Carly Roberson · Answer 1

The formula of mechanical advantage in this situation is:

MA = Input Force : Output Force

The input force is the 30N applied to a screwdriver while the output force is the 75N force to the lid.

So,

MA = 30N/75N

MA = 0.40

Hence the mechanical advantage of the screwdriver is 0.40.
