A pulley is a shaft or a wheel on a shaft designed to support the movement and change of direction of a taut cable or belt, or to transfer power between the shaft and the cable or belt. In the case of a pulley supported by a frame or housing that does not transmit power to an axis but is used to guide the cable or apply force, the supporting housing is called a pulley and the pulley may be called a pulley.
Pulleys may have one or more grooves between flanges around their circumference to position cables or belts. The pulley system may be driven by a rope, cable, belt, or chain.
The simplest operating theory of a pulley system assumes that the pulley and wire are weightless and that there is no loss of energy due to friction. And let's say the line doesn't stretch.
In equilibrium, the sum of the forces on the moving block must be zero. In addition, the tension in each part of the rope must be the same. This means that the two parts of the rope supporting the moving block must each support half of the load.
