Answer:

It is not possible for a machine to act as a force multiplier and speed multiplier simultaneously. ... For a machine of a given design, the velocity ratio does not change. (9)This is because the output work is always less than the input work, so the efficiency is always less than 1 because of energy loss due to friction.
