Output force divided by input force is the mechanical advantage.
A tool, mechanical device, or machine system's ability to amplify force is known as its mechanical advantage. The system simply balances forces against movement in order to achieve the desired output force amplification while maintaining the input power. The law of the lever can be used as an example for this.
Levers and pulleys are examples of simple machines that use mechanical advantage, a measurement of the ratio of output force to input force in a system.
A calculation known as a mechanical advantage quantifies the amplified force that a mechanical system absorbs. It provides the ratio of force applied to the load to force required to overcome that force. Since the two ratio quantities are the force, the expression has no units.
