Let us treat a helicopter rotor blade as a long thin rod, as shown in the figure. (Figure 1). Figure 3.75 m- - Rotor 1 of 1 m = 135 kg
Y 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. Express your answer to two significant figures and include the appropriate units. Itotal= 1900 kg-m² Submit Previous Answers Correct Part B How much torque must the motor apply to bring the blades from rest up to a speed of 6.0 rev/s in 5.3 s? Express your answer to two significant figures and include the appropriate units. μA x Xb T= 7500 f O x-10" 4X N•m 2
