Currently, the American physicist latest research may uncover the secret of the ancient Egyptians built the pyramids, the giant stones four weeks bundled sticks, stones rolling handling will greatly minimize drag.
American physicist latest research shows that the giant stone tied around a stick, will significantly reduce friction, effortlessly handling the giant stones saving.
According to foreign media reports, the ancient Egyptians built the Great Pyramid of Giza magnificent, its history can be traced back to 4500 years ago, but at that time science and technology behind how moving boulders to build the pyramids is still a mystery. Currently, physicists announced when the latest research is how the Egyptians built the pyramids, is likely tied sticks, stones rolling around in the huge run, this can greatly increase transport speed, saving manpower and material resources.
In the experiment, they will stick bundle giant stones four weeks, it has a dodecagonal shaped configuration, handling is easier to move. Pyramids of Giza is constituted by 2.4 million limestone boulders, each weighing 2.5 tons, which indicated that the workers must carry every day about 40 boulders, scientists speculated the ancient Egyptians should hold some relatively easy to handle mobile technology.
Indiana University physicist Joseph – West (Joseph West) pointed out that technology bundled sticks on the building stones, boulders make a right angle into a dodecagon structure. Based on this structure carrying boulders, stones large extent reduce the resistance.
West and colleagues conducted a study to test the model, they are a long 20 cm wide and 20 cm high 40 cm tied 12 sticks and stones at four weeks, the stone weighs 30 kilograms, in experiments on the rolling stones, They found that the dynamic friction coefficient of the normal movement of the stones is only 0.3 friction coefficient. This means porters carrying boulders using this method is very easy, just 0.15 times the required strength rope pulling boulders, if it is 50 workers carrying 2.5 tons of a boulder, you can move 50 cm per second. But the experts are not sure whether the ancient Egyptians using this method, after all the relevant archaeological evidence has been found.
