Why the ship does not sink even if the pin made of iron sinks in water?

 

You float in the water. It will sink. But why? Many will say that it is made of iron, so it will sink in water. If things made of iron sink in water, why does not a ship made of iron sink? Stuck on a question? So today I will discuss this topic. Even if the ship is made of iron, it sinks in water - this will be discussed with the explanation of science. So without further ado, let's get started.

1. Who floats in the water?

Come firstly about who swims in the water. We certainly know the density of water. The density of pure water is 1000 kg per cubic meter. So that's density, what's the benefit of knowing it? There is profit. Whether something floats or sinks in water can be determined primarily by density. Basically buoyancy is controlled by submersion or floating motion.

But we discuss density on 2nd. If you put an object in water with a density less than 1000, it will not sink. It will float on water. And if an object is placed in water with a density equal to the density of water, then wherever the object is placed in the water, the object will remain there, neither sinking nor floating. However, if the object's density is greater than 1000, the object will sink.

2. What is buoyancy?

So since iron has a density greater than 1000, it should naturally decrease. We see this in the case of pin made of iron. That pin drowned in the water. But why doesn't a ship of the same density sink?

This is where the flood game comes into play. What is buoyancy? When an object is in water, it exerts a downward force equal to its weight. Water also exerts an upward force. This upward force of water is buoyancy.

Buoyancy is mainly controlled by this sinking or floating. But how? Let's see.

You will understand when you get on the ship. As the ship begins to move, you will see the water on both sides of the ship moving backwards. As this water moves, the ship moves forward.

In this case, remember 3 things. If an object is able to displace water while in water, i.e. it displaces water to take its place, then that water is called displaced water. The weight of this displaced water will be an upward force on the object, known as buoyancy.

3. Drowning due to buoyancy

So 1. of 3 topics are drowning. If the weight of the object is greater than the buoyancy or the weight of the displaced water, the object will sink. Because the weight of the object acts downward. And the flow goes up. Since an object cannot displace an amount of water equal to its weight, the resulting force will be downward. As a result, he drowns in water. It can be seen in the case of pin made of iron.

4. Buoyancy is the movement of an object anywhere in water

Secondly the fact is that the object will stay anywhere in the water. This occurs when the weight of the object and the weight of the displaced water equalize. Meanwhile, the downward force and the upward force cancel each other out. So the net force will be zero. So wherever the object is in the water, it will not float or sink. This method is applied to submarines at sea.

5. Floating in water due to buoyancy

The last thing is to stay afloat. If the object's weight is less than this buoyant force or the weight of the displaced water, the object will float. Since the mass of the object is less than the mass of the displaced water, the net force will be upward. In this case, if an object is submerged in exactly as much water as the object's weight is displaced, only that amount will sink into the water. And the rest will float on water. We see this in the case of ships moving on water.

So you have to understand that whether something sinks or floats in water, it doesn't matter what the object is made of. One thing to worry about is how much water the object will displace while in the water. In short, buoyancy is the main reason objects float or sink in water.
