Why does the strength of a submarine hull have to be stronger than the hull of a ship?
because if a submarine goes under water to deep levels, it needs to hold against the air pressure. Yes the person said above.. They have to have a MUCH higher ability to withstand the pressure of the water pushing in against the hull of it.
If you want to float a barge by building a hull under it instead of using barrels how do you know how much your hull will float?
You calculate the volume of water displaced (volume of hull up to the waterline level), and multiply by the density of the water in which it will float.
How much pressure can a submarine withstand?
It's totally dependent on the hull type, material construction, and overall design, but in general, just before a submarine reaches crush depth is as much sea pressure as it can handle.
Why are submarines forbidden to sink beyond a limit?
The hull of the submarine will crush or give way if the pressure of the water is too much.
Are submarines streamlined?
Absolutely - the modern submarine's teardrop shaped hull is a direct result of R&D that eventually led to the design that virtually all modern submarines use today.Cigar shaped hulls are also used, but like the teardrop hull, they also taper to some extent at the aft portion of the hull, in the Engineering spaces. This is to provide better water flow over the aft control surfaces (rudder and stabilizers). Submarines travel underwater much the same as airplanes do in air, and it is no coincidence they have similar hull shapes.The result of the modern submarine hull shape allows it to go much faster underwater than it can on the surface (a lot faster). In the past (WWII, e.g.) submarines were essentially surface vessels that had a limited submergence capability, and as such, they were designed to run much faster on the surface than underwater. With the advent of Nuclear Power and hull design changes, the submarine was transformed into a weapons system that could quickly gain the tactical advantage over surface vessels by being able capitalize on the speed given by the hull design.
What happen if the hull of submarine ruptured?
All modern submarines are "dual hull" constructed. What you see on the surface is the outer hull, or "superstructure". The inner hull, where the main systems and crew are, is protected by the outer hull. Damage severity of either the outer or inner hulls depends on the boat's depth at the time. If deep enough, it doesn't take much damage to the hull, as sea pressure will be virtually unstoppable, even with the quick-reaction damage control skills of a submarine crew. However, if sea pressure isn't a factor and the flooding can be controlled, then it's possible to survive such a casualty. Again, it depends on the severity of the hull breach, and the depth at the time. Several modern submarines (my old boat included) have survived underwater collisions which produced severe damage.

What are pressure hulls on a submarine?
Submarines have 2 or more hulls - the superstructure, which is the visible external hull you see, and the inner pressure hull, which contains all the primary equipment and houses the crew. The space between the superstructure and the pressure hull is where the main ballast tanks are located, as well as line lockers, access/weapons hatches, etc. The pressure hull is where the crew lives and works (and keeps on working...). The primary reason there are 2 hulls is that the pressure hull, while optimally designed for maximum sea pressure resistance, isn't designed for optimum speed and maneuverability underwater. The superstructure, built over the pressure hull, streamlines the boat and compensates for this, making modern boats extremely fast and maneuverable underwater. The best analogy is a thermos bottle, which has an outer shell (the superstructure) that protects and insulates the inner thermal bottle (the pressure hull). The Russians are known to use a double-layered superstructure on their larger boats, the theory being to insulate the pressure hull from a torpedo attack. The problem with that theory is that modern torpedoes don't need much proximity to severely damage or sink submarine, and any significant damage
