ON THE MOVEMENT OF A RIGID BODY WITH A RING SUPPORT AREA ALONG A ROUGH PLANE

Argatov I.I., Institute of Problems of Mechanical Engineering, St. Petersburg, Russia

Equations of plane-parallel sliding of a rigid body with the ring support under dry friction are derived. For the time of braking of a nonhomogeneous ring, we obtain a two-sided estimate which coincides with the "unimproved" estimate in the limit case of the narrow ring. As an example, the problem of braking of a system of two nearly situated narrow rings is considered.
