Search and problem solving
The challenge posed by Heron II seemedintractable. Archimedes spent a lot of time to measure the individual elements of the crown, but he constantly lost count. Exhausted by measurements and calculations, he went to the bathhouse, and at that time in Syracuse they built just one in which there were baths to take water procedures. Archimedes plunged his mortal body into one of these baths. He was surprised by the fact that during the immersion of the water began to flow over the edges. He again refilled the water to the top level and slowly, trying not to spill it, began a new dive. Water took him, but part of it was crowded out and spilled outwards. With a loud cry: "Eureka!" - Archimedes jumped out. He ran down the street, forgetting to throw on himself something from the clothes. The people are accustomed to the eccentricities of the great inventor, so everyone was confused only by the cry, and not by the sight of Archimedes. Using the measured capacity, the researcher easily calculated the volume of the crown, and knowing the density of gold and the weight, determined the amount of metal hidden by the jeweler. The fast court decided the case in favor of Archimedes; the goldsmiths were executed for the edification of others.
Открытие вытесняемого объема еще не привело к the emergence of the theory of swimming tel. Archimedes' law was clearly formulated only after a series of experiments, as a result of which a rule was established for all objects immersed in water. For example, stones did not rise to the surface, and dry wood floated. Small models of ships were built, which were placed in the bath. On the decks of models we loaded various items. Observations were made constantly. As a result, it was found that when loading a small boat, you can ensure that it remains afloat. Archimedes' law explained and ship overload. It displaces more fluid, which holds it.
Archimedes Law. Experiments with real ships
Inquisitive inventor of the models moved toreal ships that were built at a small shipyard in Syracuse. In those days, small sailing ships had already appeared, in order to increase stability they laid ballast. Sometimes it was placed so much that the ship began to sink. By trial and error, ship builders for each new vessel selected optimal parameters. Here the help of a talented inventor turned out to be quite relevant, the lawmakers Archimedes was set forth to shipbuilders, and now the floating of bodies has turned from practice into science. There is evidence that Archimedes was proposed a number of interesting designs for warships to sink the enemy in frontal and side impacts. Special attention was paid to shopping galleries. These vessels made long voyages in the Mediterranean. They had to transport large volumes of goods, so the correct placement of the cargo contributed to a better use of space. It helped the calculations and calculations of the inventor, which used the law of Archimedes. The hydraulics of the dynamic movement of the loaded vessel is now based on accurate calculations.
Other applications of Archimedes Law
Aeronautics, originated at the turn of XVIII-XIXcenturies, it turns out, is subject to the conclusions of a man who lived from 287 to 212 BC. e. Archimedes' law for hot air balloons, balloons and balloons is basic, explaining a person's ability to take to the air at the expense of knowledge. Calculating lift force for aircraft, aeronautics (as fans call it on such devices) determine the volume of their aircraft. Currently, the festival of aeronautics is periodically held in different cities of Russia and abroad. The flight of hot air balloons is admired by the spectators, the flight participants themselves receive an even greater range of sensations.
