Simple Machines: Levers (2nd Ed, 1984)

Discusses the principles of levers, a type of simple machine that helps lift heavy loads by changing the direction or magnitude of force applied. It explains how the position of the fulcrum affects the amount of force needed to lift a load and demonstrates various applications of levers in tools such as shovels, hammers, scissors, and wheelbarrows. The film emphasizes the trade-off between force and distance based on the fulcrum's location, illustrating how levers can be used to amplify force or increase speed in different scenarios.
