Question

The mechanical advantage of a broom stick is always greater than 1

• A. True
• B. False

Answer 1

The correct option is B False

$\text{Solution}:$

1. In a broom stick, the handle of the broom at the top is the fulcrum, we push the handle from somewhere in the middle, that is the input effort and the bristles at the end of the broomstick sweep dust from the floor, that is the output load.

2. Therefore, a broomstick is a lever of class 3. Hence, its mechanical load is always less than 1.

$\text{Hence B is the correct option}$
