hey!
Wind turbines have got certain threshold speed of wind (of about 6-7 m/s) which acts as a mechanical resistance to its rotation.
Is this mechanical resistance a result of frictional resistance in bearings alone, or it is also a result of its own weight?
If yes, approximately how much of it is contributed by both of them??
