Answer 2

Answer:

pitch

Explanation:

Pitch is the arrangement of turning the angle of the blade. Larger sized wind turbines have an active pitch control system. Each blade can rotate in its hub by means of a pitch motor. The pitch is controlled when very high speed winds blow on the tub or when there is a very slow wind. The generator of a wind turbine generates power only at winds of a prescribed speed. Power is not generated when there is a very slow or very high speed wind.
