Though we can use either levers of class I or class II, for multiplying force, we should preferably use a lever of class II. This is because the mechanical advantage of levers of class II, is always greater than one.

Answer:
Lever of second type (or class II) is used as a force multiplier. In second class lever, the effort arm is always longer than the load arm and so its mechanical advantage is always greater than 1. So this lever acts as a force multiplier i.e., by applying a less effort, large load is lifted.
