class 1,2, and 3
first class lever second class lever third class lever
The three kinds of levers are classified based on the relative positions of the effort, the resistance, and the fulcrum. In a first-class lever, the fulcrum is between the effort and the resistance. In a second-class lever, the resistance is between the fulcrum and the effort. In a third-class lever, the effort is between the fulcrum and the resistance.

there are two kinds of pulleys. A movable pulley and a fixed pulley. But a wheel and axle have a lever and a inclined plane. [someone] :]

This device is called a joystick. It was a very common gaming device in the early days of video games and computers, but has largely been replaced by other kinds of controllers.
Levers can be found in various systems such as tools, machines, and human body. There are three types of levers based on the relative positions of the fulcrum, resistance, and effort: first-class lever, second-class lever, and third-class lever. Examples include seesaws (first-class), wheelbarrows (second-class), and shovels (third-class).
A fulcrum in a lever is very important because without a fulcrum a lever isn't a lever , and the fulcrum is the main part of a lever.
