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. (a) Calculate the centripetal
acceleration, in m/s2, at the tip of a 4.30-meter-long helicopter
blade that rotates at 315 rev/min. 4679 Correct: Your answer is
correct. m/s2 (b) Compare the tangential speed of the tip with the
speed of sound (taken to be 340 m/s on this day).
