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

Answer:

m = 2.4

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,

$m=\dfrac{12}{5}\\\\m=2.4$

So, the mechanical advantage of his ramp is 2.4.
