A 16-kW, 1500-rpm electric motor drives a machine through multiple V-belts. The V-belts used have a unit weight of 0.214 kg/m. The sheave on the motor shaft has a 94 mm pitch diameter and the angle of wrap is 165. It is conservatively assumed that the maximum belt tension should be limited to 650 N and that the coefficient of friction is 0.3. How many belts are required?
