The wind turbine in the figure consists of three equally spaced blades that are rotating as shown about the fixed point O with an angular velocity wo = 26 rpm. Suppose that each 38000 lb blade can be modeled as a narrow uniform rectangle of length b = 182 ft, width a = 12 ft, and negligible thickness, with one of its corners coinciding with the center of rotation O. The orientation of each blade can be controlled by rotating the blade about an axis going through the center O that coincides with the blade's leading edge.
