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 beraised 36 m, the mass of the lifting rope being 1 kgim. If the acceleration is1.8 mis2 until a constant velocity of 6 mis is reached, find the power necessary just at the end of the acceleration.
