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 ProE can too, but not sure.
