Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

[Omnibus]

What I am saying Omnibus is that the more complex the polygon the weirder the programme reacts. I have given up on the polygon tool after too many failures.

Well, then, how do you propose this to be modeled.

As far as the failures go, all I've seen so far is due to springs, improper settings of the rigid joints and ignoring air resistance (which models internal friction losses). All these problems are excluded in the last model.

Omnibus, are you saying that you believe this model works? What makes it different from any other ramp model? You could use slots to remove the whole complexity at once and see it has no tendcy to rotate either way.

See, I've expressed this belief many times. The crux of the matter is nothing else but the proper construction which would enable displacement under the action of a force. If a proper construction is found that displacement can go on as long as the force is there (and it's always there because it's gravity). Construction is crucial.

As for the slots, you have to show what you mean by that. Could you redraw it with slots?

Oh, and another thing, if you notice the system center of mass is slightly to the right of rotor's axis of rotation.

Here is the proof. What I am saying is correct.

I have mounted the weights on a straight wheel in the correct positions relative to the axle.

If you click run it will turn to the right initially and wobble until it finds its balance as expected.

OK, cleaned it up a little, resetting speeds and just two balls so you can see.

Goes CCW, slows down, goes CW, slows down. Then the top ball starts spinning on its own.

Hans is right... However, if you made each arm into a single polygon you may get more accurate results.

I do not know why but as I mentioned way back the shape of the curve of the holders is inverted and should be curved towards the outside of the rim, not the other way around.

Omnibus, what were you seeing that prompted you that this may be it?

What were you seeing?

...and elasticity appearantly.

No wonder they stopped developing wm2d?
