A wedge assembly, composed of wedges X and Y, is designed to lift crate W whose weight is 1936 N, as shown in the figure below. What will be the maximum force P that can be applied before movement begins if the coefficient of friction for all surfaces of contact is 0.0875? Draw all necessary free-body diagrams and indicate the direction of impending motion.

O d. 90 [kN] Clear my choice The crate has a weight of 490 lb and a center of gravity at G rests on the floor for which the coefficient of static friction is equal to 0.3. If the force P = 200 lb is applied as shown in the figure below.

A flat belt passes over two idler pulleys and under a rotating drumof diameter 8 in. The axle of the drum is free to move vertically ina slot, and a spring keeps the drum in contact with the belt. Whatis the minimum force which should be exerted by the spring if slippageis not to occur when a 30-lb · ft torque is applied to the drum? Thecoefficient of static friction between belt and drum is 0.30 and theangle of contact is 180 degrees.
