WebMay 26, 2005 · 2. Ok divide this problem into two parts . First find the moment of inertia of complete disc (without any part cut) about the origin. Now find MI of the cut out part about the origin using parallel axis theorem. For the second part , you will have to find out mass of cutout part,this can be easily done as the disc is uniform , use unitary method. WebMoment of inertia is a different concept.
