Modeling the Frictional Driving of a Gyroscope Casing by a Spinning Rotor

The rotation of the casing and rotor of a gyroscope is studied by considering frictional effects. Friction causes the casing to rotate, and over time, air dissipation and friction at the touchpoint gradually stop this rotation. Several models for air friction, friction between the rotor and casing, and friction at the touchpoint are analyzed. Fit results demonstrate that while some of these models can describe the primary motion, certain effects require further study to yield more precise results. These findings can aid in developing improved models for the rotation of satellites.

Effective potential of a spinning heavy symmetric top when magnitudes of conserved angular momenta are not equal

There are various types of motion of a heavy symmetric top like regular precession, cusp like motion, rise of the top, etc. One of the tools used to understand that motion is effective potential. The effective potential for a spinning heavy symmetric top is studied when magnitudes of conserved angular momenta are not equal to each other. The dependence of effective potential on conserved angular momenta is analyzed. This study shows that the minimum of effective potential goes to a constant derived from conserved angular momenta when one of the conserved angular momenta is greater than the other one, and it goes to infinity when the other one is greater. It also shows that the usage of strong or weak top separation does not work adequately in all cases.

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

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.
