MTs, WM2D, and WM Basic Language Script Code

Georg,

Is this a trick question? I think it could be any even number, except two, two might not be enough.

The weights have to work in pairs, so there has to be even numbers. of weights.

Am I wrong? Sam

[Georg Künstler]

Sam,
it is Not a Trick question.
Two and two is correct, Pairs.
but what is With the clue "Herde".
The connectedness is needed to Make the wheel Run.
you create a different acceleration of the weights in each Segment .
swinging is correct, it is Better then sliding,
the question remains,which Version is it and where is the Start Energy located.
With an higher rpm all the weights will be on the rim,so there will not be an folding anymore, the start effect will disapear.
Try your Luck With this construction you will Learn a Lot.

[Sam Peppiatt]

Thanks George,

You are right, only the experiment is meaningful. Good luck with your rollers,

Sam

[thx4]

George,
will you be ready before June 6th? :)

[Georg Künstler]

Hi thx4,
if you come along before June 6th, then we can make the finish assembly, the pieces are ready and are laying in my barn.
I cannot put it alone on the support, it is to heavy.
So feel free to come along, and we can make the first test run together.

Geometry question. If N is the number of sides of a polygon, can angle D be expressed in terms of N? See attached figure.

Hi Wubbly

Working in degrees I think it will be:

D = 180 - ( 1/2 (180 - (360/N)))

Thank you Mick. I'm sure that will come in handy in these MTs somewhere.

The cylindrical weights with the add on.
Now they can roll or swing in only one direction.
I like to have it in lead so that the mass is more concentrated.
To get it in lead it will be a special model.

To support Ovarons translation of "SCHWUNG", my construction will not swing back and forth, it will stop always on its highest position.

And you see it looks like a pencil and not as a coke can.

I have made experiments with different diameters of the cylinders, the result was always better when the diameter gets smaller.
The translocation position was growing when the diameter was dropping.

Thank you for such an interesting thread. Even more so with the contributions of other members.

I kind of skipped it as it has WM2D software element. Not being any good with commercial software :-)

The naming of parts on 13th May is also a good idea.

Perhaps we need to observe the whip-effect of a scissoring mechanism in MT024?
What could be the function of those "screw threads" he mentions?
One brainstormy thought tells me (I don't know how or why that should actually happen there, but anyway) that when you screw those weights in and out, that it simply dampens those folding speeds immensely.

When looking at a proposed design I look for asymmetry resulting from it's movement.
Therefore the rope 'G' could be flexible or the perceived change in length could be cause by rotational movement down the "screw threads".

When rotational movement is involved I think of the delayed movement and storage of inertia.

Thus preventing the dropping on the right to soon and the collapsing on the left as soon as possible.

Wubbly,

I have a question for you, if you don't mine me asking. How did you happen to pick MT-24? Out of 142 worthless drawings, how did you manage to pick the right one!?

I would love to know the answer, Sam Peppiatt

[Sam Peppiatt]

To@,

I get the feeling that no one has figured it out yet. Here is the key to it, it's very subtle. If you have 4 weights around a wheel, equal radius, and of equal weight, say at 12:00, 3:00, 6:00, and 9:00, the wheel should be perfectly balanced, right?

Now, if you move any one of those weights either direction it will throw the wheel out of balance. Whats better yet, is if you move any two of the weights closer together, (as in MT-24), it will be OOB even more.

This is the secret to Besslers wheel. Instead of trying to lift the weights up and letting them fall, he simply shifted them along or around the circumference, to produce an in balance.

MT24 was chosen because it seemed simple enough to simulate.
I was mistaken.
It was hard to sim.

Many of the MTs, I can't figure out what Bessler is even trying to show. Cross those of the potential sim list.
The ones with bellows or water, well, I don't know how to sim those. Cross those off the list.
Many of them are variants of each other, and the problems in one show up in the variant.
And some are just Whiskey Tango Foxtrot.
The list of simmable MTs gets whittled down fairly quickly.
WM2D has a limited set of constraints that can be applied to bodies. So the question becomes, what set of constraints can I apply to bodies to simulate the MTs?
If Bessler had a simple mechanism, it should probably be able to be simulated in WM2D.

But take one non-working MT and combine it with another non-working MT and somehow magically wind up with a working MT? Seems improbable.

By picking off some of the simpler MTs, something might be learned.
Hopefully that something is not that Bessler was a frog.

But we still engage in that … what's the term … Willful suspension of disbelief.

[Wubbly]

Yes, there it is.

[Sam Peppiatt]

Wubbly,

As luck would have it then; we were due some good luck. I don't know if I would ever have figured it out but, for you--------------------
