Record number: 1, Textual support number: 1 CONT
The instantaneous axis of rotation of a solid body cannot remain rigorously fixed inside the body if it oscillates in space, and vice-versa. The Poinsot movement consists in cones rolling on each other without slipping, the contact line being the rotation axis, which describes one cone in space and another inside the body. 1, record 1, English, - Poinsot%20movement
