Discussion Worm and Wormwheel Essay Example

Discussion Worm and Wormwheel Paper The worm and worm wheel is a very important mechanism in the field of Mechanical engineering. It has the ability to lift heavy loads with very little effort and keep the load raised and locked in a desired vertical position without any effort. The main objective of this experiment was to investigate the behavior of the worm and worm wheel gear set. Unfortunately, all the objectives of this experiment werent fulfilled in this session due to the following factors: The experiment was done only using a single starter worm The experiment was done by using only one gear which had 40 teeth. The apparatus was recently repaired and consequently, it affected the experiment results to a certain extent. However, the experiment was fully conducted for a single started worm in mesh with a 40 teeth gear set. To start the experiment, the effort pulley and the load drum were loaded with appropriate weights and wound. After the weights were loaded, a small downward pull was given to the effort hanger in order to overcome the static friction. It was advised that this manual downward pull should be given by the same person and the Orca should be the same throughout the whole experiment since it could affect the experiment results adversely if done otherwise. And it was also advised that when releasing the effort, the effort hanger should be released from the same vertical height. Although the reason for this is not fully explainable, it can be assumed that this was either because the surface nature of the effort cord was not uniform or due to the number of rotations of the effort cord on the effort pulley that caused a slight difference in the friction between the cord segments.

The tabulated data was then plotted to obtain a graph after further calculations. The graph was drawn for Actual effort (EAI) vs.. Applied load (F) to find the Law of the machine. During the experiment, there were few conflicts in opinions. Instances for such discrepancies were when at some attempts, the effort was able to lift the load with a mass very low than expected. The reason for this phenomenon is also not completely explainable since physical concepts such s static and dynamic friction are still not quite clearly understood. But it could be assumed that this was due to human error because the initial downward pull was applied manually and there was a chance that the pull was not uniform in all instances of the experiment. In this worm and worm wheel gear set, the machine may not provide a continuous efficiency for all loads since there is a limit to its efficiency. The limiting efficiency for this apparatus can be termed as the reciprocal of the product of the velocity ratio and the slope of the graph drawn for the Law of the machine.

The Legal Issues Scenarios - Case Study Example â€Å"Top off† social security and unemployment benefits arise in the case of Heinrich while in the case of Christine, discrimination in the selection, mandatory language tests and pension requirements are at issue. In the case of Max, the legal issue that arises is the right to equal access to loans for education, while in Klara’s case there may be the problem of sex discrimination. Additionally, legal issues connected to reasons for the proposed deportation of the family must also be taken into account. Article 18 of the EC Treaty allows the right to free movement of persons within the European Union, while Article 12 lays out a general principle of non-discriminatory conduct to be applied to all EU citizens. Directive 2004/38 has in fact expanded the scope of Article 12 and has put in place new provisions for the free movement of persons within the EU. Close has argued for supranational democratic citizenship for the European Union, on the basis that citizenship regulated by national considerations is undemocratic in its origin.1 The major issue that arises in the case of both Christine and Heinrich is the question of equal pay for equal work, which is mandated by Article 141 of the EC Treaty. However, before this aspect can be assessed, it must be determined whether they first qualify as â€Å"workers†. A general definition of worker has been set out in Lowrie Blum2 stating the essential feature that characterizes a worker is that â€Å"for a certain period of time a person performs services for and under the direction of another person for which he receives remuneration.† This will be applicable to Heinrich, Christine, and Klara who will all qualify as workers and will be entitled to a range of community rights applicable in all Member States3.
