what is pulley? How does it help in lifting weight?

Answers

Hey there!

A pulley is a "system" that has a rope attached to carry heavy materials off the ground. Once you pull the rope, the heavy item will be carried.

Hope this helps!

Have a great day!

Using a pulley greatly multiplies the force of your physical efforts. 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. ... The more wheels your rope can loop around, the more weight you will be able to lift.
