Archimedes: More than Just a ScrewJun 20, 2021
hello everyone, welcome back to a new episode of side projects. If you don't know, I have some channels. about
screwit's a video we put on side projects so hope you guys enjoy it let's jump if seen only determined intellect Archimedes may have reached great heights based solely on his majestic appearance sculptures and paintings depict a wise and contemplative face framed by an unruly white beard and everyone knows people with beards look smarter he also had a nearly hairless scalp which again I don't want to repeat but everyone knows smart people all over it's ours The brain pushing our hair through the venerable tinkerer and problem solver is not as well known as other ancient sages, credited with a number of impressive technological advances, many of which are still in use today.
I say that Archimedes is quite well known when Archimedes was born at the end of the 3rd century BC. C. The Sicilian city of Syracuse was a thriving center for commerce, science, and the arts as the talented and ever-curious son of a prominent local stargazer and mathematician. he was encouraged to pursue his interests early on, but surprisingly little is known about Archimedes when he was a child. His family is alleged to have been related to King Hero II, who reigned from 217 to 215 BC. Although these claims are subject to some disagreement, they would explain his close relationship with the king in later years by purging as much as he could from the local masters long before his fellow Archimedean students set out on a voyage of discovery to the famous Egyptian city. of Alexandria founded by Alexander the Great less than a decade before the counts of his time in Alexandria are few, but he may have studied under the famous mathematician Euclid, a man often referred to as the father of geometry . whether he did or not, the evidence suggests that Archimedes was influenced by Euclid's work and that he incorporated elements of it into his own upon returning to Syracuse from Alexandria.
Archimedes pursued a life of deep thought, practical invention, and imperial service. In fact, many of his inventions and breakthroughs. They were solutions to problems that the king himself hired him to solve, or so the stories say. Many of the tales associated with Archimedes contain elements of the dramatic and the comic, frankly absurd. According to historians, it is very likely that some of these were invented after his death to To add flair to some rather mundane subjects, Archimedes claims fame includes advances in mathematics and military technology, but he is most praised for his labor-saving
screw, according to legend, Hero King II was constantly bothered by rain and leaking water. unable to find a simple and effective solution, he turned to Archimedes for after weighing the problem carefully and discarding the
moretraditional methods of extraction, the inventor devised an ingenious contraption, the device consisted of in a screw or auger rotated about a central axis fitted snugly within a c larger cylinder, alternative methods used a hollow tube spirally wound around an axis which eliminated the need for an outer cylinder.
Early examples were made of wood, while later ones were constructed of metal. The latter were heavier and more durable, but rudimentary mythology techniques meant that manufacturing was expensive and quite laborious; however, they were relatively portable and could be used in a variety of applications regardless of design, one end plunged into the offending water while the other rose above it at an angle of approximately 45 degrees on the upper side, a worker or workers would turn a handle, rotating screw or tube swallowed water intermittently and transmitted it upward with each successive turn with continuous cra Thinking it wasn't long before a steady stream shot from the top until only trace amounts remained in the pool below, artists' renderings show man-sized devices with diameters greater than a foot that would have been capable of moving large amounts of water with relative ease. the simple but efficient machine worked amazingly well, and so well, in fact, that it is still in use today.
Archimedean screws are usually powered by diesel engines for stormwater and flood management applications, but in some developing countries they are often still hand-driven and used in agriculture by contemporary standards, it seems strange for a king to care for such petty concerns as standing water in the hulls of ships, but it's an interesting story. Another story involving Archimedes and the hero is based on a new crown that the king commissioned. from a local craftsman according to legend the hero allocated a fixed amount of solid gold for the project it was weighed beforehand and when the finished product was presented it was exactly the same weight the story could end there but the cautious king realized that the craftsmen could have substituted some of the gold for cheaper silver and pocketed the difference Archimedes had the task of determining whether or not he had been built, the situation perplexed his cunning mind and after considering the riddle from nearly all angles, I was nowhere near done with it.
Then, after a long day of contemplation, the weary thinker slipped into a public bath to soothe his frazzled nerves as his feet, legs, and torso were submerged. He noticed that the volume of water cascading over the edge of the tub was increasing. Tina assumed that she could accurately discern the density of the crown by submerging it and measuring the water it displaced since she already knew the weight of the crown and could easily determine its volume, determining its density and therefore purity would require only relatively easy calculations. silver is less dense and therefore lighter than gold and gold that has been adulterated with silver will displace more water than solid gold of the same weight it is stated on this revelation
archimedesjumped out of the bath and ran naked into the street yelling eureka eureka either i found it i found it ironically in the story there is no mention if the craftsman was guilty or not if the story is true then there are two likely outcomes if i hadn't done anything clandestine i could have lived the rest of the days in a lavatory faithful to a grateful king, by contrast, the punishment for theft may have been banishment, imprisonment, or you guessed it, execution in any manner, an end to al some kind it would have been nice and whether this is
justa story or actually happens we just don't know, while many of Archimedean's inventions dealt with benign problems like royal crowns and stagnant seawater, others were more of a more serious nature.
