A lever is an adaptation of a stick or tree branch. A pulley is an adaptation of a wheel.

A lever and a pulley are different. They are both simple machines that have been around for over two thousand years and described in detail by a Greek named Archimedes.

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] :]

maybe the pulley but not the lever he invented the pulley but not the lever
A lever is a simple machine consisting of a rigid rod or beam that pivots around a fixed point called a fulcrum to multiply force. A pulley is a simple machine that consists of a wheel with a groove around its circumference and a rope or belt that runs along the groove to lift or move objects. Essentially, levers are used to amplify force, while pulleys are used to change the direction of a force.
what is
A pulley is a class 1 lever because the fulcrum (pivot point) is between the load (object being lifted) and the effort (force applied to lift the load).
No, The Greek Scientist who founded the Lever and Pulley is Archimedes.
Pliers are a lever

No, a pulley is not a third class lever. A pulley is a simple machine that consists of a wheel with a groove around its circumference, used for lifting or moving objects. Third class levers have the input force between the fulcrum and the output force.
A pulley has an axle or pivot just like a lever has a fulcrum. Just as a lever tilts across a fulcrum and the fulcrum bears all the weight, a pulley rotates around its pivot/axle the same way. So in essence, a pulley is a lever wrapped into a wheel, with its fulcrum in the center.
