Scotland revisited

Re: Scotland revisited
I'm reminder of the way a planimeter works. It seems amazing that when the wheel is being dragged over the map, virtually but not quite at right angles. the wheel rotates quite happily.
So, yes, I think rotation of the main wheel is possible from a side to side motion of a one way pendulum. Bessler found he needed 5 to give a reasonable result.

Chasing Equilibrium
With the video we seen two cars ending at the same speed, but with one arriving first.
In our search we are looking for at least 2 components moving towards their equilibrium points but arriving there at different times. Of cause that difference needs to increase overall motion without reducing the arrival time.

Re: Scotland revisited
A proof of MoI equations, interesting.
Re: Scotland revisited
It's more than merely interesting, ecci.
It's a boundary case and the key to understanding the Wheel.
Interestingly enough, a sphere rolling upon a surface has come up before in the apparent generation of energy from the gravitational field. I wonder if anyone remembers where?
I'll give you a clue - "Bruce". :-)

Re: Scotland revisited
The Rattleback is another instance of the significance of point contact boundary condition.

And he took his staff, which he had always in his hands: and
chose him five smooth stones out of the brook, and put them into the
shepherd's scrip, which he had with him, and he took a sling in his
hand, and went forth against the Philistine.

Oops! I've just pressed the wrong button and reported the post as "containing illegal software".
Sorry about that admin. I meant to press the edit button which I now have. :-)
The most important clue that B gives is that he can get the wheel rotating with a single weight, albeit weakly.

Re: Scotland revisited
Correction
A member (off forum) has corrected me and pointed out:
I was wrong. I misremembered. :-(Bessler states very clearly that the weight act in pairs i.e. there are two of them and they are somehow linked.
Sorry if I misled anyone.

Re: Scotland revisited
No, he said that he was mistakenly attributed for the belief that weights acted in pairs. He never actually says if this specifically is correct or not.
He does say it rotates just with a single crossbar. A single crossbar could be anything from a single radial arm with a single weight to a "cross" ie 4 arms, each containing any number of weights.
I do agree though, it makes sense that a single over-unity mechanism, multiplied will produce more output.
I personally think the biggest clue is the way the bi-direction wheel acted compared with the uni-directional wheels, and the speed in which they accelerated.

Re: Scotland revisited
I agree that is an important clue. It reminds me of the Russian Rattleback which can be set to be lefthand or righthand or neutral. One can imagine the the action of twisting wheel to the left flings the turtles clockwise, say, and twisting to the right flings them anticlockwise. I'm sure your technical skills could build a model demonstrating this.
As for the maths, that's well beyond my paygrade I'm afraid. :-(
With a bit of hill climbing experimentation, i.e. altering the variables one small increment at a time to detect any change, implementing that change in the positive direction, and repeat, one could possibly get continuous rotation
The technique reminds me of the way the Messerschmitt Bf 109 wing was designed.
It started off deliberately weak and had increasing stress increments applied to the point of failure, a line of rivets say. That feature was strengthened and another test carried out till something else failed. This process continued till the required performance was achieved.
Teutonic thoroughness in action, eh!
