Question

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

*r* = 3.4 m*rpm* = 340 rpm

A) Calculate the centripetal acceleration at the tip of a 3.4 m long helicopter blade that rotates at 340 rev/min in m/s^{2}.

*a _{c}* =

B) Compare the linear speed of the tip with the speed of sound (taken to be 340 m/s). Give your answer in percent of the speed of sound.
