About This Product
Teachers use the model to show that a fixed pulley changes the direction of a force while a movable pulley reduces its size. Students lift a load with different pulley combinations, measure the effort and work out mechanical advantage as the ratio of load to effort, then discuss tension, equilibrium and the efficiency of the system. Laboratories and colleges in Mauritius, Estonia, Armenia, Lithuania and Namibia can buy the Pulley Demonstration Model through an export order.
