KNOW WHY SHIPS FLOAT AND NAIL SINKS IN WATER !

There is a general phenomenon of nail sinking and ship sailing. Let's understand why this happens in the following article.

We already know that when a body's density is less than that of water, it floats. When the density of a body exceeds the density of water, the body sinks in the water. The weight of water expelled by a needle is less than the weight of the needle, thus it sinks. And an iron ship is designed in such a way that it can transport a great amount of water. The weight of the water displaced by the ship's submerged part is equal to the ship's weight, therefore it may float. A body floats in a liquid when the weight of the entire body equals the weight of the liquid displaced by the submerged component of the body, according to the law of flotation.

An iron nail sinks in water because its density is greater than that of water. However, a massive iron ship floats. This is due to the form of the object. The midsection of a ship is hollow. When the ship is submerged, its whole volume, including the hollow section, displaces water to make room for itself. The amount of water displaced is substantially larger than the iron ship's bulk. As a result, the ship floats, whereas a sheet of iron is compact and has no air voids. Iron has a higher density than water. The sheet's weight exceeds the weight of the water displaced by the sheet. It sinks as a result.

The ship's effective density (m/V) is smaller than the density of the water because it is constructed in such as way.

V is the ship's volume, and m is the ship's mass.

The density of the nail (as of iron) is substantially higher than that of water. As a result, it sinks quickly. As a result, according to Archimedes' principle, the upthrust is more than the ship's weight. The iron ship floats on water because of this.
