6.2
To calculate mechanical advantage, you use the formula:
Mechanical Advantage = Load Force (output force) / Effort Force (input force)
In this case:
Load Force = 180 N
Effort Force = 40.0 N
Mechanical Advantage = 180 N / 40.0 N
Mechanical Advantage = 4.5
Therefore, the mechanical advantage of the lever is 4.5.
A machine will always have less output work than the work put into it.
