A model of a helicopter rotor has four blades, each of length 3.1 m from the central shaft to the blade tip. The model is rotated in a wind tunnel at a rotational speed of 520 rev/min. Part A What is the linear speed of the blade tip? Express your answer in meters per second. Part B What is the radial acceleration of the blade tip expressed as a multiple of the acceleration of gravity, g? Express your answer as a multiple of g.

    A Sikorsky S-76C++ helicopter has four main rotors, each 6.71 meters in length, attached to a center shaft. NOTE: It is the end of each rotor that is attached to the shaft, like a blade on a fan. Each rotor weighs 3500.0 N and its mass is uniformly distributed along the length of the rotor. What torque is required by the motor to produce a start-up acceleration of 1.23 rad/s? HINT: Since the rotation is in a horizontal plane the...
