Thanks for the update, Steve. God I hate the word debunked. I wonder if you are throwing out the entire theory based on one aspect of the visual? At any rate, I was only suggesting Houdin as an example of how a theory for making the GG and functional rather than esthetic feature might work.
It has honestly been so long since I watched that presentation that I have forgotten many of the details. Here is a brief clip of his proposed GG function for anyone else that has forgotten:
Here is a brief article from Archaeology as well:
It seems to me there are some features that suggest Houdin may have been at least partly right but such as the gravimetry print and some features of the exposed corner but I'll defer to your explanation for the other features.
Thanks for the input.
My remarks below are not aimed at you. Just part of the discussion, so hopefully others will understand.
In his video, the Grand Gallery was used with a large counterbalance. This counterbalance and it's ropes are used to pull stones up on an outside ramp.
Below his video, he claim:
"With my partner Dassault Systèmes, we carried lots of simulation regarding the counterweight system sliding in Grand Gallery. The whole mechanism was tested in all the situations and everything proved working fine. A virtual reality 3D animation was then done for a better understanding by the public."
He carried out lots of simulations regarding the counterweight system. The whole mechanism was tested...proved working fine....
OK, let's take look at those claims.
What is the definition a Counterbalance?
a weight balancing another weight; an equal weight, power, or influence acting in opposition; counterpoise.
verb (used with or without object), counterbalanced,counterbalancing.
to act against or oppose with an equal weight, force, or influence;offset.
First, Google counterbalance, show yourself all the machines which takes advantage of a counterbalance. In the case of a forklift, it is counterbalanced in the back, with a rated weight, so it won't tip over. It's hydraulics that performs the lifting.
A counter balance is, as it says, simply in balance from an opposing force or weight of equal. So, how does that translate into any additional mechanical advantage? The fact that you attempt to use it, as some form of a mechanical advantage, is non existent. Once it is out of balance, by definition, it is no longer a counterbalance. When using it in relationship to ramps, (incline plains), it's the Incline Plain that is a "simple machine" , and gives you a mechanical advantage, and not the counterbalance.
You have two opposing weights. So, any effort to pull on one side, is a opposed by the weight on the other side, regardless of it's force or mass. That's the "counter" portion in the term counter - balance. It's countered.
Here is another way of looking at it. What happens if you remove the weight from one side? Does it conveniently float in space, while you attempt to replace ropes or weight on the opposite side? No, it immediately pulls or drops. Does this happen with all degrees of weight? As in, 1 ton vs 80 tons? The answer is yes. So then, how can Houdin derive any mechanical advantage in using it to pull stones up a ramp? Instead of a scale (counterbalance) with two equal platforms, you can use ropes to "offset" the "distance apart" of two opposing weights. That's all you can do, change the distance. Now then, if you can hold down those ropes and/or lockup the stone inside (60 - 80 tons of pulling force) you could attach a stone outside on a ramp of equal or less weight. If the ramps and weight were equal, you go nowhere, because you are in balance. If the ramp on the outside is less of an angle, you now begin to gain a mechanical advantage, as well as, loss height and/or increase the ramps length. So then, a counterbalance offers you NO mechanical advantage. it's the Incline (ramp) Plain, that does.
Houdin inside the Grand Gallery, has a weight which is larger than the stone he intends to pull up on an outside ramp, into a higher position. To reset that weight, requires all those men in his video, to pull back up the heavier weight found inside the Grand Gallery. Well, if that's the case, go pull up the lighter stone and forget about the big stone inside, as it affords you no extra advantage. Additionally, GG is only 140 feet long, and the stone he uses looks to be like the ones used above the Kings chamber, 40 ft. long. So the longest pull could only be 100 feet. That means, his other ramp can only be 100 feet, unless you plan on doing a double pull/reset.. A double pull just adds to the dilemma.
"Lot's of simulations, working fine, whole mechanism tested"...
Why would anyone pull up a heavier stone, just so they could eventually, pull up a lighter stone?
