The most basic machines are levers, which are used to do tasks with little effort. The term "leverage" refers to how a lever amplifies an input force to produce a larger output force. We know that several sorts of levers exist based on the fulcrum location, force, and weight. This category encompasses any tool that is used to complete a task.
There are three sorts or classes of levers, depending on where the weight and effort are positioned in relation to the fulcrum:
- Lever of the First Class
- Lever of 2nd Class
- Lever of the Third Class
