A fixed pulley is a simple machine that consists of a wheel and a rope. It is used to change the direction of a force. A fixed pulley is attached to a fixed point, and the rope is wrapped around the wheel. When a force is applied to the rope, the wheel turns and the force is changed in direction.

Fixed pulleys are used in a variety of applications, such as lifting heavy objects, changing the direction of a rope, and creating a mechanical advantage.
