Haha it gave me a headache as well. I will try to get a sample calc and post it.

I would just like to know if it is theoretically possible to use the lumped method I described and attempted to prove valid mathematically. My question is really regarding the validity of my proof, not my actually mass properties calculations. For the sake of this question one could really...

Thanks for the reply! I should have mentioned that I have a MATLAB script calculating mass properties, and have also used a spreadsheet calculation to double check. However, using the two different methods I describe above I have not been able to get the answers to match. I resorted to the...

Hi all, You can use superposition to add moments of inertia when they're calculated about the same center of gravity (cg), but let's say you calculate the moments of inertia of several elements of a system about one cg and then use the Parallel Axis Theorem to then reference the total moments...
