User talk:Bernard Mullers/sandbox/Egyptian pyramid construction techniques

Dear sir/madam, What are the key points to delete this supplement in the chapter 'Levering'? The article that is referred to is published in the magazine ENiM-Egypt 2022.

The method tested by Bernard Mullers [38] is based on levering as well, but it differs in mechanical terms, obviating sudden breakage caused by bending forces. Additionally, it describes the entire building process as well and this theory is compatible with Herodotus's description. Tilt Leverage Cages (TLCs) were constructed by connecting four ship masts atop each other and securing them to a loading floor at the base. Using ropes at the summit, the loaded floor could be easily tilted. The lifted site was propped up by stacking posts at right angles, called box cribbing. Numerous transport stairs with 'larger steps' suitable for accommodating these TLCs on two side-by-side struts, were situated on all sides of the pyramid. At a comfortable height of just over 2 metres the TLCs were pulled using rolling posts to the subsequent larger step. From there, the TLCs either moved towards the unloading site or the next lift was initiated upwards the pyramid. Flinders Petrie's chart, illustrating the stone layer heights of the Pyramid of Khufu, presents evidence suggesting the presence of former transport stairs from the base to the summit. These stairs likely featured steps with a secure and manageable height difference suitable for tilt lifting on struts, estimated from 2 to about 2 1/2 meters (equivalent to 4 to 5 royal cubits). Simultaneously with the top-down construction of the final top layer, these larger steps were closed with stones, restoring the pyramid steps.
