Torque physics lab report Essay Example

Torque physics lab report Essay Example Torque physics lab report Paper Torque physics lab report Paper The purpose of this experiment was to help understand torque by not only measuring it but also by manipulating and adjusting the weights experimentally. Procedure In order to perform all the procedures a few instruments were required a meter stick, a triple beam balance, suspension clamps and their stirrups, a knife edge, as well as weights of 50 and 100 grams and a spring scale. The meter stick was weighed (without the clamp), and its center of gravity was found (its not usually exactly at 50cm), the 6 clamps were weighed as well. For the first part the meter stick was put on 35cm and a 100g weight was adjusted until the center of balance was found, the position was recorded, this was than done with 150g and 50g. Once the values were recorded the weight of the bar was calculated and the average was found. For the next part of the experiment three weights were attached anywhere on the bar, the center one was adjusted till there was equilibrium and than the force was measured with a spring scale. The numbers were recorded and the weights of down and upward forces were measured as well as the clockwise and counter clockwise torques. For the last part of the experiment six clamps were arranged on the bar( with weights on them ) so that one was at 10cm and one at 90cm and the rest were spread in between , one end was supported by the knife edge and the other by the spring scale. The forced shown by the scale was recorded, the ends were than switched and the force was once again recorded. Calculations were than done to verify the sum of the torque was that of the reading on the spring scale as well as that the total sum of the weights was compared via calculation to the upward force shown. Data/Analysis Part I: Prep Part II: Calculating the weight of the meter bar by balancing torque (mb): (mc= mass of clamp, g = acceleration due to gravity) Table 1: Determination of Meter Weight by Balancing to Torque (Experimental) m= mass of weights (g) x= Clamp Position from knife edge (cm) mb= Weight of Meter Bar from Balancing Torque (g) Position on meter stick (cm) r= position from axis of rotation (m) (N*m)96 Questions: The motion of the rigid system will move up in the counter clockwise direction if the condition for equilibrium is not satisfied in which the spring has greater force. The opposite will happen if the meter bar and weights have a greater force than the spring. The same goes for the Torque. If the second condition for equilibrium is not satisfied and there is greater torque of the spring, the system will move in the counter clockwise motion and will move clockwise if the Torque is greater for the meter bar. The motion of the rigid system will move in the same fashion as described above if neither of the conditions for equilibrium are satisfied. If there are equal numbers of suspension clamps on each side of the support with the same weight, their weights can be omitted from the calculations because the weights can be factored out and be eliminated from the way the force and torque equations are set-up. Regardless, they should total to zero. When the center of gravity of the meter bar was determined in Part I, the bar was supported at a point coinciding with the center of gravity. If the clamp were to have been inverted, where the bar is supported at a point above the center of gravity, you wouldnt een be able to balance the meter bar because it is not in the center of gravity it would just be slack and hang down. Therefore you wouldnt even find the accurate position where it is level. This would have skewed the results, making inaccurate readings and calculations. In part IV, if the meter bar were to be held at an incline of 30 degrees angle above the horizontal by the spring balance, the spring balance reading would remain the same because the force of the spring is just m*g, which remains the same even if you change the angle. The mass and acceleration due to gravity remains constant. However, Torque changes (t=r(F*sin(? )) since angle comes into account. Figure: Conclusion In the study of this lab, torque was observed by measuring, manipulating, and adjusting the weights on the meter bar. The weight of the meter bar was found by experimentally calculating the torque. Comparing the actual weight of the meter bar and the experimental values, the percent error was only 5. 96%-14. %. This percent error is low enough to be negligible and to confirm the equation used for Part II. In Part III and IV, the forces acting on the meter stick are in the vertical direction. Since the meter stick was level, the angle was 180 degrees meaning the force acted on the axis on either side of the center of balance. The experiment should have observed that the net force and net torque acting on the meter stick is equaled to zero. However, experimental results show that the net force is not zero. The net torque is not zero as well. However, the net torque value approaches zero more than the experimental values do. Therefore, the torque equation may be confirmed in this experiment, but the force equation cannot because the values are too far from zero. This may be because the presence of error in this lab is high. Errors occurred in this lab are due to inaccurate measurements of position. It was difficult to keep the meter bar steady to find where the stick is level. Also, there may have been something wrong with the balance and springs because they are very old, rusted equipment and may not work as accurately as they did when they were new. Overall, we were able to understand the concept of torque, even if there were errors in our experiment.