Bellicose due to its strategic location and commercial power, Sicily was constantly on the front lines of geopolitical events in the region caught in a massive tug of war between Rome and Carthage. The threat of invasion perpetually lurked on the horizon during the reign of Hero II. not one to sit back and wait for nature to take its course the hero employed
archimedesto bolster the island's defenses archimedes' work included strengthening the fortress walls and building innovative war machines the likes of which the world had never seen soon after, when a rogue faction within the government openly declared its allegiance to Carthage, embittered Roman politicians and the military commanders began to accumulate forces for the inevitable attack that later, in the first years of the second century a. the island of sicily and although the defenders were unable to permanently prevent the invaders many of Archimedes' inventions were used with some success it is often claimed that the catapult was one of the inventor's designs but there were other more dramatic ones such as the claw which consisted of in a giant iron claw connected to a chain and beam hidden behind the wall of a coastal position, though specific measurements of size and weight appear to have disappeared over time, accounts and drawings suggest the implements were at least as tall as ships and weighed many tons.
The immense bulk and gravity of the claw did much of the work, but only after they were hoisted into position by large pulleys and stout men do some accounts claim that the colossal device grabbed the bottoms of approaching ships and capsized them. , while others say that he dove from above bringing down the rig and superstructure before sending the ill-fated ships to the bottom of the sea in quite dramatic fashion. As impressive and effective as these devices could have been his Archimedes like burning mirrors though that supposedly took things to another level constrained by scarce resources and inadequate manpower Archimedes did what he did best by devising ingenious ways to protect his island home to use a modern term archimedes was certainly thinking outside the box legend has it that before the invasion he invented a method of focusing sunlight using mirrors and when the conditions were right the results were nothing short of spectacular , as anyone who has burned a blade with a magnifying glass knows that it doesn't take much to make a fire in a much larger one.
Apparently, the Archimedean-scale system was capable of destroying enemy ships on the high seas. Reports of ships exploding and burning abound, though it's fun to imagine, and it's theoretically possible to burn wooden ships to ashes using concentrated sunlight. However, it is highly impractical even by 21st century standards. the legend persists but even if it is true it was not enough because the island finally fell after a two year siege over the years the legend of the burning mirror caught the attention of various scientists, historians and adventurers who tried to prove or to discredit everything once and for all in the early 1970s, a Greek team conducted an experiment during which dozens of sailors reflected the sun's rays with oblong mirrors almost five feet long on a wooden boat covered with of tar 150 feet away, the boat apparently caught fire fairly quickly, but another experiment by the crew of the TV show Mythbusters nearly four decades later had quite different results.
They used 500 volunteers aiming 500 mirrors, all of which had almost no effect on a harmless boat shelling peacefully in the distance. powerful technology they couldn't compete against in any case, it seems unlikely that Archimedes' laser-like invention Built with primitive mirrors, it sent many enemy ships into the murky depths, though many of them aren't exactly to read some of Archimedes, as the lesser known advancements and inventions have had the greatest impact on modern society. It is said that he created the world's first odometer. Archimedes also did innovative work with pulleys and levers using a wheelbarrow-like cart with a contraption mounted on its front wheel that dropped a stone into a bucket after each revolution.
He also delved heavily into mathematics and physics and is credited with a number of advances in geometry, including the methods by which the volume of spheres and cylinders is calculated. However, he is probably most famous for discovering the law of hydrostatics, which is now commonly known as Archimedean's. principle the principle deals with the buoyancy of submerged objects and the displacement of water if that sounds vaguely familiar It's true that's because it's the formal name for the discovery he apparently made in the bathtub while looking at the corona. Supposedly, Archimedes was more proud of his theoretical work than of his machines, which he considered rather clumsy and inadequate to take advantage of Archimedes' great mind. targeting him, the Roman general sent soldiers after him.
It is reported that when he was located, the 75-year-old man was so immersed in a confusing mathematical problem that he dismissed the soldiers rudely, after which one killed him with the blow of his sword. Unfortunately, many of the Archimedean originals. the texts have been lost forever some of the most notable were last seen in the 14th and 16th centuries on the bright side as palum is now in a very safe but unlikely location the walters art museum in baltimore maryland so i really hope you found that video interesting if you did please hit that thumbs up button below don't forget to subscribe leave me a comment with a suggestion for a future side projects video and see you next time
