A wind turbine has 12,000 kg blades that are 37m long. The

blades spin at 23rpm .

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?

1rpm = 2pi/60 rad/sec

centripetal force F = mv^2/r or mr

w^2

F = 12000 * ((37/2) * (23*2*3.14/60)2

F = 1.286 *10^6
