– Simple machines are made up of one part of just a few parts. The pulley, the inclined plane and the lever are the most common simple machines.
– Complex machines are made up of many parts. These parts usually include the motor, the operating parts, the cover, the screens and indictors, the structure and the control components.
– Operating parts transmit movements. Two or more operating parts working together are a mechanism. Gears are examples of mechanisms.
