Question

Calculate the mechanical advantage of a lever whose effort arm is $50cm$ and the load arm is $2cm$.

• A. $25$
• B. $5$
• C. $35$
• D. $2$

Answer 1

The correct option is A

$25$

Given,

Effort arm = $50cm$,

Load arm = $2cm$

Mechanical advantage = $\frac{\text{effort arm}}{\text{load arm}}=\frac{50}{2}=25$
