Another Clue!?
I'm nobodies mathemetician,but it seems to me that for Bessler's wheels to attain posted speeds at their respective posted sizes,free falling weights would have been useless,as gravity would not accelerate them faster than the wheel was turning.Those clunks against the side would therefore logically be caused by centrifugal force moving weights around,or by some type of spring aided acceleration.It will help if you hold a weighted piece of string and spin your arm in a circle(roughly 6 ft in diameter,as JB's first wheel)and using a second handed clock,make one revolution per second(as JB's first wheel).In my experience,the weight just flies around without falling.
Trying to turn the spinning in my brain into something useful before moving on to the next life.
re: Another Clue!?
For the Gera wheel, you are right, the centrifgual force is 2.77 times the gravitational force. however, whether this matters or not depends on the mechanism inside. If two weights are connected such that one moving out causes the other to move in, then the centrifugal force can be partially or entirely canceled.

Two weights, one pulling the other in along the same arm wont have the same centrifugal force, it will become less for the one moving inward, so they wont cancel.

If the inter-connection between the two moving weights were non-linear then the centrifical forces could quit easily be canceled. But with a linear inter-connection you are right.Michael wrote:Two weights, one pulling the other in along the same arm wont have the same centrifugal force, it will become less for the one moving inward, so they wont cancel.

re: Another Clue!?
Thats why I was specific and mentioned the same arm. I should have wrote not if, on the same arm.
