There is a legend about how Archimedes discovered his law.He served in the Syracusan king Heron II as an adviser on general matters.Tom produced a crown of gold taken from the treasury.Features more suspicious king instructed Archimedes to find out whether the wizard stole the gold and not added any stead in the less noble metal alloy.To solve the problem is allowed to weigh the crown, measure it, but in any case not to spoil the beauty.
Search and solve
task assigned Heron II, seemed insurmountable.Archimedes spent a lot of time to measure the individual elements of the crown, but constantly strayed from the account.Exhausted measurements and calculations, he went to the bath, and in that time have built up in Syracuse just one in which there were baths, to take water treatments.In one of these baths he plunged his mortal body and Archimedes.He was surprised by the fact that the immersion of the water began to flow over the edges.Once again he refilled the water to the upper level and slowly, trying not to spill it began a new dive.The water took him, and forced out of the shed outside.With a loud cry: "Eureka!" - Archimedes jumped out.He ran down the street, forgetting to throw over anything from clothes.People got used to the eccentricities of the great inventor, so all confused only cry, not the kind of Archimedes.Using a measuring cup, a researcher can easily calculate the volume of the crown, and knowing the density and weight of gold, defined the amount of metal, eaten in secret is a jeweler.Fast court ruled in favor of Archimedes, goldsmith executed a warning to others.
experiments with floating ship models
Opening displaced volume has not yet led to the theory of diving bodies.Archimedes' principle was clearly formulated only after a series of experiments in which established rule for all items immersed in water.For example, the stones did not rise to the surface, and dry pieces of wood were floating.They were built small models of vessels that were placed in a bath.On deck models shipped various items.Observations were carried out continuously.As a result, it was found that when loading a small boat can be achieved in order to remain afloat.Archimedes explained and overload the ship.It displaces more fluid, which keeps it.
law of Archimedes.Experiments with real ships
inquisitive inventor of the models moved to the real ships that were built on a small shipyard in Syracuse.In those days there were already small sailing vessels, they pledged to enhance stability ballast.Sometimes it is placed so that the ship began to sink.Through trial and error ship builders for each new ship to select the optimal settings.Here help the talented inventor was quite relevant, shipbuilders was described Archimedes, swimming body has now become the practice of science.There is evidence that Archimedes was offered a number of interesting designs for warships to sink the enemy in frontal and side crashes.Particular attention was paid to the shopping gallery.These ships made a long voyage across the Mediterranean Sea.They had to transport large quantities of goods, so the proper placement of the goods contributed to a better use of space.It helped calculations and calculations of the inventor, in which Archimedes used.Hydraulic dynamic movement of loaded vessel is now based on precise calculations.
Other applications Archimedes
Aeronautics, which arose at the turn of XVIII-XIX centuries, it turns out, is subject to human reasoning, who lived from 287 by 212 BC.e.Archimedes' principle for the balloon, balloons and balloons is mainly due to the possibility of man to take off due to knowledge.Hoping to lift for aircraft, aeronauts (so-called lovers of flying on such devices) define the scope of its aircraft.Currently, the feast of Aeronautics held periodically in different cities of Russia and abroad.Flying hot air balloon is admired by viewers even greater range of sensations obtained by the participants of the flight.
