is it possible to tell which is under the most pressure a submarine at the bottom of the largest ocean or a shuttle in deep space, or even a good guess will do, popped in my head for some reason last night after watching star trek.

pressure on a space ship is from the inside out to stop explosion but as the air pressure would be at 1bar the load on the hull would be significantly less than the pressure exerted on the hull of a submarine that would have to withstand several tons of pressure to stop it from imploding.The shape of a sub is such that a cylinder can withhold the pressure better than almost any other shape.(other than a sphere) a space ship could theoretically be any shape if it was to only fly about in space with no gravitational pull on it or be subjected to re=entry flight.

The pressure exerted by a fluid (e.g. the atmosphere or the sea) is proportional to the height and the density.
For the shuttle in deep space it is the opposite to the submarine as outside is a lack of pressure, or a vacuum. Assuming the pressure in the shuttle is at atmospheric, then the pressure difference across the hull is 1 Atm.
For the submarine, it would only need to go to a depth of about 10m for the same pressure difference across the hull (although this time the pressure is higher outside the hull).
Any deeper than this and the pressure difference across the submarine hull is more than the space shuttle.

It is definitely the submarine. At the bottom of the Mariana trench which is the deepest point (11033m) in the ocean the pressure exerted by the water is over 1100 atmospheres.
To put this in perspective this is the equivalent of having over1 tonne of pressure for every square cm. The amazing thing is that humans in a submersible have been there and there is life down there.
The space shuttle won't even come close.

As a guess I would go with the submarine. There is more pressure on the outside than on the inside (due to the weight of the whole ocean on it), whereas a space shuttle has more pressure on the inside.

The shuttle has just shy of 1 atmosphere pushing out against an almost total vacuum. In the ocean the pressure at 4000 meters is almost 1/2 ton per sq cm. outside with the inside kept at 1 atmosphere (or else).

A spacecraft is designed to hold one atmosphere of pressure against a vacuum, a differential of only about 15psi. A submarine has to withstand the pressure of the sea from the outside, and that is a LOT higher than 15psi.
I'm reminded of a line from Futurama, when the ship is being dragged under the sea and the hull starts to creak. When asked how many atmospheres of pressure the hull can withstand, Professor Farnsworth replies: 'Well, it's a SPACEship, so I'd say anywhere from zero to one...'

The shuttle is under 1 atmosphere of pressure. A sub can have tons per square inch on it

i could wager no. For here motives (those are basically guesses in step with what's wise): An area shuttle is uncovered to an inner rigidity of a million bar absolute and an exterior rigidity of 0 bar absolute (it somewhat is not that intense a rigidity to stand up to) A submarine is uncovered to 3 million bar gauge rigidity for each 10 meters that it dives, in different words, by potential of the time it gets to one hundred meters, it already has approximately 10 bar acting on its hull. it somewhat is a lot of rigidity and its exterior to boot (that's worse). The hull could could desire to be designed against buckling. an area shuttle is uncovered to truly super g-forces while a submarine isn't (have you ever seen a sub-mariner strapped right into a seat it fairly is designed for even load distribution earlier a dive?) A submarine does not could desire to stand up to the severe temperatures of area (re-get right of entry to into environment, extemely warm on area closer to solar and somewhat chilly on area pointing faraway from solar) an area shuttle has to handle nuclear radiation from the solar (this radiation does not harm you or me with the aid of fact we've the earths magnetic field preserving us, in case you progression faraway from the earth the magnetic field turns into weaker) i've got faith this suggestions to be properly suited ( i could be a tad little bit of on the magnetic field of the earth preserving us against the radiation, yet i comprehend that radiation is probably going one among the justifications why an prolonged distance manned undertaking hasn't been tried yet) final yet not least, i don't think of sonar and a propeller will do you plenty good in area. Likewise i don't think of rocket propulsion will do you plenty good below water, whether you are able to desire to get the rockets to truly artwork, you will quickly be apologetic approximately it. it is with the aid of fact the rocket could be dealing with water resistance and the forces generated could in all probability rip off the wings of the shuttle.

More dense more pressure. Therefore as water is more dense the sub faces more pressure then the space shuttle.

It's the submarine.
