Electro-Mechanical Control Systems - Assignment Example

Top-down approach in problem solving is used to solve the problems in different stages and sections. Thus, it is rather easier to solve the smaller problems rather than solving a big problem. It is rapid process of solving the problems. Rather than decreasing the viability of the solution, it enhances the reusability of the solutions and provides solution for various other problems regarding the problems or encircling the major given or discussed problem. Makes larger problems into smaller parts that can easily be solved and remain more manageable.

Makes it easier to evaluate the sources of problem and correct the problem from source. In general, top-down approach splits the problems in smaller sections and parts that make the problems easier to solve and more manageable in every manner. The quality of the results remains much better as compared to that presented by other problem solving approaches. At the end, the individual results are combined to solve the problem on a scale (Mathieu, 2002). Ball Screw is a liner actuator that converts rotational motion of a moor or a rotating shaft into linear displacement.

It presents very little resistance due to the ball bearing mechanism for the linear displacement of the screw. The assemble with the ball bearings act as the nut of the device while the rotating shaft or the threaded shaft acts as the screw of the device. When the nut assembly moves with respect to the rotating shaft, the balls move inside the nut assembly. There is no direct physical contact between the nut and screw. Ball bearings support and hold both the nut and screw assembled together. The whole mechanism makes the Ball screw to present lowest tolerance and highly precision at every stage.

The shaft of the ball screw or the rotating shaft holds the ball bearings and presents helical raceway for the ball bearings. In this manner, the ball screws are able to with stand heavy loads
