The housing of the electric motor is freely pivoted about the horizontal x-axis, which passes through the mass center G of the rotor. If the motor is turning at the constant rate Φ˙ = p, determine the angular acceleration Ψ¨ which will result from the application of the moment M about the vertical shaft if γ˙ = Ψ˙ = 0. The mass of the frame and housing is considered negligible compared with the mass m of the rotor. The radius of gyration of the rotor about the z-axis is k_z and that about the x-axis is k_x.
