Question

In which case it will be easiest to lift an object using a lever?

• A. Effort arm = Load arm
• B. Effort arm < Load arm
• C. Effort arm > Load arm
• D. All of the above.

Answer 1

The correct option is C

Effort arm > Load arm

The lever acts as a force multiplier if the effort arm is bigger than the load arm. Hence, the small force as an input will give a large amount of force as an output. Thus, it will be easy to lift an object with the help of a force multiplier.
