Question

A total weight of 100 pounds is to be lifted using an inclined plane. Determine the

amount of force that would be required if the height is 2.0 ft and the length of the

inclined plane is 12.0 ft.

Answer 1

The force along the incline is

$$F_m=M\sin\theta=mH/L,\\ F_m=100·2/12=16.7\text{ lb}.$$
