Physics Diagram of Pulley Mechanism

This diagram provides a clear visual comparison of four different pulley setups, demonstrating how adding more movable pulleys changes the mechanical advantage. From a single fixed pulley (1:1 ratio) to a more complex system with multiple movable pulleys (up to 1:4 ratio), the image illustrates how the effort required to lift a load decreases as the number of supporting rope segments increases. It's a great reference for understanding the principles of simple machines and force distribution in pulley systems.
