How many ways can a simple pulley be set up?

A simple pulley system can be set up in a variety of ways depending on the number of pulleys and the arrangement. Typically, a single fixed pulley can be used to change the direction of force, while a movable pulley can reduce the effort needed to lift a load. If multiple pulleys are combined, they can create compound systems that further reduce effort. Overall, the configurations can vary widely, but the basic setups primarily involve fixed and movable pulleys.
