mass moment of inertia of an irregular area
Hi. Please help. I'm struggling to find the mass moment of inertia of an area.
Please see picture.
I already have the centroid of the area, and the exact area.
How would I find the mass moment of inertia of this area about its centroid?
I tried using AutoCAD, but it gives you the *area* moment of inertia which isn't helpful to me?
do you guys know any programs that find the mass moment of inertia of an irregular area for you?
Thanks A LOT.

Alibre can do that. I think Solidworks or Pro-E can too, but not sure.

Pro-E and Solidworks will definitely do it. However, you could just start breaking it up into a lot of smaller parts and calculating it yourself. I would think setting a spreadsheet up wouldn't be too difficult, just time consuming.
