Question 1 Which rotor blades contribute to the moment
vec(M)_(()/(A))
felt by the system in response to this mixed-axis rotation? (If the moment corresponding to a blade is completely canceled by the moment from another blade, neither of them contributes to the net moment on the system.) E C D B Question 2 The helicopter shown above has its main rotor turning at a constant rate around a shaft aligned with the
z
axis, and the body of the helicopter is rolling around the
x
axis passing through the body. If there is no moment acting on the system, around which axis will the system rotationally accelerate? z (Yaw acceleration) The system will not experience any rotational acceleration, because there is no moment acting on it.
y
(Pitch acceleration)
x
(Roll acceleration)
