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

Mouvement de nutation d’un anneau. Calcul de la fréquence de nutation d’un anneau plan libre [...] Nous sommes en présence d’un mouvement de Poinsot, car le moment au centre d’inertie des forces extérieures est nul. Nous connaissons le résultat établi en cours, à savoir : l'axe du gyroscope décrit un cône d’ouverture constante [thêta], le mouvement est périodique de période T [...] 2, record 1, French, - mouvement%20de%20Poinsot

Principe mécanique : La stabilisation par «SPIN» ou encore «raideur gyroscopique», repose sur le résultat capital du mouvement de Poinsot, qui indique que si la rotation du solide est portée par un axe principal d’inertie, cet axe restera fixe dans l'espace inertiel. Nous avons aussi montré que le mouvement libre est stable si cet axe est celui de plus grande inertie, notamment en présence de dissipations internes. 2, record 2, French, - axe%20principal%20d%27inertie
