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.

What are the two main components of a lever?

Who introduced the concept of the lever and in what year?

What is the mechanical advantage of a lever and how is it calculated?

Explain how the position of the fulcrum affects the effort needed to move a load.

Describe the difference between first class, second class, and third class levers.
