A cylinder is given initial spin around its z axes. Clicking on the perturbe button causes initial spin to
be given around the xaxis. The space and body cones are visualized. Euler 3D equations for zero torque
are solved analytically for this simplified special case where .
Implementation follows theory explained on pages 114115, in space dynamics book, by
William Thomson, 1961. Both retrograde (when ) and direct precession ()
can be visualized Different options are available to help analyze the dynamics of the system
