A hoist with 1.2 m diameter drum lifts a cage by means of a wire rope that winds on the drum. The drum is driven by an electric motor through a double reduction gear. Determine the motor torque to give the cage acceleration upwards of 0.9 m/s^2, given the following data: Speed (rev/min) 1440 340 75 75 Mass (kg) 230 360 900 1100 1800 450 k (mm) 115 240 650 550 - Rotor of motor Intermediate gear Low speed gear Drum and shaft Cage Rope

A hoist has a winding drum 0.9 m effective diameter and a radius of gyration of 0.35 m, the mass of the drum being 100 kg. A load of 320 kg is to be raised 36 m, the mass of the lifting rope being 1 kg/m. If the acceleration is 1.8 m/s2 until a constant velocity of 6 m/s is reached, find the power necessary just at the end of the acceleration.

A motor supplies a constant torque $M=6 \mathrm{kN} \cdot \mathrm{m}$ to the winding drum that operates the clevator. If the elevator has a mass of $900 \mathrm{kg}$, the counterweight $C$ has a mass of $200 \mathrm{kg}$, and the winding drum has a mass of $600 \mathrm{kg}$ and radius of gyration about its axis of $k=0.6 \mathrm{m},$ determine the speed of the elevator after it rises $5 \mathrm{m}$ starting from rest. Neglect the mass of the pulleys.