Young Goodman Brown Goodman Brown Essays - Abrahamic Religions

Young Goodman Brown Goodman Brown Essays - Abrahamic Religions Young Goodman Brown Goodman Brown Young Goodman Brown is a moral story that is told through the perversion of a religious leader. In Young Goodman Brown, Goodman Brown is a Puritan minister who lets his excessive pride in himself interfere with his relations with the community after he meets with the devil, and causes him to live the life of an exile in his own community. Young Goodman Brown begins when Faith, Brown's wife, asks him not to go on an errand. Goodman Brown says to his love and (my) Faith that this one night I must tarry away from thee. When he says his love and his Faith, he is talking to his wife, but he is also talking to his faith to God. He is venturing into the woods to meet with the Devil, and by doing so, he leaves his unquestionable faith in God with his wife. He resolves that he will cling to her skirts and follow her to Heaven. This is an example of the excessive pride because he feels that he can sin and meet with the Devil because of this promise that he made to himself. There is a tremendous irony to this promise because when Goodman Brown comes back at dawn; he can no longer look at his wife with the same faith he had before. When Goodman Brown finally meets with the Devil, he declares that the reason he was late was because Faith kept me back awhile. This statement has a double meaning because his wife physically prevented him from being on time for his meeting with the devil, but his faith to God psychologically delayed his meeting with the devil. The Devil had with him a staff that bore the likeness of a great black snake. The staff which looked like a snake is a reference to the snake in the story of Adam and Eve. The snake led Adam and Eve to their destruction by leading them to the Tree of Knowledge. The Adam and Eve story is similar to Goodman Brown in that they are both seeking unfathomable amounts of knowledge. Once Adam and Eve ate from the Tree of Knowledge they were expelled from their paradise. The Devil's staff eventually leads Goodman Brown to the Devil's ceremony which destroys Goodman Brown's faith in his fellow man, therefore expelling him from his utopia. Goodman Brown almost immediately declares that he kept his meeting with the Devil and no longer wishes to continue on his errand with the Devil. He says that he comes from a race of honest men and good Christians and that his father had never gone on this errand and nor will he. The Devil is quick to point out however that he was with his father and grandfather when they were flogging a woman or burning an Indian village, respectively. These acts are ironic in that they were bad deeds done in the name of good, and it shows that he does not come from good Christians. When Goodman Brown's first excuse not to carry on with the errand proves to be unconvincing, he says he can't go because of his wife, Faith. And because of her, he can not carry out the errand any further. At this point the Devil agrees with him and tells him to turn back to prevent that Faith should come to any harm like the old woman in front of them on the path. Ironically, Goodman Brown's faith is harmed because the woman on the path is the woman who taught him his catechism in youth, and was still his moral and spiritual adviser. The Devil and the woman talk and afterward, Brown continues to walk on with the Devil in the disbelief of what he had just witnessed. Ironically, he blames the woman for consorting with the Devil but his own pride stops him from realizing that his faults are the same as the woman's. Brown again decides that he will no longer to continue on his errand and rationalizes that just because his teacher was not going to heaven, why should he quit my dear Faith, and go after her. At this, the Devil tosses Goodman Brown his staff (which will lead

