Does the Direction Change of a Fixed Pulley Affect the Tension Force?

[Neil]

The direction change of a fixed pulley does not alter the tension force. When using a fixed pulley, the pulley with a stationary axis position is referred to as a fixed pulley: A fixed pulley does not save effort, for example, 2N=2N, but it can change the direction of the force. It is an application of the pulley principle and a discussion of mechanical work. Essentially, it is a lever with the effort arm equal to the resistance arm. If a fixed pulley is not used to change the direction of the force, what are its applicable scopes: Generally, when using a fixed pulley, it is mainly for situations where a group of people need to apply a force to an object. If the original direction is restricted by external conditions and normal force application is not possible, a fixed pulley can be utilized. By wrapping a rope around the fixed pulley and changing the angle, the process becomes convenient and labor-saving. For instance, when lifting a heavy object directly is not feasible, using a fixed pulley to pull downward allows the application of body weight, reducing reliance solely on arm strength.
