Real life experiments that reveal the ancient art and techniques of building Egyptian pyramids. Copyright . However we don't need to invoke those Science- fiction sounding hypotheses when engineering insight can help de- mystify the ancient world. There are also dozens of serious scientific explanations but a close examination of all the practicalities and logistics involved in those explanations indicate that in practice the building project could never be completed that way within the historical timeframe. In our minds and dreams we can build pyramids the size of the Great Pyramid of Giza using only human power and a few primitive tools with amazing speed and success. But in the real world these amazing systems and inventions flounder at some practical obstacle or bottleneck along the way. Much more can be learned by real life experimentation and actual physical trials than by pure speculation. This article focuses on the Great Pyramid of Giza since that construction represents the greatest wonder and challenge. We need to explain the transportation and lifting of not only 1 and 2 tons stones but 2. Actual experiments using scale models.

Some of these tricks have been rediscovered through experience - practical trials and errors with scale models and this is why they are only now being published at this late stage of the debate. A realistic imagination, simple mathematical predictions and experimental modelling go a long way to understand the practical use of acoustics, mud canals, levers and counter- weight techniques for moving large stones. Experiments also suggest that rather than insisting on a single method or technique to move, lift and position stones, different techniques and combinations of techniques work best for different sections and stages of the project. Some techniques may only have been discovered by later dynasties. ![]() Plotter Paper for Wide Format Inkjet. 20lb Inkjet CAD Bond 36 x 150 Foot Roll - 4 Roll Carton - FREE SHIPPING.

They could do that using a large 5. By swinging the ram back and forth like a pendulum slowly building up momentum until the ram impacts on one end of the stone, sufficient acoustic and mechanical energy is produced to shift the stone along the top of other stones without rollers. Some authors mention the way layers of gypsum were spread on completed courses for sliding the stones more easily and cementing them into position. Mathematical predictions and the 1: 1.

Shadoof lifting devices with counter- weights. For lifting stones relatively short distances up onto the lower courses of a pyramid, a variant of the shadoof lifting device with a counter- weight works very efficiently, provided the stones weigh no more than about 3 tons. The best way of setting up the shadoof would be to excavate round holes or sockets in the ground for securing tall tree trunks as the upright poles. In fact rows of sockets have been found in the ground around the perimeter of a few pyramids. Some authors have suggested that these sockets were used for surveying or for securing tent poles. But their size, location and spacing around the perimeter seem perfectly suited to securing the poles for shadoof lifting devices. A 3. 0 meter cross- beam tied to a fulcrum would be hauled up by ropes running over the top of the poles. Perched at the top of the poles, the beam would provide lift to a height of at least 1. To facilitate the lifting operation, two counter- weights . During the lifting procedure weights are removed or attached at either end in a sequence that ensures that at any time the difference in weights at opposite ends of the beam is always at most only half the weight to be lifted. That provides for good control over the operation with minimum manpower and avoids over- crowding the working area. A four- rope noose arrangement will grip the stone to be lifted around the sides in a self- tightening knot for hoisting up by the other end of the beam. One counter- weight always remains permanently dangling; the other is attached only during the lift. Before each stone is untied after setting it down on the platform above, another counter- weight at the ground level is secured . Then a new stone waiting to be lifted can take its place. Using counter- weights in this way the shadoof could be easily operated by a team of no more than 1. A horizontal reach of nearly 2. With 5. 0 or more shadoof devices operating simultaneously, the stones could be delivered onto the platform at a rate of at least 2. The shadoof would not be strong enough to lift the large 1. Nevertheless just over 1. Counter- weight and counter- ramps for hoisting large stones. For moving longer distances along horizontal or near horizontal surfaces, large stones would need to be pulled on wooden sledges or rollers by teams of men or oxen as many others have pointed out. On horizontal surfaces, multiple parallel tracks overlaid with wooden planks and rollers would be the most efficient and practical. Spaces in between the wooden tracks would need to be provided for the labourers or teams of oxen to tread. It was also discovered through scale model experimentation that to start the block rolling, a single knock with a correctly sized battering ram was required to provide additional acoustic energy. This suggests that in the real world the use of levers and/or battering rams of different sizes would have played an important facilitating role in moving and hauling large stones around. A shadoof will lift the smaller stones up to about 1. Other techniques are needed to take them beyond that height. For hauling up slopes, simple mathematical predictions and experiments with scale models . Building several sets of gently sloping ramps built on the ledges that form the faces of the pyramid . The problem arises with much larger stones. The casing stones of the great pyramid are estimated to be around 1. These are more difficult to haul given the limited space on the edges of the pyramid for large teams of men and virtually impossible to haul around corners. However with massive stones the task becomes easier using a counter- weight and counter- ramp principle. This principle multiplies the force of the men walking and pulling the ropes down a steep ramp . Depending on the ratio of the slope of the upward ramp in comparison to the downward sloping ramp the anti- gravitational force on the stone will in effect be multiplied by 1. A stepped wooden structure or clay plastered over stone rubble and edged with wooden batons on other faces of the pyramid would provide the stairways needed for the men pulling the ropes to tread the shortest route down the side of the pyramid. All that we additionally require is a smooth round polished wood or metal pole mounted at the edge of the pyramid for the ropes to turn over. A refinement of this arrangement would be to grease the wooden or metal pole and then wrap it in a scroll of leather or beaten copper. The grease would allow the leather and rope to turn more freely over the pole like a roller and reduce friction of the rope on the pole without making the rope slippery. A large labour force of men would be able to walk . The journey of the stones would admittedly be slow compared with modern cranes but fast enough with sufficient hauling teams to complete the work in 2. Trials to test the effects of friction. A 1: 1. 00. 0 scale model was built to test the effects of friction on a roller ramp system with a 1: 2. Strings of 7. 0 gram lead sinkers were used to represent the weights of average men on the scale of the model. First, smooth urethane coated wooden board was used to construct the ramp, smooth round pencils for rollers and a highly polished steel pen was used as the turning point for the cotton thread . ![]() A 2. 40. 0 gram concrete block was hauled up the ramp by 2. This would be equivalent . Or about 1. 2 men for 1. Next a more realist ramp was constructed with sawn Balsa wood planks, the rollers from dried twigs simply cut into lengths without trimming and the same steel turning point was used. The rougher material required 3. This shows that the force required to overcome the effects of friction and inertia is much larger than to overcome the effects of gravity . Almost the same weight was required . When the wooden track and sledge were saturated with vegetable oil or oil and water this reduced to just over 1. When sand was blown over the track movement was surprisingly improved by eliminating the jumps and starts and only 7. When the wooden track was wet and covered with a 5mm deep layer of slippery wet clay this reduced to just over 9. A little sand mixed with the clay did not have any detrimental effect. A thicker layer of clay . For that technique to work in real life canals would be required to contain the large volumes of clay and retain the water content of the clay. The next step in the experiment was testing a much larger scale model to see what the scaling factor would be. In other words to check if certain unexpected physical effects that are not operating with very small scale models could change the way large scale operations work in real life or vice versa. To check for this the experiment was scaled up by a factor of 5. Instead of 7. 0 gram weights and a 2. Kg girl and a 4. 0 Kg concrete slab was used. The girl was easily able to haul the slab across a horizontal wooden board. The slab was mounted on a flat piece of wood and hauled with a thick cotton rope. Revware – Reshape your world. The Micro.
