Model the blades of a HAWT rotor as rods of equal length and mass, equally spaced around
Question:
Model the blades of a HAWT rotor as rods of equal length and mass, equally spaced around a circle, rotating with angular frequency Ω. Compute the moment of inertia of the rotor about the vertical axis. Show that the moment of inertia is independent of time as long as there are three or more blades.
