Hi at all, in these examples have noticed an interesting and strange WM2D behaviour; unfortunately I am not able to understand if it is an error of the program (glitch) or if it is the exact simulation of that that happens in the reality. Can you also try these two simulations ?. If what is seen is then real there is not doubt: it is a clear "OU" phenomenon and maybe it is really what to which Bessler was mentioning. I would like to know your opinion about this. Could it be a "real world" behaviour ? I insert some screen shot from WM2D and two files in the format for WM2D zipped.
Paul

Nice work Paul.
I can not tell, without some a,b,c, or arrows, but I think Ken can help with this simple wm2d sim you are offering.
It looks like it may be a glitch in the system, or you may not have the program set with air resistance.
However if you are getting it to continue,and all settings are correct,Congratulations.
You will of course check and re-check it, but seems like good idea to me.

Paul...
Whenever I see the word "latch" being mentioned, then I know a design is in serious trouble. Well, if you intend on making latches using WM2D, then all I can say is "good luck". I went that route last year and quickly discovered that WM2D is not really that suitable for such detailed mechanisms.

Yes, I'm sure that there are complicated "formula" type latches that are possible with WM2D. But, although they may work, what assurance does one have that a real latch can be made to work as they do? This is why, when I did give latches a try, I tried to actually make models of them. I quickly learned how unreliable such a system can be for controlling the movement of parts within a model.
In an actual physical model that worked, a latch would have to be able to engage and disengage rapidly and repeatedly for, perhaps, hundreds of thousands of times during a demonstration of a device. I just think it would be too complicated and failure prone to have been used by Bessler. I see his devices as consisting parts that moved due to their continual change of orientation in the Earth's gravity field and which were completely constrained by stops. Thus, no latches would have been required.
I know all to well that, when everything seems to fail, one is tempted to advance to the next level of complication in an attempt to triumph over the problem. I am trying to avoid this temptation and following Bessler's observation that other "mobilist's" designs failed because they made them too complicated.

A mechanical latch might be a problem but if you look at the engineering of a latch you have two requirements:
(1) It opens and closes holding or releasing something.
(2) It has a timing.
That's an elementary electro/mechanical engineering problem.

Seeing as how we can pretty well rule out electro-mechanical use.
I would say that a timed pendulum would make a great activator for a latch release system.
