Question

Physics

A uniform helicopter rotor blade is 8.97 m long, has a mass of104 kg, and is attached to the rotor axle by a single bolt.(a) What is the magnitude of the force on the boltfrom the axle when the rotor is turning at 329 rev/min?(Hint: For this calculation the blade can be considered tobe a point mass at its center of mass. Why?) (b)Calculate the torque that must be applied to the rotor to bring itto full speed from rest in 7.68 s. Ignore air resistance. (Theblade cannot be considered to be a point mass for this calculation.Why not? Assume the mass distribution of a uniform thin rod.)(c) How much work does the torque do on the bladefor the blade to reach a speed of 329 rev/min?
