Question

In a 3rd class lever what is the mechanical advantage when force arm = 10m and resistance arm = 18m. *

Answer 1

The mechanical advantage of the lever is 0.56.

Explanation:

The ratio of effort arm to the resistance arm is called mechanical advantage of  a lever. For a 3rd class lever, we need to find the mechanical advantage when force arm is 10 m and resistance arm 18 m. So, it can be given by :

$m=\dfrac{10}{18}\\\\m=0.56$

So, the mechanical advantage of the lever is 0.56.
