Question

Yosef applies an input force of 50 N to a crowbar. The crowbar applies a force of 750 N to the lid of a crate. What is the mechanical advantage of the crowbar?
The mechanical advantage of the crowbar is
.

Answer 1

The mechanical advantage would be 15.

Answer 2

Explanation:

Given that,

Input force applied by the Yosef to a crowbar, $F_1=50\ N$

Output force applied by the crowbar, $F_2=750\ N$      

We need to find the mechanical advantage of the crowbar. The mathematical formula of the mechanical advantage is given by :

MA = output force/input force

$MA=\dfrac{F_2}{F_1}$    

$MA=\dfrac{750}{50}$            

MA = 15

So, the mechanical advantage of the crowbar is 15. Hence, this is the required solution.
