Rotations of a rigid body close to the lagrange case under theaction of nonstationary perturbation torque

Abstract

The motion of a rigid body about a fixed point is one of the important problems in mechanics. In dynamics of a rigid body with a fixed point there exists vast bibliography on the perturbed motions.close to Lagrange top.and on the applications in the problems of flying vehicle entry into the atmosphere.rotating projectile motion and gyroscopy.
