'Calculate the mechanical advantage of a crowbar that need an effort of only 20N to move a load of 400N ?'

Given: Load force = 400N, Effort force = 20N

To find: Mechanical advantage of a crowbar

Solution:

We know that Mechanical advantage=$\frac{ Load \ force}{effort \ force}$

=>

Mechanical advantage= $\frac{ 400}{20}$

= 20.
