Question

Consider a lever which is always used as a force multiplier. How is the effort arm related to the load arm in such a lever ?

• A. Effort arm = load arm
• B. In this type of lever the effort arm is made shorter than the load arm.
• C. both (A) and (B)
• D. In this type of lever the effort arm is made longer than the load arm.

Answer 1

The correct option is D

In this type of lever the effort arm is made longer than the load arm.

The lever of class 2 is always used as a force multiplier. In this type of lever the effort arm is made longer than the load arm so that its mechanical advantage is always greater than 1. That is, by applying a small force a large load can be lifted
