The study of the motion of a gyroscope without rotational symmetry

IOP Conference Series: Materials Science and Engineering, 2019
Abstract In rigid dynamics theory the gyroscope has a special role, as one of the bodies with the most complex motion, having three degrees of freedom. As consequence of the complexity of the motion is the fact that only for three situations, the equations of motion can be analytically integrated.
