Simple Machines

Simple Machines. Ancient people invented simple machines that would help them overcome resistive forces and allow them to do the desired work against those forces. Simple Machines. The Lever. A lever is a rigid bar or board that rotates around a fixed point called the fulcrum .

Lever Systems

Lever Systems. Classified systems of torque Relative positions of force, resistance, and axis of rotation vary in the different types or classes of levers As with any torque calculations, operations on levers determine the tendency for some force to produce rotation around a fixed point.
