The principles of the lever are important in the field of mechanics. A lever is used to increase or decrease movement or force. The lever has three main components: the fulcrum, the effort force, and the load. Levers are usually divided into three types: 1st class (fulcrum in the middle), 2nd class (load in the middle), 3rd class (effort in the middle). These rules are used to simplify and optimize complex tasks
