. These kind of estimates can cause alarm bells to ring for some businesses, they in turn may pump more funds into the data protection systems in their own firm to prevent what they believed were Real Threats. Yet, as highlighted above there could be major issues with these statistics, and Florencio & Herley even mention the discrepancies of the ITRC yearly surveys in their book.Again, imagine the implications of such research on policy issues, especially government policy issues. If the government take the results of a certain survey on Identity Theft as a perceived Real Threat, and adopt major measures to tackle it, it could have major implications on business. For starters, it could maltreat consumer confidence in E-Commerce. Like I mentioned before, its the reason we all think twice before making a purchase online and isnt it the reason for the introduction of Prepaid Credit learning abilitys? mickle who have never expe rienced Identity Theft take measures to avoid it. And this could be all down to policy measures.Exaggerated Risk on business in the industryOn 29th defect 2011, CPP Group PLC, a British based company selling life assistance products, announced that the pecuniary Services Authority (FSA) would be launching an investigation into the sale of one of its products to U.K. customers. The product included operate such as credit-score monitoring, an Internet search facility wakefulness the user of inappropriate use of their data and a caseworker to help the person reinstate their identity The York Press, 30th March 2011. The financial operate Authoritys investigation centres around allegations that CPP overstated the risk of identity theft when selling insurance policy for that purpose. As a result in the investigation, CPP had to suspend all sales of its identity theft protection product with immediate effect. The product includes services such as credit-score monitoring, an Internet search facility alerting the user of inappropriate use of their data and a caseworker to help the person reinstate their identity.And, after announcing the news to the London stock exchange, shares in CPP fell a staggering 46% from 2.35 to 1.50, within one day of trading Financial Times, March 2011. The reason for this dramatic fall was, as Chief Executive Eric Woolley stated, Card and identity protection products in the U.K. accounted for more than 60 per cent of CPPs business Eric Woolley, March 2011. This shows how exaggerating the risk of Identity theft within this type of organisation can cause massive losses for a business. In one fowl swoop CPP Croup PLC lost almost half its market capitalisation, just because they were under investigation for over stating (A.K.A Exaggerating) the risk of Identity theft through calls to potential customers. This example shows that some can, and do, overstate the risk of Identity theft, and they reap the rewards as a result, as they can sell t he engineering science to tackle it.ConclusionIn the introduction I provided an overview of some of the literature and then within the assignment I took a look at both sides of the argument. Through the major cases above I have shown how Identity Theft is a Real Threat to business. However it is also a threat to small businesses, small businesses must follow the same guidelines as highlighted in the TJ Maxx instance. Failure to could possibly lead to the damaging effects of major fines, lawsuits and the damaging of the brand image of a company, as well as deterring investors. fagt forget the wider implications for business, with the growing trend towards e-commerce, many companies want to take advantage of this, however major data breaches as seen above can hamper the consumer confidence and set back this industry. Again this is a threat to business in this area.Is Identity theft over-exaggerated? You may think I strayed from the point a little here, but I felt it was important t o look at this side of the argument, and what drives it. What mainly drives it is that saddle horse of the argument that the surveys conducted are unreliable. I am personally not over awed by this argument, however the people who make the argument point to some interesting evidence of the inaccuracy of surveys from some top researchers in Identity Theft. A look into the CPP Group case gives another side to the exaggerated risk argument. Do people/corporations over-exaggerate the risk for their own benefit? Perhaps. But that is where regulation steps in, and in the case of CPP they had to change their marketing strategy within a few weeks once the FSA began an investigation. Overall, this was a very interesting topic to research, and it opened my eyes to some new areas of IT within business and some of the problems it must tackle.Bibliography1.Gartner Research, Phishing Attack Victims Likely Targets for Identity Theft, 4th May 2004 (http//www.social-engineer.org/wiki/archives/IdThei f/IdTheif-phishing_attack.pdf)2.Symantec Corporation Cyber Crime has Surpassed Illegal Drug Trafficking as a Criminal Money-maker 1 in 5 will become a Victim Sept tenth 2009 (http//www.symantec.com/about/news/release/article.jsp?prid=20090910_01)3.Overseas Digest Identity Theft When Bad things Happen to your Good Name.
