I'll see if I cant pull up another article that does a better job of explaining the torsional effect on the wheel. I thought the article was crystal clear even though the premise was wheelchair optimization.
Sure, their FEM was valid; I just didn't see where they clearly explained how the spokes and rim work together. More specifically, I was hoping to see a discussion of whether thinner spokes redistributed the load more effectively, resulting in better fatigue life.
