Why do ships built from steel float in water?
Answers:
ok.all of the above are correct , but i'l summarize it for you in a very simple and logical way.
-By Archimedes principal every object when immerced in water
displaces an equal mass of water.
-Due to the large amount of air pockets on the ship (due to its shape) there is buoyancy created but the question is how??
-Simple : Density = Mass / Volume , consider the overall mass of the ship and all the volume it it takes up including the air pockets we find that the density of ship will be much less than that of water and hence it floats (just like oil on water).
Because theres air space at the bottom of the boat is my guess.
The same reason anything floats. It displaces more weight in water than it's own weight. And actually part of the boat sinks or is underwater to achieve this.
If you put a large piece of metal with a lot of air inside into water it will float.
its to do with the weight size length and width and the air in the shp to thats wat i could come up with lol
physics, and displacement. see archimedies on google.
Displacement!
also because steel is waterproof
its called displacement.
pretty neat. you can make concrete float with the right displacement.
proven at Texas A&I every year with the concrete boat contest
there are tanks called ballasts full of air that keep the ship stable and afloat
The bulkheads are pockets of air. Air is lighter than water and so will cause an upward force to keep the boat afloat (look at me, I rhymed!) the bulkheads are seperated so that if one is ruptured, then the boat will still float.
Its all to do with Eureka! When the guy sat in the bath and displaced his own WEIGHT in water.
Therefore if a boat weighs 1 tonne and 1 metre cubed of water also weighs one tonne, the boat hull must be big enough to displace 1 cubic metre of water without sinking. In this example the hull should be at least 2m long x 1m wide by 0.6m high leaving 0.1 m above its "water line".
The hull of a boat is hollow so as long as the weight of the boat is spread over a greater volume than the water it displaces it will always float.
The Simplest answer:
The boat for its size (made out of whatever) weighs less than the same volume of water. If you made a solid steel ship it would sink (like concrete or any other heavier than water materials). It works the same with Helium balloons. The volume of helium is lighter than the same amount of air so it rises.
Pretty cool when you think about it that way-
Because the overall weight of the ship is less than the amount of water that it displaces. i.e. if a steel ship weighs 10,000 tonnes but takes up the volume of water equivalent to 20,000 tonnes it will float.

These guys probably explain it better than I can
The hull displaces more water by weight, than the weight of the ship. You could calculate the weight of the ship by figuring out the total volume of the ship that is below the water line. If you multiply this volume by the density of water, it will tell you how much the ship weighs on dry land.
bouyancy
Because they are hollow. Because the shape of the boat causes the steel to displace an amount of water that weighs more that the ship itself weighs.
by displacing more water then it weighs
Displacement
