Mechanical advantage

Mechanical advantage refers to the benefit gained from using a tool or machine to lift or move objects. It allows a person to exert less effort to achieve the same outcome, making tasks easier. For example, when using a lever, a small force applied to one end can lift a heavier object on the other end. Mechanical advantage is calculated as the ratio of the output force to the input force. Essentially, it measures how much a machine amplifies your effort, enabling you to do more with less energy.
