What does the provided illustration show an example of?

A lever
An inclined plane
A pulley system
Wheel and axle

The correct answer is: A lever

The illustration represents a lever, which is a simple machine that facilitates the lifting or moving of heavy objects with less effort. A lever consists of a rigid bar that pivots around a central point known as the fulcrum. When force is applied to one end of the lever, it helps to amplify that force at the other end, allowing for the lifting of a load with greater efficiency. In the case of a lever, the position of the fulcrum, the amount of load on one side, and the force applied on the other side play crucial roles in how effectively the lever operates. By using a lever, one can perform tasks, such as lifting heavy objects or even applying significant force with minimal effort, which is fundamentally how levers work in mechanics. This principle helps increase mechanical advantage, making work easier and more efficient.
