I Conditions of collapsing a container

AI Thread Summary
A discussion centers on the structural integrity of a steel pipe with an inner radius of 1.08 meters and outer radius of 1.1 meters under a pressure differential of 1 millibar inside and 1 bar outside. The primary concern is whether the pipe can withstand this pressure difference and what reinforcements might be necessary if it cannot. Participants suggest looking into existing materials and equations related to pipe collapse calculations for guidance. Resources are shared to aid in understanding the necessary calculations. The conversation emphasizes the importance of structural analysis in engineering applications.

Hello, I have some sort of problem which I would like to explore. We have yet to touch it in the class in the university, but it seemed like a crazy idea when i stumbled upon it.

Let there be a very long pipe with an inner radius of 1.08 meters and outer radius of 1.1 meters. The material of the pipe is steel. Inside the pipe there is 1 millibar of pressure while on the outside 1 bar of pressure. Would the container withstand the pressure difference? If not, what would it take to reinforce the steel to as such that it would withstand this pressure difference?

If calculations and equations can be provided, that'd be great.

Hello Dark one, :welcome:

Planning something like this ?

Lots of material on http://www.ogj.com/articles/print/volume-93/issue-15/in-this-issue/production/equations-shorten-pipe-collapse-calculations.html

Essentially something like that, yes.
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
