Why do ships float?
Curiously question can float as the huge steel boat in water. Good, response was Archimedes Principle. This says that any object immersed in a fluid (the liquid gas) will experience a pushing force (upwards) equal to the volume of liquid displaced. This principle clearly explains why large ships can float on water: thanks to the thrust force due to the large volume of water displaced.
Even so, The boat design is very important.
It represents the volume space of an object. A higher volume, greater the water travels, and therefore, more thrust make it. If a steel bucket plunges 1 Kg in water, This would sink, since the pushing force is insufficient to keep it afloat. But if the same amount of steel is molded to form a longer figure, displace more water, You will have greater thrust of this, and therefore will float.
When designing a ship must take into account that the weight thereof is equal to the volume of water displaced. If your weight was greater than the volume displaced, the pushing force received serious enough to keep them afloat.
