After we knew the purpose of establishing the ship and the importance of maritime transport in trade or tourism, and after the ship owner decided to build a ship the ship to be used for its commercial purpose, and after also meeting with the ship's designer an providing him with some information about it, let's talk about how the ship floats despite its large size and that most ships are made of steel, which is considered to be more dense much more than the density of water. But before we begin to understand the theory of buoyancy, we must understand what density is? And the definition of density is a unit mass sizes.
If a steel object is thrown into water, it is natural that
it will sink in water for two reasons, firstly because the density of steel is
greater than the density of Water and secondly, a solid body could not displace
an amount of water or a volume of water equal to its weight, but if this body
displaced .A volume of water equal to the volume of the submerged part, and
when the weight of this displaced volume of water displaced by the body is
equal to For the weight of the body itself and at the same time the volume of
displaced water must be less than the total volume of the body .The displaced
water is greater than the size of the body to sink the body, and we must know
that Archimedes' theory states that if a body is completely submerged, the sameOr,
in part, it will receive an upward thrust equal to the weight of the body.
