Question

Where is archimedes law used in industries?

Answer 1

Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.[1] Archimedes' principle is a law of physics fundamental to fluid mechanics. 

Explanation:

While constructing ships, Archimedes' principle is followed, a large portion of the ships are kept hollow from inside that maintains their density less than the water density, hence the weight of the ship becomes less than the weight of the water displaced by it, and the buoyant force of magnitude equal to the displaced water exerts on the ship, and the ship floats on the surface of the water.

THIS IS ONE OF THE INDUSTRIAL USE, where ARCHIMEDES PRINCIPLE and LAW OF FLOTATION IS USED.
