quote:I really need to illustrate the compression in the tread and for the cases where there is slipping, show this. The only way I can think of doing this is accompanying the diagrams for each of my 3 cases with graphs. This will take time to do, but if it really helps I will do it. However, I cant help feeling that people should be convinced by my experimental result even if I have not drawn a picture
I definitely wish you would. So far you haven't provided any explanation as to why R=H. Your experiment is interesting, but I am more convinced by the fact that neither of us has been able to find anyone in the literature, anywhere, that has claimed R=H under any circumstances.
You say that my drawing of the loaded tire in Figure 1 can only be true if the tire had slipped. This drawing looks exactly like the one from your write-up that you used during your argument that R=H. But anyway, please draw a picture that shows what the loaded tire looks like if it doesn't slip. In order for R=H, the length of the contact region needs to be shorter than what I have shown in Figure 1. How does this happen?
