Asked by ashlee

a man has only 4 simple pulleys to lift a heavy load of 6000N. in roder to lift the load easily, he combines the pulleys (3 moveable, 1 fixed). given that the frictional forces are 300N, what force must he apply in order to lift the load?
Answered by drwls
The ideal mechanical advantage is 4, the number of pulleys. The ideal force required to lift 6000N would be 6000/4 = 1500 N.

Add 300 N to that for frictional resistance.
