Use the following formula to calculate mechanical advantage. To lift a load, you apply 40.0 N of force to a lever. The lever applies 180 N of force to the load. What is the mechanical advantage of the lever?

The formula for mechanical advantage is MA = Load Force / Effort Force.
In this case, the Load Force is 180 N and the Effort Force is 40.0 N.
Therefore, MA = 180 N / 40.0 N = 4.5.
So, the mechanical advantage of the lever is 4.5.
