Question: A wind turbine has 12,000 kg blades that are 37m long. The blades spin at 23rpm.
Part A: If we model a blade as a point mass at the midpoint of the blade, what is the inward force necessary to provide each blade's centripetal acceleration?
I need help to find the inward force necessary to provide each blade's centripetal acceleration.
