Each of three helicopter rotor blades is 5.20 m long and has a mass of 221 kg. The rotor is rotating at 211 rev/min. (a) What is the rotational inertia of the rotor assembly about the axis of rotation? (Each blade can be considered to be a thin rod rotated about one end.) (b) What is the total kinetic energy of rotation?
