two identical rings a and b are acts upon by torques τa τ a and τb τ b respectively. a is rotating about an axis passing through the center of mass and perpendicular to the plane of the ring. b is rotating about a chord at a distance 12√ 2 1 times the radius from the center of the ring. if the angular acceleration of the rings is the same then

The system rotates around an axis in the plane of the figure that passes through its center .
a) Find the moment of inertia concerning this axis.
b ) Find the I for an axis parallel to the previous one passing through the masses.
c) Find the I concerning an axis .... inner radius a and external b
