  x  Model










The figure above shows a cross section through our model of the top, which can be characterised by the radius r, and the distance a of the center of mass S from the center M of the sphere. If the top stands on its stem, the motion can be described by the analogous defined quantities r' and a' (a' is not shown in the figure).

The moments of inertia, which are essential to determine the rotation, are treated to be known.
