Wheel And Axle

A simple machine made of a wheel with a rod joined at its center, they rotate together

Real World Example

Imagine trying to open a tightly sealed jar lid with just your fingers. In this situation, you might wrap a towel around the lid for a better grip, which makes it easier to turn the lid. The towel acts like the wheel, giving you more leverage, while your hand is like the axle, applying force to twist the lid open. Just as the wheel and axle work together to magnify your effort, the towel and your hand work together to increase your grip and force, making it easier to overcome the resistance of the jar lid.
