A little story about pyramids

 
Egyptian PyramidsAncient Egyptians were some architects particularly since Egypt is today the largest stone monument on Earth, and the only wonder of the ancient world preserved until today, the Pyramid of Cheops. Studies have shown how to build: as the pyramid rose, around, workers made a ramp, which lifted the stone blocks on wooden sleds like. Thus, they put block after block, until the pyramid was completed, then ramp was removed, leaving only pyramid in splendor ei.Vârful pyramid is covered with gold. Today, in Egypt, only a few pyramids are full, unfortunately.Pyramids of Giza were built during the Fourth Dynasty pharaohs and pharaohs Cheops assigned (the great pyramid), Kefren (son of Cheops) and Mikerinos (grandson of Cheops). To compare them is necessary heights of the three pyramids: 148 m (Pyramid of Cheops), 143 m (pyramid of Kefren) and 66 m (Mikerinos's pyramid). The four faces of these pyramids are equal to each other and are oriented towards the four points cardinale.La the time the pyramids were built in Egypt not only to preserve the remains of the pharaohs, but to overwhelm by their greatness, the subject . Pharaohs prestige was high time, given that after extensive expeditions of conquest, they conquered new territories, managed to accumulate new wealth, became owners of large masses of slaves.Great PyramidGreat Pyramid of Giza built by Pharaoh Kheops (Khufu) in the Fourth Dynasty (4500-4700 years ago), and part of the complex on Giseh. The designated by the opening of Kheops pyramid is the son of Harun al Rashid, the caliph al-Arab Mamum, which brought to the foot of the pyramid, then still clad in bright polished boards, a whole army of masons, architects and labor. It is said that between the plates cover the pyramid could be introduced even the tip of a Damascus blade. The aim was to discover treasure Caliph pharaohs, and especially, steel weapons, unbreakable glass and other miracles that are widely believed to be abundant in the dead room.Building the pyramids of difficulty overcome any structure built before. Cheops and the building located at Giseh, on a pedestal of rock, located 40 meters above the ground. The site itself involved numerous infrastructure projects: construction of a canal deviation, a port of an access road to the plateau. It was also necessary, digging underground galleries, mining copper, gold and silver, the development of the maintenance tools. The main problem was it, but transportation. Egyptians resorted in such cases the Nile (at that time ignored roads) and, because the pyramid was far enough from the river, was necessary to build a bypass until near the pyramid.Transportation problem was more difficult as some stone blocks weighing 60 tons, not to mention the fact that they had raised to a height of 130 meters. How did this, nobody knows. You can speculate, can develop theories, but nobody can be sure that he found exactly the method used at that time. For example, for a load of one tonne displacement force on a flat surface must be 150 kgf. A man working 8 hours per day, advancing by 0.60 m / s, could not only develop a driving force of 12 kgf. Ergonomic experience also shows that, on a slope, the energy available to move inversely with the slope decreases, which means a 15 percent energy slope is very small, to become almost zero to 20 percent. Therefore, slopes used for moving blocks of stone had an inclination higher than 9 percent. For such a value is very low energy availability and, reducing speed, it is estimated that 10 people are able to tow a tonne in a given time. Entrance to the royal tomb is carried out through a narrow gallery which opens at the level of the 15th rows (row of brick) and evenly down more than 28 m by early corridor leading to the royal tomb. But descending corridor extends beyond this intersection, keeping the same slope, 77 m, to get under the first rows of the pyramid. There, carved in rock, a small corridor leads to a horizontal underground chamber empty, with a ceiling and a floor plan and polishing with many irregularities.Back to the point of intersection of corridors and take a corridor forty feet upward leading to the great gallery (47 m long and 8.50 m height) is constructed of fine Mokattam limestone, so perfectly cut and polished, that Arab writer Abd al-Latif, reported that between the stones can not bring any action or even a hair. In section, great gallery has a curious, at the bottom, the middle is a passageway which is 1.04 m wide on both sides, two banquets each 0.50 m wide and 0.60 m high, so that the total width of the gallery is 2.04 m at a height of approximately 2.50 m above the banquets, gallery section begins to decline by seven withdrawals succesive.Se reach the famous King's room: five spaces King's Chamber is King is above the chamber, called construction rooms, they have walls made of granite blocks and have a very small height: a man may make in them than going to his knees. Last of the rooms is covered with tiles laid diagonally, which strengthened the assumption that they are designed to take the weight of the enormous mass of stone above, thereby building a flat ceiling in the King room, across the room and waiting room, including floor-were dressed in black granite, king room, built of large granite blocks and polished perfectly placed, was made, the pyramid was built, a beautiful red granite sarcophagus without a lid (not yet discovered), located on the axis north-south.Another room, the hall Queens Chamber horizontal, the point where the great gallery corridor continues upward, the inappropriately named "Queen's Chamber." The king and queen rooms are placed two ventilation channels. These channels range from about 0 , 90 m height from the floor and a section of 0,20 x0, 15 m, widening slightly to the outside. channel leading from the king to the north side room (the pyramid) is 71 m long, and one from the side South is 53.20 m Because these channels, which are in constant touch with the outside, even if the name of Queen room .. ", as that of king room .. the Arabs were given after as the ceiling, the Arab graves , the room where a man was buried has ceiling plan, while the room where a woman is buried up into the ceiling panel. The pyramid is closed, any human activity inside and especially in the two rooms can continue: the two vent channels each room, coming out - one to the south, another to the north - is heated by the sun pyramid faces differently. allow sufficient ventilation.Entering the room where the royal sarcophagus initially unthinkable, was forced by greed robbers, who found means to seize wealth from Kheops regal.De tomb we have left only the memory of a great king, a god on earth, who wanted to leave future generations a monument worthy of his name and his father, Ra.
