Jhula principle - increase speed by applying brakes.

It is certainly the polygon problem.  I replaced the angle bracket with a triangle and it runs the same.

I didn't get positive results with that, xnonix (except when there was no air resistance load).  I designed it that way because I suspected the (polygon) angle bracket was causing the effect. Damn, I wish WM2D would sort their polygons.

I am still not convinced that the design will not work in reality; there is a possibility that a spring could bias the torque to one side.  Worth pursuing, I think.

At least we found another bug in WM2D.

The design with the spring is a bit confusing coz a spring cannot make any work.

Well, I'm not so sure again.  I replaced the bracket with a rectangle and it works.  Dingus drew the counterweight as a polygon too so I'll try replacing that.

Hi all,
if you compare the last designs now with the Milkovic 12 times more output device,

http://www.overunity.com/index.php/topic,1763.0.html

we have exactly the same setup !
a See-Saw where at one lever arm is a pendulum !

So we only  need to find the right relationship from lever arm weight and lever arm
length to pendulum weight and pendulum swing frequency...

that is all. Then it will accelerate.

Hi Pranja,
as you are the expert on WM2D,
please also try this one:
http://www.overunity.com/index.php/topic,1213.0.html

I tried it yeasterday again with the new installed WM2D
and when I change the parameters a bit,
I almost get it to selfaccelerate..

I guess I still must change the spring?s coefficient somehow...

I guess I must change it to kx^3  ??

What is a realworld spring like ?

This model was made for me by Tinhead and I still
must see how WM2D works, so I havetofind out,
how I can change the weights of the disc and the ball weight
and get a right spring and weight relationsship.
