The 750 kg elevator is operated as the cable winds around the rotating drum (r=0.2 m) A which is driven by a motor. Determine the constant torque M which must be supplied to the shaft of the drum by the motor in order to give the elevator an upward velocity of 3 m/s in a vertical rise of 4 m starting from rest. Neglect the mass of the drum and assume it is in rotational equilibrium (constant rotational speed). Neglect friction.

A skyscraper in Manhattan has an elevator that weighs 1000 kg when loaded. The elevator is lifted at a constant rate to 480m above the ground by an electric winch motor. The drum of the winch motor is a solid uniform cylindrical drum in which a steel cable can wrap around it. The mass of the drum is 500 kg and has a diameter of 1 m. It takes the elevator a total of 120 s to get to the...
