The Lever and Fulcrum is a simple machine essential in physics experiments and laboratory settings. A lever, which is a rigid bar pivoted on a fixed point called the fulcrum, is a fundamental part of this elegant mechanical setup, utilized in a variety of scientific applications to efficiently increase force and manipulate direction.

Experts use these components to demonstrate the lever arm concept, where the fulcrum distance affects force. This setup is usedl in experiments on rotational motion, equilibrium conditions, and force transfer.
