Question

When does a machine act as (a) a force multiplier (b) a speed multiplier? Can a machine act as a force multiplier and speed multiplier simultaneously?

Answer

A machine acts as a force multiplier when the effort arm is longer than the load arm. The mechanical advantage in such cases is greater than 1.
A machine acts as a speed multiplier when the effort arm is shorter than the load arm. The mechanical advantage in such cases is less than 1.

No, it is not possible for a machine to act as a force multiplier and speed multiplier simultaneously.
