pulley Wheel teaching component

Pulley is a simple mechanical device in mechanical engineering, mainly used to change the direction and magnitude of applied force. Pulleys can be divided into fixed pulleys and movable pulleys. Below, I will analyze the working principles and characteristics of these two types of pulleys separately. ###Fixed Pulley**Working principle:**A fixed pulley is a wheel that is typically installed in a stationary position. The rope or chain wraps around this wheel, with one end connected to the load and
