Archimedes' principle states that a solid body immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. In other words, if the weight of the water displaced is less than the weight of the object, the object will sink. If not, the object will float, with the weight of the displaced water equal to the weight of the object.
One of his well-known inventions was the Archimedes’ screw. This device had a revolving screw-shaped blade inside a cylinder, and it could be turned by hand or by a windmill. This device is still used today for pumping liquids and granulated solids such as grain and coal. In some developing nations, this device is often used for irrigating agricultural fields.
The Archimedes claw was another of Archimedes' inventions. It was a weapon designed to defend the city of Syracuse and was also known as the "ship shaker." The claw consisted of a crane-like arm from which a metal grappling hook was suspended.Learn More
