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

726 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?

Things get crushed when external pressure is more than internal pressure + structure strength AND there’s no other way for the external force to get inside (read: air/water tight)

If the external pressure can force itself inside through a breach it will do that first as that is easier/less resistant. Eventually the pressure will equalize and there’s no more risk of crushing.

The titanic was filling up with water and had a rather massive breach, which became even bigger when it split in half. Water would have rushed into every opening available, equalizing the pressure very quickly.

The only things getting crushed now would be the metal itself and other structures, but there’s only so much those things can shrink.
