Compute the torque developed by an industrial motor whoseoutput is 175 {\rm kW} at an angular speed of 4000 {\rm rev}/{\rm min}.
A drum with negligible mass and 0.600 {\rm m} in diameter is attached to the motor shaft, and thepower output of the motor is used to raise a weight hanging from arope wrapped around the drum. How heavy a weight can the motor liftat constant speed?
At what constant speed will the weight rise?
