Question

A nut cracker takes an effort of $4\text{kgf}$ for a load of $6\text{kgf}$. What is its mechanical advantage?

• A. 1.5

Answer 1

The correct option is A 1.5
Given:
The load, $\text{L}=6\text{kgf}$
The effort, $\text{E}=4\text{kgf}$
Mechanical advantage, $\text{M.A.}=\frac{\text{L}}{\text{E}}=\frac{6}{4}$
$=\frac{3}{2}=1.5$
