The sum of the moments acting on a 3-D rigid body about its center of mass G is

The figures below demonstrate that it is possible to suspend a a rapidly spinning wheel with a string attached to one end of its horizontal axle. Find the angular velocity Ω  (i.e., precession rate in rad/sec) of the wheel with mass m= Kg spinning at a constant rate of p= rad/sec. The wheel is located at  d=0. m and its moments of inertia are Ixx=Izz=0.25 Kg.m2 and Iyy=0. Kg.m2. Use g=9.81 m/sec2 if needed.      

If a rigid body rotates about the z-axis, then its angular momentum vector
