How do sunken ships like the titanic not get crushed under the pressure?

736 views

I assume the metal and materials the boats are made of are strong but surely not to withstand the pressure of being 12,000 feet underwater? At the end of the day it’s not like the engineers had to consider holding up to that much pressure in their design right?

Because the titanic doesn’t contain gases. Objects that are only composed of solids and liquids are almost unaffected by pressure.

They can be slightly affected if the pressure compresses some material more than other, but at the pressure of where the titanic is, the effect is negligible on any liquid or solid.

They can also be affected if a different crystal configuration is more stable at this pressure (like graphite to diamond), but they only happen at pressure a lot larger than that. Thousands of times larger for graphite to diamond, for example.

Also, all the posts you’ve seen about humans’ bodies being crushed at those depths are false. Humans would die if they were in water at those dephts because of the effects on gases in their lungs and blood, but their body will remain almost exactly the same as usual.
