According to Archimedes' principle, a body in fluid, wholly or partly submerged, experiences an upward force (buoyancy) which is equivalent to the weight of the fluid displaced. The ship has a shape which displaces more water than a block of steel and so experiences a greater upward force.
boyancy in the hull of the ship
The boat.
That is because the ship is not pure steel. There are also spaces with air in between. This reduces the average density. Now, if the ship gets a hole, and water fills the spaces instead of air, the ship will sink.
A solid steel block sinks in water because its density is greater than that of water. However, a steel ship is designed with a shape that allows it to displace enough water to create a buoyant force greater than its weight, allowing it to float. The overall density of the ship is less than that of water, allowing it to stay afloat.
Steel ships float on water because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, causing the ship to float. The shape of the ship also plays a role in its ability to displace water and stay afloat.
The ship has enough gas in it to keep it afloat.
small water displacment compared to ships size
I am pretty sure cruise ships are built in dry docks where they can be flooded to float the ships. This is something i saw on Discovery channel on tv. Once the ship is complete they can flood the dock to float the ship to the ocean.
A steel ship floats because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, allowing it to stay afloat.
Not as long as it's still in the shape of a block. But if you re-shape it into the shape of a cup ... whether round or rectangular ... it will float, because it displaces much more water than a block does. If your cup-shape is done artistically and with care, people may call it what it looks like ... a little "boat" or "ship". Those objects are usually made out of re-shaped blocks of steel.
An object will float if it has a density that is less than that of water. Or whatever liquid it is placed on. In the case of a ship, that includes not just the steel, but the entire ship - including air trapped inside the ship.
Steel ships float on water because their shape is designed to displace enough water to create a buoyant force that is greater than the weight of the ship. This buoyant force allows the ship to float despite the steel being denser than water.
