Question:
Which class lever is called force multiplier and why?
Answer:
Lever of second type (or class II)
Step-by-step explanation:
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.
