The classification of levers is based on the relative positions of the effort, load, and fulcrum. There are three types of levers: first-class levers have the fulcrum placed between the effort and load, second-class levers have the load between the fulcrum and effort, and third-class levers have the effort between the fulcrum and load.
People use levers in a variety of situations, such as on seesaws at playgrounds, in construction to lift heavy objects, and in tools like crowbars to pry things apart. Levers are also used in machinery and equipment to make tasks easier by providing mechanical advantage.
There are three classes of levers: first-class lever, second-class lever, and third-class lever. Each class is categorized based on the relative positions of the input force, the fulcrum, and the output force.
