Hey guys, I need some help. I have an old fortran program that needs axial moment of inertia as well as polar moment of inertia.(adsbygoogle = window.adsbygoogle || []).push({});

I have the part in Unigraphics NX5.0, where I can get the mass, volume, radius of gyration, and moment of inertias about each axis. However, I cannot find where to get polar moment of inertia.

So, I guess I either need someone who knows how to get J in NX, or some sort of relationship between the values I have and polar moment of inertia. I don't really think there is a direct relationship, but I'm struggling.

Thanks a lot guys,
