Question

A child makes a ramp to push his toy dump truck up to his sandbox. If he uses 5 newtons of force to push the 12-newton truck up the ramp, what is the mechanical advantage of his ramp?

Answer 1

m = 2.4

Step-by-step explanation:

Given that,

Input force,
`F_i=5\ N`

Output force,
`F_o=12\ N`

We need to find the mechanical advantage of the ramp. The ratio of output force to the input force is equal to mechanical advantage. So,

`m=(12)/(5)\\\\m=2.4`

So, the mechanical advantage of his ramp is 2.4.
