When I say the question is still unanswered I mean in this thread.
I have a copy of 'The Secret of the Great Pyramid' by Bob Brier and Jean-Pierre Houdin, but have yet to settle down and read it from cover to cover.
From what little I have scanned so far, and if I understand him correctly, Houdin is hypothesising an external ramp up to the level of the start of the Grand Gallery, and then a counterweight system (the Gallery) up to the Great Step.
Hi Robin (MJT),
Houdin is debunked.
He illustrated devices, that are useless in the real world.
1. Counterweight system: He uses men to pull back up the counterweight and reset it for another pull. He demonstrates no "simple machine" which can acquire a mechanical advantage. In doing so, you save or gain no energy. You might as well, have just used the men which pulled up the counterweight, to just pull up the load of stones. Do they both not weigh the same? Or, is the counterweight even more weight, which translates into even more man power needed.
Just how dumb is that?
2. Corner turning device: In one of his movies, it is stated he still had a problem to overcome, "how to turn the blocks around the corners ends of the ramp". So, he constructs a lifting crane device, which is actually an inverted lever, and shows 3 men pulling up the stone to make a 90 degree turn.? Really? They manage to pull the stone up through a dark, smoke filled corridor, though reaching the end, they can't manage to spin the sled 90 degrees, while remaining on the ground? Has anyone ever taken the time, to fact check his proposal(s). If you do so, that lever requires 1,100 lbs. to pull up the 5,000 lb. stone. 3 dangling men cannot do that.
There is weight in the arm of the lever, though how much will it help? These are Douglas Fir Telephone Poles. Estimated weight for the average pole is 489 lbs. and 15% lighter due to dry climate = 416.65lbs. A 20ft. poll, and we are only using 18'. As shown in the lever calculator, 1,111lbs - 416.65 = 695.35 (700lbs.) Well, that almost works. 3 men who are 233+lbs. could dangle on the ropes could do it. One additional problem. Houdin shows one man with a small pole, which is used to support the lever arm in between lifts. How does he lift the lever arm high enough to remove that poll? That pole is supporting 416 lbs. I would like to see how that is done by one man. Getting on the other end of the pole will not help either, as then the lever is working against you... The only solution would be to use a sledge hammer, to try and break out the pole at the end. That works?
Here, I have the solution...
Make the tunnels a cork screw. Then you have no corners... Problem solved. LOL "The Conical Pyramid" Instead of the "Conical Pyramid", maybe I should I call it, the "Comical Pyramid"?
But wait, I have a funny looking map to show you. It's all hidden behind the walls...
