Resumen

For this problem, we obtain the possible permanent rotations, that is, the equilibria of the system. The stability of those permanent rotations is analyzed by means of the Energy-Casimir method. We are able to give necessary and sufficient conditions for some of the permanent rotations. The geometry of the gyrostat and the value of the gyrostatic moment are relevant in order to get stable permanent rotations. Moreover, it seems that the necessary conditions are also sufficient, but, however, this fact can only be proved partially.
