Detailed study requires complicated model » Flexibility » Rotor dynamics … Simpler study requires » 6 DOF (3 translational + 3 rotational) » Non-linear, coupled, ODEs Even simpler, by considering » Static stability : instantaneqous tendency of a body to return to its equilibrium. » Dynamic stability : enventually returning to ….
