Question 1199925: An electric hoist consists of a drum 10 inches in diameter that lifts a load by winding a chain around the drum. Determine the number of degrees the drum must rotate to lift a piece of equipment 2 feet vertically.
Answer by htmentor(1343) (Show Source): You can put this solution on YOUR website!
The length of travel of the chain around the drum is given by L = A*R, where A
is the rotation angle in radians and R is the radius.
L = 2 ft = 24 inches
24 = A*10/2 -> A = 24/5 radians
Since pi rad = 180 deg, the angle in degrees is:
24/5*(180/pi) = 275.02 deg
