Simplest Design...

[raj]

Thank you so much, my dear ME.
Your simulation geometry is not correct.

The right geometry of the design is:
ONLY ONE heavy DISC/wheel/weight/ with eight strings connecting its eight points at 45 degrees intervals on its rim to eight swinging/pivoting points again at 45 degrees intervals on the main wheel, starting from the 12 o'clock positions on both DISC and Main Wheel, connecting around the rims respectively, in orderly fashion.

The connection geometry is quite CLEAR from my Drawings.

yes... it's different, sorry about that.
But it shouldn't matter, because it's about getting the weight where you want it... it doesn't want... at least for me.
I just thought it to be similar.

The approach you are playing with is well known to me. The lesson is where does the weight effect on the wheel. On a single point it reacts to that point but when another point comes into play the weight effect goes strait to the point that the weight is located at as if it was mounted solid to that point of the wheel. Look at my wonky wheel video and see what happens.

It is times like this I wish I had posted all my build videos but most are still work in progress.

I built something very similar to this only the large disc (pendulum) was between two V wheels with the disc in the middle, the ropes of the disc was attached to the two v wheels, it keeled, most of the weight was lower than the axle.

Why the V wheels? The V wheel was for changing the rope length in the hope of pulling the disc outward on the descending side, which worked to some degree.

Why did it fail? It failed because when the ropes was at 11 and 1 they were both taking the weight of the disc, to move from this point one way or the other means the disc has to be lifted, and that needs an outside force or energy input.

My conclusion on your design, I also have to agree with T 79.

Edit, you can forget any help from momentum, when I gave it a good spin it slowed down very quickly, because of the said lifting and the backward pull of the top ropes

raj,

Is it my aging eye sight? No matter how I look at your .jpg drawings, it appears that the string running from twelve o'clock suspending the weight is shorter than the other strings.

My dear Ralph,

Drawings have been done manually.
Here are the dimensions of the drawings:
1. Diameter of Flywheel/Wheel= 8 cm
2. Diameter of Heavy DISC/weight= 2 cm
3. Length of 8 identical strings= 5 cm

The stretched string hanging at 12 o'clock has been drawn accurately 5 cm.
The slack strings could not be measured accurately because of their winding.

I am carrying out some crude physical test.

Maybe if I use swinging weights in pairs, (one or more pairs)...

I really like your design and thought pattern. Have you thought of this?

[david jenkins]

As the rope tightens it pulls the ring/weight to the left and should keep the wheel "feeling" the weights on the downward side.
I reserve the right to be wrong. :)

I like where this is going.
