Balancing With This Simple Machine! | The Lever Song

The video tutorial introduces the concept of levers, a simple machine consisting of a fulcrum and a rigid beam, first described by Archimedes. It explains the components of a lever, including the fulcrum, effort, and load, and discusses the mechanical advantage that allows levers to multiply force. The tutorial also covers the three classes of levers, highlighting how the position of the fulcrum affects the effort needed to move a load.
