Question

A simple pulley reduces the effort required to lift a heavy load.

• A. True
• B. False

Answer 1

The correct option is A True

$\text{Solution}$:

1. A pulley with one wheel allows you to reverse the direction of your lifting force by pulling down on a rope (that’s looped over the wheel), lifting your weight.

2. With a two-wheel pulley, you reduce the effort you exert to lift the same amount of weight. You lift the weight with half the force.

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