I have prepared this part(according to your dimensions) and applied steel material which has a density of 7850 kg/s2. Then I found mass moment of inertia(As you can see from image).

I used solidworks software to find mass moment of inertia, so that you can have good idea about this problem.

I hope this solution would help you to clear your doubts.

If you have any queries regarding this solution Let me know in comment section.

Good luck and Thanks.
