Answer:

<h2>The input force is 87.27N</h2>

Explanation:

Mechanical advantage (M.A)of a machine is the ratio of load to effort

<h2>Given</h2>

M.A= 5.5

load= 480N

effort= ?

Applying the formula and substituting to find the effort we have

$M.A= \frac{load}{effort}$

$5.5= \frac{480}{effort}\\\effort= \frac{480}{5.5} \\\effort= 87.27N$
