Two discs of moments of inertia `I_1` and `I_2` about their respective axes, rotating with angular frequencies, `omega_1` and `omega_2` respectively, are brought into contact face to face with their axes of rotation coincident. The angular frequency of the composite disc will be `A`.

Two discs of moments of inertia I_1 and I_2 about their respective axes normal to the disc and passing through the centre and rotating with angular speeds omega_1 and omega_2 are brought into contact face to face with their axes of rotation coinciding. Then the angular speed of the two disc system is
