Hi Sirius, you said, "'m still reviewing but is it possible they used different roller systems and lubricants to increase mechanical advantage when resetting the counterweight?"
I'm not 100% sure of this, but IIRC, there is evidence of the AE using animal fat as a lube on wood.
I'll try to verify this later....busy day.....
>lubricants to increase mechanical advantage?
Yes, dropping the cof will help in any situation. Though it is not considered, in and of it's self , to be a simple machine.
Where do you see any mechanical advantage, that could not be employed, by just pulling up the stone on the outside? Is it lost on you, that his resetting of the counterweight, requires more effort, than just pulling up the outside stone. You are also pulling back up his heavy contraption, which provides no mechanical advantage.
Study "simple machines" and their mechanical advantage, then show me where he uses them differently. Roller could be used anywhere. You only have 6 "simple machines", to gain any mechanical advantage. [www.mikids.com]
I see him using 3 of them, ie. Pulley, Wheel & Axle?, and Incline Plain, but all three could be used outside on the lighted stone as well. So, then where is his mechanical advantage? The answer is, there is none, and he is actually increasing his work load, by attempting too decrease it.
Is that so difficult to understand?
