The precessional angular velocity is given by \(\omega_{P} = \frac{rMg}{I \omega}\), where r is the distance from the pivot to the center of mass of the gyroscope, I is the moment of inertia of the gyroscope’s spinning disk, M is its mass, and \(\omega\) is the angular frequency of the gyroscope disk.
