The Documented Ancient Construction Method of The Great Pyramid

Four ancient "Petrie rockers" surround a Pyramid block and demonstrate RACK & PINION mechanical technology - circa 2600 BC with the ancient Egyptian four-lobe pinion-pulley. The four sides of square based Giza Pyramids consist of Stone Racks of steps (comparison - four racks of gear teeth) - wooden pinion-pulley lobes (comparison with gear teethed cogs) engage and step-walk the stone racks when hoisted. All four sides of these Pyramids would be used with as many pulleys in use as required, all working independently and simultaneously, easily building Khufu's Great Pyramid within the documented twenty years of construction. The ancient pulley has a Mechanical Advantage of 2.8 (MA=2.8)
