Pulleys are one of the six simple machines. The other simple machines are the wheel and axle, the inclined plane, the wedge, the screw, and the lever. A machine is a tool used to make work easier, and the six simple machines were some of mankind’s earliest discoveries.

Students learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys.

History. Pully is first mentioned in 994 as Pulliacum.. Prehistory. In 1826 a neolithic cemetery with about 30 graves was uncovered at Pierra-Portray. However, the artifacts were not fully preserved and only one flint blade and a soapstone fragment still exist. Near Pierra-Portray, along the Chemin de Chamblandes, Albert Naef examined 23 tombs in 1901-10.

Pulley definition is - a sheave or small wheel with a grooved rim and with or without the block in which it runs used singly with a rope or chain to change the direction and point of application of a pulling force and in various combinations to increase the applied force especially for lifting weights.
