Pulleys: Fixed, Movable and Systems
Pulleys: Fixed, Movable and Systems

Students construct a complex system of six pulleys and determine its ideal mechanical advantage. They then use the system to lift a weight and measure the work input and energy output of the system. They calculate the actual mechanical advantage...
