If wind turbine blades are so long and heavy, how is the wind able to rotate them?
In: 5
That’s the thing, they’re *not* very heavy compared to how big they are and how much surface they have for the wind to push on. Also they’re balanced around the center hub so it takes less force to rotate the wheel of them. It’s not like the wind has to actually lift the weight of a whole blade, the weight of the opposing blade does that!
