Simple Machines: Working Together (1984)
Explains how simple machines, such as levers, pulleys, wheels and axles, and inclined planes, work together to make tasks easier by trading force for distance or vice versa. It illustrates the concept of work, defined as the product of force and distance, and how mechanical advantage is achieved by combining these machines. By manipulating the lengths of levers and the configurations of compound machines, one can significantly increase the output force, demonstrating the effectiveness of simple machines in everyday applications.
