A 10 HP Motor turning 1800 rpm is attached to a 60:1 speed reducing gearbox. The motor has an efficiency of 80%. It operates at 240V AC. A 12" diameter drum is attached to the gearbox output shaft, and a wire rope is wrapped around the drum to act as a winch. The winch is used to raise bucket of raw material in a factory.

A). What is the rotational speed of the drum in rpm?

B). What is the linear speed of the wire/bucket in fps?

C). What is the maximum weight that the winch can lift in lbs?

D). What is the work done in lifting the maximum weight to a height of 50 feet?

E). What is the current draw of the motor during this operation?
