windmill speach 10lines
Answers
Answer:
A windmill is a machine that harnesses the power of the wind. Windmills may be used to grind grain into flour, to pump water, or to produce electricity.
A windmill has a number of blades that spin around when wind blows on them. The blades are mounted on a tall tower or building. They are connected to a vertical shaft, or rod. When the blades spin, they turn the shaft. The turning shaft powers a device that does work—for example, a water pump or millstones, which grind grain. The shaft also may provide power to a machine called a generator, which produces electricity.

Explanation:
A windmill is a structure used to harness the power of the wind for purposes like grinding grain, pumping water, and generating electricity.
The power of the wind was first harnessed by sailors, who were able to understand lift and harness the winds power through sails.It converts the wind's energy into rotational energy. ...
The energy made by windmills can be used in many ways. These include grinding grain or spices, pumping water and sawing wood. Modern wind power machines are used to create electricity. These are called wind turbines by engineers or wind mills by the average person.
