The 20-lb disk rests on the 5-lb plate. A cord is wrapped around the periphery of the disk and attached to the wall at B. Determine the needed torque M pplied to the disk so that the end C of the plate to travel 16 ft and strike the vall for Is. Assume the disk does not slip on the plate and the plate rests on he surface at D having a coefficient of kinetic friction of a = 0.1. Neglect he mass of the cord. %3!
