Torsion Lab Report Example | Topics and Well Written Essays - 1500 words

Torsion - Lab Report Example Fenner and other (1984) indicated that the modulus of rigidity is given by the ratio of stress to shear strain often represented mathematically as ?/?. As widely cited, modulus of rigidity is essential in measuring the material’s shear stiffness and it is known to be analogous to Young’s modulus for any elastic behaviour in compression or tension (Benham, Crawford & Armstrong, 1996). Given that a ductile material component useful in providing shear, an individual need to note that the maximum shear stress is safety, which is less than the materials yield shear stress (?y). However, a brittle material the criterion of failure is based upon its tensile stress (Gere &Timoshenko, 1984). Research indicate that the theory of torsion often give the torque in form of rotation as (1) The equation 1 above is often derived from Hooke’s law and it is also valid for the shear stresses though somewhat lower than shearing proportional limit (Case, Chilver & Ross, 1993). In a so lid circular section, it has been outlined mathematically that the polar second moment of the area of cross section is given by equation (2) (Ryder, 1969) (2) This implies that from (1), it can be shown that the maximum shear stress, that occurs at r = d/2, is provided by equation (3) (3) This experiment deals with determining yield shear stress along with the modulus of rigidity for the specimen of brass and mild steel of a circular cross section. Apparatus In this experimental set up, there were various sets of apparatus used. Among them were the torsion machine, a torsion bar, a gearbox, a torque meter, two protractors, a counter, and a hand-wheel. This way, a torsion machine was used for carrying out a test involving a specimen that was accommodated within the socket at each end. The 60:1 reduction gearbox served the purpose of manually applying the angular displacement at the left- hand side. The torsion bar was essential in this experiment given that it was used for measuring the torque when at right-side with a torque meter being used for reading digital data. The two protractors listed above were vital in this experiment since they were used for purposes of measuring the rotation of the specimen. They were placed at the gearbox, in which case, one was placed at the input hand wheel along side a 6 degrees scale, while the second gearbox was placed at the specimen shaft at 360 degrees scale. The counter, on the other hand, was used in providing the number of revolutions each of which might be zeroed. Last but not least, the hand-wheel placed at the torque meter assembly was used in returning the right-hand of the given specimen back to the original position. Procedure It is worth enlisting that this lab exercise involved 2 experiments: experiment 1 and experiment 2. This implies that there were specific procedures for specific experimental set up. In experiment 1, which involved determining the modulus of rigidity G for brass and mild steel, the procedur e for the experiment involved the following steps. 1. The diameter of the each of the cylindrical portion of the specimen was measured. 2. Using the level, the torque meter hand-wheel was adjusted in ensuring that the torsion bar, as well as the deflection bar is maintained close to and as parallel as possible. 3. The dial gauge was then set to zero through rotating the outer bezel. 4. The specimen was then accommodated in the right hand hexagonal

Thesis Requirements Essay Example | Topics and Well Written Essays - 2500 words

Thesis Requirements - Essay Example Thesis Requirements A thesis also must have an explanation of the methodology – how was the information gathered to answer the research questions, how many participants, and what is the theory behind the methods? Another section which is a part of a thesis requirements is the research findings, which explain what the data was, and interprets the data so that the research questions are answered. Conclusions and recommendations are another necessary section, in which the thesis is explained in a nutshell, and the recommendations are areas for further study, as well as recommendations on how to apply the information that was gathered in the study. Therefore, if these basic requirements are met, then the thesis is complete. This thesis will be analyzed for these basic requirements, as well as being analyzed for how completely these requirements are met. The first part of the paper is the Introduction. The function of the Introduction is to introduce the problem, outline the promotional strategy, and give an outline of the research objectives, questions, structure, and theory behind the dissertation. Moreover, the introduction also provides a brief chapter overview, in which the introduction chapter is synthesized. The good was that the Introduction was well thought-out and well-organized. The introduction was superior in giving an overview and preview of what was ahead in the rest of the dissertation. What a good introduction does is whet the appetite – it is supposed to give brief synopses of all the different parts of the structure of the paper, and give a brief reason for the dissertation itself. This introduction did this very well, in that it was broken down into discrete parts that explained each of the sections of the thesis that was to come. Moreover, it outlined the research objectives very well – the objectiv es were concise and pinpointed, and gave a good framework for the rest of the dissertation. The reader knows what issues will be presented by looking at the objectives. There were also problems, in that the research questions were not as aligned with the research objectives as they could have been. The research objectives were very specific, and they encompassed much of what the research questions would not answer. Of course, it is possible that, through inquisition by the research questions, the dissertation could still answer and meet the objectives, but the questions should be more pinpointed to answer what the objectives of the research are. Therefore, the research questions probably should have been reworked so that they would more closely answer the issues which were presented in the objectives. Either that, or the objectives should be reworked to fit the research questions. Another section of the Introduction is the theoretical framework. This was a concise statement that gav e the overall dissertation some theoretical heft, but examining in brief the literature that is focused upon the dissertation’s subject. While much of this would also be in the literature review, it is still advisable to put this information also in the introduction so that the reader can have a brief explanation for what the literature is on the subject, and how this literature shows that the question that is presented is a pertinent one. It also gives a rationale for

Sexual Harassment - Term Paper Example Review of the Case After reviewing the case of sexual harassment, which went for trial and later on became the law in California, I believe that sexual harassment is a big problem for many of the working women these days. Many women face the problem of sexual harassment when they go to their offices for work. The dilemma is that most of those women do not report sexual advances of their colleagues and managers to anyone because they feel ashamed in front of others. In such cases, offenders get more courage and they continue doing sexual acts with their subordinates. In case of Zurian and Lawicki, Zurian also did not tell anyone about the sexual advances of Zurian, which encouraged Lawicki to continue harassing her sexually. Lawicki harassed Zurian physically and verbally for three years, which is a very awful example of the shameful act of sexual harassment. Lawicki used to grab Zurian’s breasts from behind, pinch her buttocks, touch her crotch, and make sexual inquiries. Zuri an was the subordinate of Lawicki because of which she was afraid that if she told anyone, it would not be good for her professional career. The fact is that there is a limit to everything. A person cannot continue to be victim of a crime for an endless period. That is the reason why Zurian finally decided to contact higher authorities for ending the sexual advances of Lawicki. ...

Morality has deeply influenced my professional practice, and decision making in the workplace context. Throughout my term as a summer trainee at Zain Telecom, I have demonstrated ethical decision making by doing what was right in each situation. Working in the Finance Department, which was one of the most critical functional units of the firm, I was responsible for sorting records and analyzing financial statements for the company. I had full accessibility to critical company information and financial records but I carried out my duties without tinkering at the information. I did what was ethically right and expected of me given my position and responsibilities for the role. I resorted to the company policy and acted in accordance with the code of conduct while handling the information. As such I displayed full integrity and responsibility with the critical financial information I was entrusted with. Because my career focuses on accounting and finance, auditing is a key component of my work. Auditing is a domain of accounting which demands ethical integrity and accountability in professional practice. During my term as a full-time Assistant Auditor at Delloite, I was exposed to financial information from a wide array of companies and organizations. Not only did I demonstrate integrity while handling information but I also did what was right by carrying out my duties of auditing the financials truly. My conduct was geared towards ensuring accurate and reliable financial information for the various clients. During my practice as an auditor, I ensured compliance with law and the ethical code of each firm. I responsibly explored the accounting system and reported only accurate information thereby reflecting aspects of Kantian ethics
