This is a scenario if stones were only being pulled up the Pyramid face. As if, they were already accumulated for the day's needs.
The Pyramid build took place 4,500 years ago. I am not sure, why I need to "produce" evidence? I am only speculating, ie. form a theory or conjecture about a subject without firm evidence. The best I can do is point to circumstantial evidence, deduced from logic, which can and have been replicated, in mathematical terms.
The primary deduction is the Causeway(s) angle in relationship to the Pyramids angles, and how each influences the other, in the ability to lift weight (stones) under a controlled condition. This is the fundamental premise.
Khafre's Causeway is approx. at a 5 degree angle. His Pyramid is estimated to be 51.5 degrees. In building a Pyramid using the Causeway as a Water Funicular system, you would want to be in control at all times.
Question? Can the Causeway (5 degree angle) containing a polished stone surface, pull the equivalent of two stones (2267kg / 5,000lbs) up the face of a 51.5 degree angle? The simple answer is YES. The largest denominator is the Friction (COF). The other is a Barge, which can be filled with water, and reach a (State of Equilibrium). Once that is obtained, it can be controlled by a handful of men. There are primarily, two types of friction. Static and Dynamic. Static is the force which needs to be overcome, causing the vessel at rest, to become Dynamic. Dynamic being in movement.
This short movie, represents the condition above. Please notice the operation starts and stops at a COF of 0.05, and 0.06. As long as a (COF) of 0.05 can be reached, you are pulling two average size stones up the face of the Pyramid. A vessel/barge filled with water weighing 60996kg., will pull a counterweight of 2267kg up a 51.3 degree angle.
Here is a short movie, which shows the two angles, and their relationship to each other. It is a Double Inclined Plane calculator in operation. The website can be reached at: geogebra.org/m/ZeZjAfta
The website also provides the Tension, ropes would need to handle. You will need to convert from Newtons.
You will notice, that a vessel/barge filled with water weighing 60996kg. will pull a counterweight of 2267kg up a 51.3 degree, with a (COF) of 0.05.
So, it is possible if these conditions are met. The polished stone would need to be lubricated, and once the men stopped pulling and/or pushing on the water vessel, it will come to rest. At this point, the sled of stones have reached the top, and are removed. Once the other lift (now at the bottom) is ready, they switch the attachment rope to that other side, and the operation starts over again.
At a height of 50 meters, 164 feet, the Pyramid is 82% finished. As the Causeway reaching the harbor water is approx. 1,700 feet, they would stop and start 10 times. This would place 20 stones atop, in one complete travel down the Causeway. To reach the proverbial 1 stone every 3 minutes. The average man's walking speed, is 3.1 miles per hour. I estimate it would only take 6.25 minutes to reach the bottom, and have time to pull the stones off, once they reached the top each time. My illustration will be to size, with measurements for fact checking.
Now did this happen? I have no idea and/or evidence it did. My intent is to show you the POSSIBILITY. Now in kind, please someone show me the same using ramps. Once you attempt that, you will be able to reach an educated opinion, as to the likelihood, of one system over another.
Jacob, I apologize for this long delay, as I did not catch your post. Please be patient, as I am learning Animation using Blender. I have reached a point, where I can animated my AE men in scenes. The quality is surprising, and once finished, I will provide a Youtube link. I will continue to try and answer questions. There are long moments in Blender animation, when Rendering a scene, which allows me to check the board.
