Question
A motorised gearbox has a reduction ratio of 50:1. The power input to the gearbox is 5 kW at 1440 RPM. The gearbox efficiency is 85% under maximum load conditions. The output shaft of the gearbox is attached to a winch drum of pitch diameter 220 mm and is used to hoist a load.
Determine the maximum speed at which a load may be lifted and the maximum load capacity (in tonnes) of the winch. Frictional losses in the winch drum itself may be neglected.
PLEASE FULL WORKING! THANK YOU!
