Towards a Prototype of a Spherical Tippe Top by M. C. Ciocci, B. Malengier, B. Langerock, B. Grimonprez

“…The commonly used simplified mathematical model for the tippe top is a sphere whose mass distribution is axially but not spherically symmetric, spinning on a flat surface subject to a small friction force that is due to sliding. Three main different dynamical behaviours are distinguished: tipping, nontipping, hanging, that is, the top rises but converges to an intermediate state instead of rising all the way to the vertical state. …”
