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

Equal pressure both sides of the steel plates. Submarines crush until the pressure equalises both sides of the structure.
