What you think of this simulation

Hi gurangax,
can you please post the WM2D file from
your video please too ?

I don´t still understand, what would be the advantage
of a chain versus a string attachment ?

This is what I am trying to achieve. see the video here

but, in the video it uses string. what I want is to use a chain like system as I've drawn in the previous sketch. Do you see the advantage of using chain now?

I didn't see any advantage in that simulation. Do you have another that may clarify what you are trying to achieve.

The chain is used to modify the position of weights so that the weight on the right will be closer to the center of wheel, weight on left will be farther from center of wheel. I made the simulation long time ago on May 2008. The position of elements is not accurate. Also the wheel doesn't turn as in the video if I don't put torque, that is why I am telling now to use a chain like system instead of string in wm2d. I've tried it before but seems to be buggy. the chain jerks and the string attached to it becomes elongated.

I looked at your youtube video and I have to say it would work better going the other way. But all and all it looks like a non runner to my eyes. You have no overbalance for the descending side weight is trying to lift 2 weights on the ascending side.

I've uploaded another video from my wm2d. In this video it clearly shows the descending side is lifting the ascending side. Actually both weights at the bottom play role in lifting the weight at the top. here is the link

You must also note that this is a string configuration and not a chain like configuration as I wanted. A chain like configuration will modify the weight position so that the weight at the right is closer to the center of wheel, and the weight at the right is farther.
