Levers, Wheels, Pulleys

The video explores the concept of simple machines, tracing their origins to the Renaissance and the works of Archimedes. It explains how simple machines like levers, wheels, and pulleys increase mechanical advantage by altering force direction and magnitude. Levers allow heavy objects to be lifted with minimal effort, while wheels and axles reduce friction and facilitate movement. Pulleys decrease the input force needed to lift objects. These principles are foundational to modern machinery, enabling the construction of complex structures.
