Question

If it takes 100 N to push a 300 n up an inclined plane, what was the mechanical advantage of the ramp

Answer 1

The mechanical advantage is defined as the ratio between the load (output force) and the effort (input force):

`MA = (L)/(E)`
for the ramp in our problem, the output force is 300 N, while the input force is 100 N, so the mechanical advantage of the ramp is:

`MA= (300 N)/(100 N)=3`
