NE SD | What physics? I understand mechanical aspects very well but hydro and pneumatic not at all. Being a business major I have no reason to do all of that extra studying. At any rate, Michelin says their 1050 tires have a 730 square inch flat plate. If you take that 750 cart hauling 35,000lbs of grain plus it's own weight, roughly 10,000lbs, and divide that by 1460 you will get 30 psi. A far cry from his claims of 15psi above. Not to mention the fact that more of that pressure is placed underneath the sidewall than in the center of the tire. | |
