Revisiting dissipative motion of a spinning heavy symmetric top and the rise of the top by friction

Abstract

The dissipative motion and the rise of a heavy symmetrical top with a hemispherical peg are studied. A model taking the fixed point of the top as the center of the peg is considered when the top completely slips and the rolling motion is ignored. This is different from existing models like Jellet's one. Jellett's model and pure slipping are compared for different tops for the rise of the top, and an experimental method to determine the better model is proposed.
