weighing tons to cargo ships You may be surprised to learn that they survived despite the addition of tons of cargo. or the major to physics concepts If you are not a judge, you may accept without knowing the background. everyone ‘huhwill be an expertThere is of course no rule.

still like that confusing We try to explain to you the situations that can occur in the simplest way. We’ve written an enlightening article on the fact that parrots can talk, although monkeys, previously thought to be closer to humans, cannot talk. How are your ships now? above the water We tell you you can stay.

If you throw a small nail in the water, it sinks, how can large ships float? We found the answer thousands of years ago:

• fragmentary fish

Let’s tell the story of this briefly. king of ancient Greece II. hierofamous mathematician and physicist from Archimedes He wanted him to build a huge ship. Known as the Titanic from ancient times, this ship was given the same name as the Italian city of Syracuse, which was then incorporated into the empire.

The ship in question had to be big enough to have a hot water supply. bathThere would be enough space for a library and large sculptures. As if that wasn’t enough, the ship in question, cargo could wear. We are not talking about a few animals or hundreds of kilograms of material here.

It was the wish that tons of materials could be transported by ship:

400 tons of grain, 74 tons of drinking water, 600 tons of silk and many more materials of this magnitude would be carried on this ship. In addition, many passengers, soldiers and even horse would also be included.

Even if you were a leading scholar of the time, the last thing you would want to do is upset the king:

Archimedes was also aware of this, so he designed a ship of this size and capacity. how to float makes you think. As he thinks about it, he is thought to be in a bath, in a bath. Our scholar, seeing that he felt lighter as he entered the water and that the water level rose, was then excited and the events at this point were famous. Evreka I think it’s related to his story.

If you don’t know that story, we’ve told it briefly here. Although the place they are connected to is the same, historians’ debates continue:

This confusion comes from the Greek word meaning keel. Kornē It is thought to have originated by mixing Corona with Corona, meaning crown.

Now let’s go back to our ship. How does this big thing swim?

This is exactly what Archimedes found:An object submerged in water as much as the weight of the water carried buoyant force is applied” In other words, if the weight of the object you place in the water is less than the weight of the water it displaces, the water will lift the object easily.

If you have a 5-pound object in your hand and that object moves (or moves) exactly the equivalent of 5 kilograms of water, it is at the slip point:

In this context, the object floating. However, if your 5 kg object only occupies an amount of water equivalent to 3 kg, the force exerted by the water is not enough to support this object, and therefore the object is sinks.

Here we use density. If you divide the mass of an object by its volume, you will find its density. Let’s move on to examples of nails and ships:

in the nails no spaces. They are completely made of steel. If you drop it in the water, it will increase in proportion to their weight, so they can swim. of gravitymust not exceed the lifting force. But one on the nail The buoyant force exerted is less than its own weight. Therefore, gravity (or weight) prevails and the nail sinks.

If we didn’t leave room in the ships and they were just huge piles of metal, they would suffer the same fate as nails:

But ships have air holes. Very large volumes They take the place of a large amount of water, but thanks to these air gaps, their weight is greater than the weight of the amount of water they hold. does not pass. When the ships crash, these holes get bigger as they are filled with water. they sink.

In other words, if a 1500-ton ship replaced 1000 tons of water, it would have an buoyancy force of 1000 tons. However, the ship Weight of 500 tons the ship would sink. For this reason, ships are designed with attention to this Archimedes principle.

Ships can carry more cargo by moving more water:

More for this they sink we can say. Gymnastics line The markings, the so-called “mandatory” signs on cargo ships, show how far the ship can be sunk while loading the cargo. Roughly speaking, the more it sinks, the more water it displaces. with more lift means to confront. However, this sign is used because different types of water have different buoyancy. If these safety lines are breached, the ship threatens to sink.

This too vital importance Today it is on every cargo ship as a safety measure. Different letters and lines on it show how much cargo can be carried in different seasons and types of water (fresh, tropical, salty).
