and carry a great amount of angular momentum when rotating. A wind turbine has a total of 3 blades. Each blade has a mass of m =
5500 kg distributed uniformly along its length and extends a distance r = 44 m from the center of rotation. The turbine rotates with
a frequency off= 13 rpm.
Part (a) Enter an expression for the total moment of inertia of the wind turbine about its axis of rotation, in terms of the defined quantities.
