Archimedes principles.
Archimedes principles were formulated or discovered by one of the greatest scientist, inventor, physicist, mathematician and an astronomer of the history. His name: Archimedes of Syracuse. He was a Greek.
Archimedes was one of the powerful mathematicians of history with lots of discoveries. Such as the popular Archimedes principle, Archimedes screw, hydrostatics, lever, infinitesimals neuseis constructions and also the Anticipated modern days, Calculus and Analysis by including the concept of infinitesimals and the method of exhaustion
His name Archimedes of Syracuse means he was born into the city of Syracuse, at southern Italy. He lived for 75 years before he was killed during the second Punic war.
That is just a brief about the wonderful inventor and scientist. I will be more focused on Archimedes principles.
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
A brief explanation about Archimedes principle. Archimedes principle enables easy calculation of the weight of an object partially or fully immersed in a liquid.
The force of an object moving downwardly is directly proportional to its weight. While the upthrust or upward force on the object is the Archimedes principle.
Example: when two objects of the same size and weight are released from a tall building. If one is released into a pool of water and the second one is released on free ground. Definitely, the free ground will reach its destination before the one that is dropped in liquid.
Thus, if the force of the object is positive the object rises; if negative the object will fully sink if zero the object naturally float.
Taking some behavior of objects in liquid. When an iron padlock is dropped inside a liquid, it goes down beneath the liquid because the density of the padlock is greater than the liquid. So, the upthrust executed by the padlock is less than the weight of the padlock.
Another example of Archimedes principle applies to the weight of an object in a liquid which is lighter when it is in liquid compared to when out of the liquid.
For instance, hold a padlock in your hand an immerse the iron with your palm holding it under the water. You will realize the weight reduce while the volume of the water increases, which means the weight has been subjected to the upthrust of the liquid.
Extra-illustration is fishing. If you catch a fish with a fishing line. When pulling the line up to bring out the fish. The weight of the fish tends to increase when the fish is out of the water. If the weight of the fish is 4kg while in water and when removed it is 5kg. This means the loss of weight is equal to the volume of water.
5kg-6kg=1kg. So, 1kg worth of the volume of water which is 1000ml has reduced from the water.
I will go deeper in my next publication.
