Let us treat a helicopter rotor blade as a long thin rod, as shown in Fig. 8-49.

Question:

(a) If each of the three rotor helicopter blades is 3.75 m long and has a mass of 135 kg, calculate the moment of inertia of the three rotor blades about the axis of rotation.

(b) How much torque must the motor apply to bring the blades from rest up to a speed of 6.0 rev/s in 8.0 s?