Real Talk Is grad school worth it

Real Talk Is grad school worth it It comes with a high price tag and time commitment, but lots of jobs seem to want a degree beyond a bachelor’s or associate’s. So, is grad school worth it? According to the Bureau of Labor Statistics, the simple answer is yes. Those with doctoral degrees, professional degrees, or master’s degrees have higher median usual weekly earnings and lower unemployment rates. While there are counterpoints to this idea (like Bill Gates, Steve Jobs, or Oprah, who made their wild successes without obtaining any degrees in higher education) and data showing that an electrician or plumbing apprenticeship may be a better investment than either a B.A. or a Ph.D., generally speaking the higher degree of learning you have, the higher your weekly income.But this is all in the abstract- and your real-life situation may not appear so simple as a bar chart. What about the tuition costs, the investment of your time and effort, the job opportunities and earning years you give up in the m eantime, and the possibility that it might not work out the way you want?The question most people need to ask first is: can I afford the short-term pain for the potential long-term gain? There are also differences in every industry and every degree program- some, like a medical degree, will get you a monetary return on investment sooner than an MFA in painting. Earnings vary by industry, demographics, and location, and of course by individual, and a graduate degree does not automatically line your pockets with more cash each week. (In the short-term, it will do the exact opposite.) Degrees also gain and lose earning potential over time; going to law school was a much better bet in the year 2000, before natural learning search algorithms eliminated much of the entry-level work, than it is today. You may also consider other factors like the value the graduate degree has beyond earning potential.But no matter what type of degree you seek, it is work and it is a gamble. So here are a fe w factors to consider before you fill out your FAFSA and brush up on your math skills for the GRE.If you are currently employed and the company will pay for it:Take advantage of professional advancement programs within your current job. If your employer helps pay for grad school and you can juggle courses and your day job, then go for it. This helps take care of one of the main drawbacks of graduate school: going broke. Depending on the degree program, universities might even offer stipends and assistantships.Getting funding assistance of any kind is one of the key bonuses that can help you get that degree to take you further in your professional endeavors. And, if you can remain gainfully employed while seeking a degree, your personal risk is considerably diminished. At the very least, you won’t need to find a new job if the degree program does not pan out.If you consider your qualifications for future positions:For some positions, you simply need a graduate degree. Libraria n? Yes. Architect? Yes. Doctor? Yes. If the dream job you always see posted on your favorite job website requires a graduate degree, then it’s time to seriously consider investing in that future to make the dream achievable. The trickiness of the situation comes when you make yourself overqualified for other positions. For example, if you have a graduate degree in marketing, but have no job experience, you may be screened out of the applicant pool for entry-level jobs. In cases like this, it is vital to explore internship opportunities while in school and cultivate real-world work experience too.If the degree has value beyond earning potential:If you simply have a love of learning or a passion you want to follow, is it worth it? This is the case where â€Å"worth† may be defined beyond the monetary value. This means you will enjoy grad school with its challenges, but you may set yourself back monetarily for a few years. If you want a degree in art history, thereâ€℠¢s no guarantee you will ever get a job as a museum conservator. You may still end up with a sales job and a vast knowledge of 16th century painters in your head.Beyond personal enrichment, there are other types of value for a graduate degree- for example, if the program offers good connections and internships. This can help with careers that are harder to break into like television, acting, or journalism.If you consider the money now vs. money in the future:Degrees with more immediate pipelines to job opportunities (like nursing, law school, or an MBA program) tend to charge tuition; artist’s MFA degrees or a PhD in academic subjects that are less market-oriented tend to offer tuition remission, stipends, assistantships or on-campus jobs. (If they don’t, then it’s much less worth it; don’t go into debt for a nonprofessional graduate degree!) If you’re not in a professional degree program, the lean years may extend a bit longer beyond grad school, and you may only gain success years later as you work towards your goal around your day job.If you are considering using the degree to teach at the college level:The job market for professors has stagnated over the last decade, with a severe glut of degree holders and a dearth of jobs teaching full-time in university departments. Increasingly those earning a PhD in programs of study that can last 5-10 years are seeking out â€Å"alt-ac† jobs- meaning nonacademic jobs- or spending years doing low-wage, low-security teaching work before leaving the profession. Do the research on your field and its job prospects before you commit to spending so many of your prime earning years in graduate school for a teaching career that might never materialize, no matter how smart you are or hard you try.

China Is Going to Become the Next Superpower Assignment

China Is Going to Become the Next Superpower - Assignment Example Before embarking a discussion specifically in a China-centric context, it will be really pragmatic to delineate the salient characteristics of a superpowerFirst and foremost, a superpower always has a robust and stable economy that is sufficient enough to churn out the resources for its fast-expanding ambitions. A superpower is also backed by a strong army, navy and air force that could well do the job of projecting it as a power throughout the world. A superpower also needs to have a strong and well-developed culture that is worthy of extending the requisite philosophical and ideological influences, that well demark and define the approach and strategy of that superpower. Geography can certainly play role in consolidating and encouraging the superpower status of a country, as it did in the case of the erstwhile USSR and the USA. A country that has a vast sea and land area under its control is mostly not only endowed with abundant and rich natural resources but does also enjoy a dist inct tactical advantage in the case of a war. If one takes into consideration the contemporary economic and military power of China and the other related attributes like culture, geography and the like, no doubt China qualifies to be an ideal candidate for becoming the superpower of the future (Mahtaney 7).  Also, not only the Chinese goods are flooding the Western markets, but rather China has emerged as a manufacturing hub for the entire world. China also has embarked on an ambitious plan to modernize its military. It goes without saying that in the recent times, China’s sway in the world affairs has increased over time and China is doing its best to gain a strategic edge not only over its rivals in Asia but also over the Western powers (Mahtaney 4). All these facts constitute a good reason as to why China is poised to achieve a superpower status in the future. China’s Economy In the last three decades, China’s economic growth has been quietly impressive and the nation does seem to have the potential to sustain this growth in the times to come. Simply speaking, China has one big population that not only serves the purpose of creating a big and lucrative domestic market but also extends to China ready access to cost-effective and affordable labor. Not to mention that China is a country endowed with ample natural resources and big sea and land area, which further contribute to and facilitate its economic growth. It was Deng Xiaoping who introduced economic reforms in China in the late 70s. Since the introduction of these reforms, the Chinese economy has developed spectacularly. In the period 1979-1993, the Gross Domestic Product (GDP) of China registered an average growth rate of 9.3 percent (Cass, Williams & Barker 91). It was indeed a great achievement, going by the fact that in the same time period, the average growth rate of the entire world stood at 2.6 percent (Cass, Williams & Barker 91).

