What are the three types of levers give examples of each?

The three types of levers are first-class, second-class, and third-class levers. In a first-class lever, the fulcrum is positioned between the effort and the load, such as in a seesaw. A second-class lever has the load between the fulcrum and the effort, exemplified by a wheelbarrow. In a third-class lever, the effort is applied between the fulcrum and the load, like in a pair of tweezers.
