Zeroing in on Bessler's wheel

[JUBAT]

Keeping in mind that I'm fatalistic and still don't believe anyone is going to be able to solve this, I still say this.

Robervals allow 2 identical weights to be placed at different distances from the center and still maintain balance. At the snap of a finger, if the roberval could be shut off while these weights are at different distances from the center with the one farthest away from the center up top or to the side, then the wheel would self right. Once the weight hit the bottom, then if the roberval were turned on, momentum would easily carry the weights like flywheels into the overbalanced position, and then the roberval turned back on.

It's probably doable in the fanciful fantasy world of sims where you can make anything happen on a computer.

Self-righting is the name of the game I believe because you get the biggest amount of rotation out of it for the effort involved.

Jubat, RB only allows movement horizontally. As soon as there is unbalanced rotation, Potential energy is lost, ie weights fall in a way that their COM moves downwards. The wheel is unbalanced and the only way to balance it again is to lift at least one weight.

The way a RB works with two balanced wieghts, you can move weights horizontally, but they move the same distance as each other vertically. This is why it is comparable with a simple 1:1 lever. With unbalanced rotation, occurs, the further weight falls more.

See the problem? This is not one RB can solve.

If you remove the bottom pin of the RB, the imbalance will instantly happen... ;-)

Okay nice...so what if the bottom pin of the roberval is actually a hammer toy mechanism that shifts from one side to the other? Or if the pin is released, we have it tethered with a cord so it can't get too far away? Maybe all the way one way it's in roberval mode and shifted the other way it's in scale mode.

I'm throwing out ideas with absolutely no logic behind it...I'm so burned out ashes fall out of my ears.

It is a good method to use. For throwing ideas creates a chance for free association of thoughts. These are normally related to the right-brain activity.

Such free association in normally suppressed with our left-brain strict rule enforcement and categorising mind.

But still there is that whisper trying to be heard 'There is something here you are not seeing'.

P.S. Give your left-brain a holiday and let your right-brain some time to live free.

Regards - meditate on this well.

Once again,
For a gravity wheel to work the weights need to move in on the up side and out on the down side. That is to say, the weights on the up side of the wheel, have to move in closer to the center of the wheel and, move farther out from the center of the wheel or axel, on the down side. This is necessary for the gravity wheel to turn.

Again; the weights have to shift in on the up side and out on the down side. I have found the best way to do that is with a toggle linkage, for three important reasons. It is a very simple, it reverses the direction of movement of the weights and when the weight is fully extended out ward, the mechanical advantage of the toggle linkage approaches infinity.

This helps to draw the weight(s) back into the center; not only against the force of gravity, but also against centrifugal force or angular acceleration. The best way to work the toggle linkage is by connecting it to a heavy roller or disc inside of a drum. This provides a smooth continuous movement to the weights.

I know it's very difficult to understand----------------------------Sam

Then again, right-brain firing, up and down could be something other than vertical ?!

So a combination of CF, Gravity & spring stress could create a vector for up and down which is pointing in a different direction.

I have to admit agor, your insults are by far the most hate full----------Sam

[johannesbender]

Speaking in general, i am of the opinion and has always been , that as long as everything to be done is within the energy budget or even free of charge and perhaps with a little to spare, i don't care what exact mechanical method finally achieves it and gets us there , because all mechanical devices uses energy and have energy losses .

edit: have always been.

I think you are seeing something that is not there.
To summarise down in a wall of death is not down but it's out. Therefore a combination of several vectors.

I see no hate in the concept.

Your language has been really hateful to your mothers ashamed if she knew.
So look into the mirror before projecting hate on others.

[agor95]

Hi johannesbender

A fair point; that is why we need energy gain within the mechanism.

It would seam; nothing good can be said------------------------Sam

A rehash if you will,

As you know by now the rollers / discs do all of the work of lifting and or shifting of the weights. The results are very smooth. I.,E., it is continuously out of balance at 3 and 9 and continuously and perfectly balanced at 12 and 6. The movement is some thing, that you could only dream about. However, one disadvantage of the toggle is; it doesn't move the weight very far.

The natural evolution of things, is to add more stages to the toggle / storks bills, to move the weights farther. Supposedly they were important; if that means any thing. It's not a done deal yet, but that's the direction it is headed in----------Sam

Hey Sam, good to see you're still truckin'.
I'd like to speak to these 2 points.

• However, one disadvantage of the toggle is; it doesn't move the weight very far.

&

• The natural evolution of things, is to add more stages to the toggle / storks bills, to move the weights farther.

because they describe the classic corner all PM seekers get painted into.

• sometimes less is more

Maybe others have more to say.

Hi Waltcy!

No way of knowing for sure; have to try it and see if they will work-----------Sam
