Question

4. A man applied a force of 50N to the nutcracker. The nutcracker applies a force of 750N to the pecan. What is the mechanical advantage?

Answer 1

Mechanical advantage show how much the applied force is amplifyed. If $F_N$ is a force, applied by the nutcracker and $F_M$ is a force, applied by the man to the nutcracker, the mechanical advantage $MA=F_N/F_M=750/50=15.$
