Question

state the usefulness of such a machine which has MA less than one​

Answer 1

Sometimes the mechanical advantage of a machine is less than one. That is, a person has to put in more force than the machine can move. ... The purpose of a class three lever, therefore, is not to magnify the amount of force that can be moved, but to magnify the distance the force is being moved.
