So if a container is not fully inflated, but contains more than 1 psi difference than the surrounding atmosphere, then it won't burst. Agreed?
There is "never" any difference, it's all immediately equalised. It's just a case of how much stress the walls of the container can resist an equal crush from all areas inside and out.
So a container with 15 psi in an environment of 0.01 psi will not burst because:
A. both the container and surrounding environment are now 15 psi.
or
B. both the container and surrounding environment are now 0.01 psi.
Which is it? *edit- upon further reading I guess it's A. Apparently enough air will come rushing in out of the .01 psi environment to create a 15 psi layer around the container.
Now about that truck tire. If it's a 100 psi tire inflated to 100 psi, the atmosphere is 14.7 psi, and they're 'equalized' as you claim, what is the psi of each one?
100 psi acting on the tyre alone. The air pressure will act against the vessel that took it, so it's equalised all the time and only the make up of the rubber and wire can determine when it breaches, because it's being crushed from all angles until the rubber "walls" starts to compress to a point of thinning out and the weakest point will be breached. allowing the air back into the atmosphere.
So both the inside of the tire and the outside atmosphere are now at 100 psi?
What if I have a truck tire with 100 psi next to a car tire with 30 psi? Let's say 1 cm away.
*edit- What keeps the 100 psi layer around one tire from spreading to the 30 psi layer around the other tire, or even the 14.7 psi area in between?
If there's air pressure inside the dome and vacuum outside, why doesn't it explode outward?
Because a dome is the strongest/ possible structure we can have to hold anything pressure wise.
The domes density is strongest at the bottom, just as a sky scrapers density is strongest at its foundation.
Domes and curved structures are able to sustain excessive pressure against the outer curve. A dome would hold back pressure from the outside, but would be unable to hold in as much pressure. Not to mention one made of ice.
Ever notice how most dams are curved toward the reservoir behind it or at least straight? Ever see one curved outward from the water?
Hold on, I think I might have just had an epiphany in what Scepti is trying to say, if I'm wrong just tell me because I'm not trying to twist your words around. It sounds like he is saying that a tire inflated to 100 psi has the same force both inside and outside acting on it. That the local atmospheric pressure on the container, i.e. the air directly in contact with the outside of the container, has increased to counter the pressure inside the container. Or maybe that the container expands and creates more surface area on the outside for the atmospheric pressure to work on. Am I getting close to your thinking Scepti?
Thank you lord , finally someone with logic.
Absolutely correct Duck.
I wondered the other day if this is what you were thinking of.
What happens when I drive away? How does the 30 psi layer surrounding my tire keep up?