Starting a Business Online - Assignment Example It is in this context that reselling of domain names to third parties, as mentioned in the case, is likely to increase the chances of fraudulent and miscommunication in the business process further leading to customer dissatisfaction. This can be considered as a legality constraint while selling a domain name (Clayton & Moore, 2011). In the referred case, the domain name of the organization can be identified playing a vital role to provide a professional appearance in the online business which can be more viable for the enterprise in its future conducts. However, the domain names also transmit some disputes along with it. For instance, the selling of domain names are often identified to increase the risks of subjectivity in terms that the future prospects of generating significant cash flows in future can raise confusions in calculating its proper valuation (Investopedia, 2012). Therefore, considering the future chances of generating larger cash flows and other constraints in terms o f subjectivity and legality, it would be a better decision not to sell the domain name at the quoted price. Answer 2 The catalog display in the e-commerce involve with the facilities to display the products or the features of providing services with regards to online sales. The concept of e-commerce entails with the visual communication about various products/services along with the different varieties, ingredients, and pricing options to the customers. The catalog display of e-business is one of the major tools which communicates and provides browsing options in order to assist the user in acquiring the desired products/services presenting additional and comprehensive information concerning promotional offers (Chopra, n.d.). Similarly, the shopping cart is also regarded as one of the major facets in the e-commerce business model. It assists the customers to maintain a track of the products purchased of those which have been selected for purchased through the electronic shopping car ts. It further allows the customers to check and recheck their purchases adding new items in the cart as well as, if wished, removing any products while making their ultimate purchases. This in turn can assist the organization to build up a productive relationship with its targeted customer group (King Fahd University of Petroleum & Minerals, n.d.). Furthermore, the business transaction processing signifies the set of practice or actions of performed through online or e-commerce software. It is often regarded to act as a system which is performed as a base for other allied operations in the online e-commerce system and thus play a vital role in serving the customers in a better way. As customers are able to obtain superior quality assistance from the marketer through online sites owing to the virtues of transaction processing, organizational are also benefited in terms of enhanced customer satisfaction and loyalty (Becherer & Halstead, 2004). Answer 3 In this present competitive sce nario, the online business entrepreneurs must need to look after various criteria to facilitate the customers rendering them ease in accessing the site. Therefore, building the online website as per the customers’ convenience is one of the crucial factors to accumulate and sustain in the current competitive e-commerce portfolio. The initial step of instigating an e-business model is the registration of a special domain which should reflect the registered name of the organization. The next step

Triangle Solutions Essay Example | Topics and Well Written Essays - 500 words

Triangle Solutions - Essay Example (Brain, 2011) Triangle Solutions would design this park as such that it would be entertaining for both, the adults and children. The amusement park would be designed on the concept of â€Å"Lord of the Rings†. As amusement parks already exist on the concept of Disney and Harry Potter, other successful stories like â€Å"Lord of the Rings†, should also be given due attention, in the form of an amusement park. â€Å"Lord of the Rings† being a successful story and a trilogy of movies is very well-known by all and it has fans amounting to that of Star Wars and Harry Potter. The plan of the park would be based on the map of places mentioned in Lord of the Rings. The Amusement Park would welcome its customers with the â€Å"Shire†, the luscious green mountains and valleys where the main character Frodo Baggins lived. This place would include going through Frodo’s house, and the small pubs and houses present in the valley. Here, the journey of the Shire would end. Not to mention, that characters like Frodo Baggins, Bilbo Baggins, Gandalf the Grey, Peregrin Took, and Meriadoc Brandybuck would be present too, to give a feel of the Shire. Next would be the Elven forest of Lothlà ³rien, where the Lady Galadriel who took care of Frodo and bestowed him with gifts would be present to welcome the customers. The Fangorn Forest, where Frodo meets the giant talking trees the Ents, would be the next stop to give the park a more adventurous feel, with characters dressed up as these trees. Then the customers would move on to Helm’s Deep, the dark place underground where Sauron’s Orcs would surprise the customers as they surprised the character Frodo Then the city of Minas Tirith would loom in front of the people, the city which was situated on mountainous terraces, and was attacked by Sauron’s forces. Its majestic white towers would be there to welcome the customers as
