Archimedes (theory of levers)

Archimedes' theory of levers states that a lever amplifies input force by using a fulcrum (pivot point), allowing a small effort to move a larger load. It operates based on the principle of moments: the product of the force and its distance from the fulcrum is the same on both sides. Essentially, if you increase the distance from the fulcrum, you can exert less force to achieve the same effect. This insight explains how ancient humans could lift heavy objects with simple tools, emphasizing the importance of leverage and balance in mechanics.
