Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

The figure shows a system with a block m1 attached to a simple square thread screw with a mean diameter of 10 mm, a pitch of 3 mm and whose coefficient of static friction on the thread is 0.35. Block m1 is attached to block m2 by a rope, each of blocks m1 and m2 have a mass of 4 kg.Block m2 is in turn attached to a 15-kg block W by another rope, which passes over a static drum where the coefficient of static friction is 0.20. Determine the required Moment M that must be applied to the screw to start lifting block W. The coefficient of static friction between the surface and blocks m1 and m2 is 0.25.

A simplified disk brake assembly is shown. A force F = 30 lb is applied to the lower end of the massless brake lever at a distance d from the lever’s pivot O. The brake is located L = 0.2 ft from O at the upper end of the lever, and the coefficient of friction between the brake and the disk is ? = 0.7. The disk has a weight and radius of W = 120 lb and R = 0.25 ft, respectively, and it is initially spinning at a constant ?o = 1000 rpm. What should d be if the disk is to come to a stop in Δ? = 1??
