Bales of hay of 40 lbf move up a conveyor set at 30° angle to the ground. if the hay bales are moving at 1.5 ft/sec, determine the power required to move each bale, neglecting any wind or air resistance.

The power required to move each bale is 30 lbf.ft/sec.

Explanation:

F= 40lbf * sin (30º)

F=20lbf

P= F*v

P=20 lbf * 1.5 ft/sec

P= 30 lbf.ft/sec
