mechanical energy. A windmill is used for grinding grain, pumping water for
irrigation and in the past few years for generating electricity.
IDENTIFICATION :
A common windmill consists of a high steel tower on top of which revolves an
air motor. The parts of the air motor are fixed onto the wind shaft and are
automatically held into the wind or
furled according to whether water should be pumped or if the mill needs to be
protected from the severity of the wind.
