Archimedes Principle

Archimedes PrincipleArchimedes Principle is the apparent loss in weight of a bod... More is the apparent loss in weight of a body immersed in a fluid is equal to the weight of the displaced fluid.

Archimedes was acknowledged as the greatest scientist and Mathematician of ancient Greece. When Hieron, King of Syracuse, became suspicious that his new crown was not made entirely of pure gold, he summoned Archimedes to make the determination without damaging the crown. Perplexed at first, Archimedes stumbled upon the solution one day while taking a bath. Noting how the water level increased when he immersed himself, Archimedes immersed the crown and measured the increase in water level it caused. He repeated the same procedure using an equal weight of pure gold, and noted that the water level did not increase as much. The unscrupulous goldsmith had substituted some less dense, and less expensive, silver for gold in the crown. The legend has it that Archimedes was so excited by his discovery that he sprang from the bath and ran naked through the streets to the palace, shouting “EurekaEureka is an exclamation of satisfaction on discovering some...!” meaning “I have found it!”. Ever since, that exclamation has been regarded as an appropriate way to announce a startling discovery.

Archimedes principleArchimedes Principle is the apparent loss in weight of a bod... More states that: ‘Any object, completely or partially submerged in a fluid is buoyed (lifted up) by a forceIn physics, a force is any influence that causes a free body... which is called buoyant and is equal to the weight of the displaced fluid’.
