SUMMARY
The discussion centers on the calculation of principal moments of inertia for a discrete set of mass points on a plane. The original poster expressed confusion over consistently obtaining a diagonal matrix for the inertia tensor when selecting a mass point as the origin. After community input, the poster resolved their misunderstanding, indicating that the approach was indeed correct. This highlights the importance of understanding the properties of inertia tensors in relation to mass point configurations.
