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

Question

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?

Answer 1

Things underwater get crushed when they are sealed and there is a pressure difference between the sealed interior and the exterior. Most (all) of the compartments and rooms and spaces on the titanic have been compromised and filled with sea water years ago so there are no pressure differentials anywhere.
