The moment of inertia of a rod of mass

here,as the axis passes through the bisector of the angle between the rods,so

So,w.r.t the mentioned axis, the rods have a total moment of inertia of

Now,from perpendicular axis theorem, the moment of inertia of a ring of radius

So,w.r.t the given axis,the moment of inertia of the whole system is
