Illustrated in the figure is a 1 ½ -in-diameter steel countershaft that supports two pulleys. Pulley A delivers power to a machine causing a tension of 600 lbf in the tight side of the belt and 80 lbf in the loose side, as indicated. Pulley B receives power from a motor. The belt tensions on pulley B have the relation T1 = 0.125T2. Find the deflection of the shaft in the z direction at pulleys A and B. Assume that the bearings constitute simple supports.
