Thanks for the response. Why does the counterweight have to be a static 60,000lb, as you stated?
My point was that the film states there is a counterweight system to the counterweight as well that consisted of up to 15 stone weights that ran down the ascending passageway. This would allow an advantage to the reset process.
Why would you need a 60,000lb weight to lift 60,000lb when you have both the counterweight and the 180 workers working together to raise the granite blocks?(which is what I assume you are referring to) Also it looks like the were using the same system to lift up to 7 smaller limestone blocks at the same time so the system would be able to multi-task between different weights for different jobs.
But the fact remains that the 180 dudes and the counterweight worked together to lift heavier loads rather than one or the other at a time. I agree that it is a pretty complex >system but there is evidence to back it up.
In a counterbalance system, it doesn't matter what weight one end is, as long as the other end is the same. It is countered.
When you release one end, the other end comes crashing down. It in and of itself, does not provide any "additional mechanical advantage". A counterbalance is simply "a weight that balances another weight".
Place a 60.000lb stone in the system, still requires men to pull up that stone, ie. 180 men. Those men could just as well pull up another stone outside the GG, provided the friction was equal or less than inside.
As I said, a dowel which is greased and spins on the two rope ends, and is pulled with a rope which makes a 180 turn in the center with one rope end attached, becomes
a movable pulley 2:1 ration. No counterbalance contraption is going to out perform that "simple machine".
Why on earth, would you use 180 men, when you can use 90 to accomplish the same task?
Watch this: [www.youtube.com]
Once you understand you can gain a mechanical advantage, based on how you use your ropes, you will seek to gain more advantage with other arrangements. Eventually you would derive a, "block and tackle" arrangement, ie. 3:1. = 60 men.
What do you see below? It is a Counterbalance. Each stone is 60,000 lbs. All things being equal, if you place 1 additional lb. on side, it will begin to pull up the other side.
The problem is....the other stone is now at the bottom. What did you accomplish? Nothing!
So if that is the case, ask your self...why was it proposed? It can only be one of two things.
1. They were both really stupid, and don't understand what they are proposing,
