Weightless Weight

[ruggero]

The rendering engine of WM2D is atrocious and only supports simple models. More complex models are rendered in such a fashion as to make it almost impossible to see what is going on.

Well well well....I don't say you are wrong, but the wm2d company website tell otherwise.

A lot of very complicated and heavy designs find its way to YouTube in other formats than AVI - some of them are even available in this forum.
How they achieve this I don't know.

I wish I could see a good way of doing this but at the moment I can"t. Any useful suggestions are welcome.

Hello Hans,

You can convert the .AVI to animated GIF and you can also reduce it's size.
This cut's down filesize dramatically by reducing the color palette to less colors without making the picture too bad when it does not involve millions of colors to start with.

hello  Ruggero....

I see a couple of things problematic with your last drawing...I'll only point out the big one

If these are the 'big' concerns...I think it'll have a good chance working

But to meet your arguments:

First of all this is a drawing of the principle.
Second, the topmost point on the drawing is really not at 12:00 but a little to the left of the center-line: This makes the angle to the buttom exchange point less than 90 degree.
Third, put a small weight on the left lever arm (at 11:59) and it will start moving down...as any overbalanced leverarms.

I have made a small build(se drawing below) of a circle with a string/rope mounted on the weight (A) at 12:00 (exactly noon) - the string going down to and turn 180 around the axle, goes up to and around a pulley and then drops to a hanging weight (B).
The weight (B) is half the weight of weight (A).

Okay â€" let go and let the weight (A) fall.
You will notice that the wheel turns over 360 dgr...and offcourse keeps running another 210-225 dgr.

Now â€" the funny part of this lever 'trick' is the way that the small weight (B) seems to gain some of the momentum from the big weight's (A) falling...like, for a short moment eliminating or releasing the tension between the two weights.

It must be like that, because...if you make a start set up with the big weight (A) at 06:00, there is no way the wheel could possible start moving.

What I see, is an acceleration of the big weight (A) that is actually faster than the (beginning) free fall of the small weight (B): It's like dropping the small weight without a string mounted to it.
