One of the traditional types of simple machines is an inclined plane. Like the pulley and lever‚ the inclined plane provides a means of raising a heavy load easily. It is mainly useful for loading barrels since they can be rolled up the incline plane. The inclined plane was one of the machines available in ancient times. For example- the early Egyptians used inclined planes in the construction of the pyramids. Today many inclined planes are used in sports and recreation like water skiing and slides
