6/160 The motor at B supplies a constant torque M which is applied to a 375-mm-diameter internal drum around which is wound the cable shown. This cable then wraps around an 80-kg pulley attached to a 125-kg cart carrying 600 kg of rock. Beginning from rest, the motor is able to bring the loaded cart to a cruising speed of 1.5 m/s in 3 seconds. What torque M is the motor able to supply, and what is the average value of the tension in each side of the cable which is wrapped around the pulley at O during the speed-up period? The cable does not slip on the pulley and the centroidal radius of gyration of the pulley is 280 mm. What is the power output of the motor when the cart reaches its cruising speed?
