Question

A load is to be pulled up an inclined plane using a pulley system. The inclined plane is 25.0 ft long and 5.00 ft high. The pulley system has 2 fixed pulleys and 1 movable pulley. Find the mechanical advantage of this compound machine.

Answer 1

Advantage equals 0.1, mate
1) advantage of plane: 5 divided by 25 = 0.2
2) advantage of fixed pulleys = 0
3) advantage of movable pulley = 0.5
4) and you multiply 0.2 and 0.5 = 0.1
