Friends who live by the sea or riverside are no strangers to the ship as a means of transportation. But for many small partners living in inland areas, things like taking a boat are particularly longing and full of expectations and yearning. However, in addition to this yearning, have you ever thought about such a question, how can a ship so big be able to float on the water?

Just like when we throw a small pebble into the water on weekdays, we will plunge into it and sink in, but how can a behemoth like a ship be able to sail on the water all the time? And why is there such a saying as a ship? The ships we see on weekdays seem to have no wheels at all.

In fact, more than 2,000 years ago, Archimedes once proposed the principle related to buoyancy. Just as the effects of forces are mutual, when pressure is exerted on the one hand, there is also a reaction force on the other. Just like when a huge ship sails on the water, although it will sink a little under the action of gravity, the sea water will also generate buoyancy and lift the ship up. Therefore, if the weight of the boat is particularly large, the depth of diving into the water will naturally be greater, and the gravity will be greater, but the buoyancy captured will be greater.

Over time, the ship is constantly improving. In fact, at the very beginning, when the ship came into being, it still had wheels. It's just that later shipbuilders installed the propeller directly to the stern part of the boat in order to increase the speed and improve the aesthetics, and it was still at the bottom. We can imagine the electric fan in our home. When we turn on the switch, the blades of the electric fan will keep fluctuating. The ship also benefits from the rotation of the propeller, thereby obtaining a thrust, and under the action of this thrust, the ship will continue to move forward.

It is not difficult to find out if you look closely, in fact, there will be a line on the ship. , and the position where this line appears is not particularly far from the water surface. If you are a sailor, you really know this line very well, because what this line represents is the range of the draft of the ship. If the draft is particularly deep, it means that the risk of travel will continue to increase.

Therefore, even if the ship is particularly large, it also has a corresponding numerical limit when carrying cargo. Just like a driver or a sailor on a ship, seeing that the waterline on the hull has exceeded the maximum value, it will adjust the cargo or people carried on the ship accordingly. This principle is like an overloaded car. If this amount is exceeded, a series of safety hazards will occur.
