First we must convert RPM to angular speed:
Now we use the relationship between tangential and angular speeds:
Next we use the definition of centripetal acceleration:
This amount in terms of g results:

Helicopter blades withstand tremendous stresses. In addition to supporting the weight of the helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip.

Let us treat a helicopter rotor blade as a long thin rod, as shown in the figure. (Figure 1) . 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 5.9 rev/s in 10 s ?
