The vessel “Harmony of the seas” is 362 m long, 66 m wide, 73 m high and 227,000 tons in weight. So how do the ships float? Why do ships remain on the water surface and not sink? Let's answer it now.
In fact, Archimedes gave the answer to this question an average of 2250 years ago. The answer to the question why the ship does not sink is “Lifting Force of Water”.
Let us summarize the situation by briefly explaining the 3 images shown in the picture above.
The ship is on the surface of the water. This is due to the fact that water pushes objects having a density less than its density to its surface. With the push force released due to density differences, the object floats to the surface. We can say that the weight of the object and the lifting force applied by the water are equal to each other.
2. If we look at the ship is not at the surface of the water nor at the bottom. The ship is suspended. If the object is of the same density as the water, the object will sink fully, but will not sink. Here too, the weight of the object and the buoyancy of the water are equal.
If we look at the 3rd sight, the ship seems to be submerged. Because the density of the object is more than water. The object continues to sink until it reaches the bottom. Here, the weight of the object is higher than the buoyancy applied by the water.
· The most effective factor here; density of water.
Ships are heavy vehicles due to their structure. However, they are designed to be less than the density of water so that they do not sink. Ships also; Because of its wide and hollow structure, the air in them is very high. The total density decreases considerably. In this way, it has a density less than the density of water. Because of these features, the ships can stand on the surface of the water before swimming.
If the vessel starts to receive water, water is introduced into the vessel instead of air. As the water will increase the total density of the ship, the ship sinks. That's why the ship that gets water sinks, the ship with air floating on the water surface, we can say that it does not sink.
Ships have a certain load carrying capacity. If the ships carry a load above this capacity, they may sink because their density will increase.
If we look at the ships, the color of the lower parts and the upper parts are generally not the same. The upper parts are in separate color. The reason of this; is to understand the ship's overload. If the color of the ship at the top is under water, there is an overload and there is a possibility of the ship sinking. Therefore it is recommended to load according to the capacity of the ship.
