I asked GPT to take a second look at the part where it said "*dIx = dm * y^2*". I did NOT say it was wrong or it had made an error of any kind, I just asked it to look at it, but nevertheless it knew it had made a boo-boo. GPT said this: *"GPT: I apologize for the error in my previous response. The correct expression for the moment of inertia of a small volume element relative to the x-axis is:dIx = dm * (y^2 + z^2)This takes into account the fact that the mass element is not necessarily located on the y-axis, but rather at a distance y from the x-axis and at a distance z from the z-axis. Similarly, the moment of inertia of a small volume element relative to the y-axis is:dIy = dm * (x^2 + z^2) and the moment of inertia of a small volume element relative to the z-axis is:dIz = dm * (x^2 + y^2)I hope this clarifies the issue. Thank you for bringing it to my attention."* By the way, the version of GPT I was using was NOT the one that had the Mathematica plug-in.
