Question

You apply an input force of 12.5 N to the nutcracker while the output force is 50.0 N. What is the actual mechanical advantage of the nutcracker?

Answer 1

The mechanical advantage (MA) of a machine is the ratio of the output force to the input force. In this case, the output force is 50.0 N and the input force is 12.5 N, so we can use the formula:

MA = output force / input force

MA = 50.0 N / 12.5 N

MA = 4

Therefore, the actual mechanical advantage of the nutcracker is 4
