What is a machine?

Answer

A machine is a simple, compound or complex mechanism that does work or assists in the completion of work. For thousands of years, mankind has used six simple machines that harness the laws of physics to simplify the work of difficult tasks.

Simple machines are the lever, wedge, inclined plane, pulley, screw and wheel and axle. An example of a compound machine is a pair of scissors; the blades of the scissors move on a fulcrum and act as a lever, and the edges of the blades are sharpened to form wedges for cutting. Complex machines combine several simple machines working together to accomplish one work goal.
