Assume an axisymmetric spacecraft with a body- xed principal coordinate system b = {b1; b2; b3} is undergoing torque-free motion. the 3rd axis b3 is the symmetric axis, while izz = 500 kgm2 and ixx = iyy = 300 kgm2. the nutation angle θ between h and b3 is 10 deg. if the body spin rate ! z = 2rad=s, how long does it take for the body to precess a complete revolution about the momentum vector?
