Question

The gyro rotor is spinning at the constant rate p = 100 rev/min relative to the x‐y‐z axes in the direction indicated. If the angle γ between the gimbal ring and horizontal X‐Y plane is made to increase at the rate of 4 rad/sec and if the unit is forced to precess about the vertical at the constant rate N = 20 rev/min, calculate the kinetic energy of the gyro when γ = 30°. The axial and transverse moments of inertia are I_zz = 5(10⁻³) lb‐ft‐sec² and I_xx = I_yy = 2.5(10⁻³) lb‐ft‐sec².
