tire stresses

It is better if you send yours and we can have a look if they are ok.

Guest: Many years ago there was a college text book on Strength of Materials by a 'Timoshenko' that dealt with odd shaped vessels etc. The formulas can be derived from the generalized dimensions of a torus and then applied to a specific torus. If you have done your homework meticulously you can submit them to this committee (CR4Forum) for examination and critiquing.

Since a torus is a double curved surface you have your work cut out for you.

Yes Stirling Stan, please I'd like to be one of that CR4 forum committee for examination and critiquing of Mr. Guest.

Wholeheartedly Second your volunteering!

Welcome to the critique committee along with all other readers and posters to this thread. SS

I'll be gratefull with you if you like take a look of mi work but..How to submitt the formulas develop, could be in a hand written page ,scanned and sent? formulas results are shorter but deduction is some longer.

Pard,..you might be better off to communicate with Michelin, BF Goodrich, etc. and present your request to them. There is a tire catalog on several of the Emergency Vehicle Technician websites that can well demonstrate why certain tires, based on technical considerations, (weight, roll, stopping, starting, turning resistance, etc.). There is a Northern California Emergency Vehicle Technicians Association that has an excellent link to a very informative tire catalog that we have been using when we need to verify what tires should be on our fire and rescue units.

Good luck.

Thanks,but my doubts are theorical question for different purposes than tires like "the internal diameter of a tiretube becomes smaller or bigger when you inflate that?" in fact i am intested in some kind of bellows.Yesterday,i could find a site what sells you the standards for manufacture formulas for design.I am not going to try for that path.I'll see the way to write the equations here.Thanks again.
