Hello, I was wondering if the moment of inertia of a 2-D triangle about its center of mass depends on the actual mass of the triangle. Formulas that I have found say that I = (bh^3)/36. Does this mean that the moment of inertia of triangles with the same dimensions will be the same about their center of mass regardless of their actual mass? I know that if you were taking the moment of Inertia about an arbitrary axis then the mass would come into play, according to the parallel axis theorem, but I'm not so sure about it when the inertia is about the center of mass. Any help clearing this matter up for me would be appreciated.
