a uniform helicopter rotor blade is 7.80 m long, has a mass of 110 kg, and is attached to the rotor axle by a single bolt. (a) what is the magnitude of the force on the bolt from the axle when the ro- tor is turning at 320 rev/min? (hint: for this calculation the blade can be considered to be a point mass at its center of mass. why?) (b) calculate the torque that must be applied to the rotor to bring it to full speed from rest in 6.70 s. ignore air resistance. (the blade cannot be considered to be a point mass for this calculation. why not? assume the mass distribution of a
