Archimedes Principle:

All about Archimedes and his principle

Archimedes was a great mathematician born in Syracuse, Sicily, Italy in 287 BC. He was an outstanding ancient Greek mathematician. His father, Phidias was an astronomer and mathematician. His family was quite well off. Archimedes has travelled to Alexandria, Egypt for his formal education. Upon completing his studies, he came back to Syracuse to help with his family and to work for King Hiero II as an engineer. His fame came from his relationship with King Hiero. He spent most of his time trying to solve problems for the king. His most popular solution was in regards to the golden crown. King was worried that the goldsmith who was making the crown was replacing some of the gold with another metal. He called upon Archimedes to find a way to see if the crown was made of pure gold or some metal also has been used. Archimedes came upon the solution on how to prove this as he was taking a bath. After entering a full tub of water, he noticed that the weight of his body displaced a certain amount of water. Knowing that the same principle could be used on the crown, he forgot himself with excitement. He jumped out of the tub and ran without clothes through the town, yelling ‘Eureka, Eureka’. He died at the age of 75.

Archimedes’ principle: –

He discovered the physical law of buoyancy, which is known as Archimedes’ principle. It states that anybody completely or partially deluged in a fluid at rest is acted upon by an upward or buoyant force. The magnitude of the force is equivalent to the weight of the displaced fluid. The volume of displaced fluid is equal to the volume of an object submerged in a fluid or to that small section of the volume below the surface for an object partially immersed in a liquid.
