Rotation of the body with movable internal masses around the center of mass on the rough plane

Abstract

We consider motion of a system consisting of a rigid body and internal movable masses on a rough surface. The possibility of rotation of the system around its center of mass because of the internal movable mass motion is investigated. To describe the friction between the body and the reference surface selected local Amonton–Coulomb law. To determine the distribution of the normal stress in the contact area between the body and the surface linear dynamically collaborative model is used. As examples we consider two configurations of internal masses: hard horizontal disk and two material points, moving parallel to the longitudinal axis of the body symmetry in the opposite way. Motions of the system analyzing for selected configurations.
