Brief description from Boy Scout Rope Making Machine above :
Heron of Alexandria in his study listed the five mechanisms as the lever, windlass, pulley, wedge, and screw, which were known to set a load in a motion. Flemish engineer Simon Stevin derived the mechanical advantages of the inclined plane that was merged with the simple machines. Leonardo da Vinci also contributed to the study of machines by discovering the classic rules of sliding friction.
