A 150 lb man stands on a 60 lb bar to which the cable is tied at B. The cable passes over two fixed pegs with coefficient of frictions as indicated. You may treat the cable the same as you would treat a flexible flat belt. assume the normal force exerted by the man in the bar acts downward through point A. Find the smallest force the man can exert on the cable if the bar is to remain horizontal.

Figure 2 В A Block A is hanging from a massless string which runs over a massless and frictionless pulley and connects to Block B. Block B slides over an inclined plane with ordinary kinetic friction. The plane under block B is inclined at an angle theta = 0 away from vertical. The other side of Block B is connected to another massless string which runs over another massless and frictionless pulley to connect to Cart C. Cart C rolls without friction over a plane which is inclined at an angle of phi = y away from vertical. C

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??
