One of my work leaders has a saying that I think provides good insight in to how design/analysis should be conducted: "All models are wrong. Some models are useful."
I often tell my kids to "Do the math. If it works in theory, it might work in reality. If it doesn't work in theory, it probably won't work in reality"

Really like what this guy said.

I realize that axle loading can be a complex equation if you add the cantilever load, maybe some thrust loading, maybe even some torsional resonance (which can destroy systems). Actually, each axle sees different loading based on where on the 'bot it is. Not what I was talking about.

The equation for a churro in torsion has already been posted. That's the math that this thread started out talking about. Other posters have already shown with math that they don't take torsion well.

Simpler math that we can teach kids. So they can learn STEM, not trial and error.
