Need help with wm2d on a potential working wheel.

haha! 

even that wouldnt make that concept work

Broli,

The answer you seek is simple, but before I explain I must agree with Loop888, your idea will not work. You have four symmetrical pinned wheels with weights all maintaining the same position. Looks good but in fact the weight is all transfered to the symmetrical axles/pins your small disks are spinning on.  The balance of the main wheel could care less as to what direction the weights are pointing.

Now if you wish to check this out for yourself simply hang a larger weight on the bottom of your weight disks, no gears  or mechanical connections required. Make sure that all four are balanced. As the wheel turns they always remain at the bottom, the weights you believe will provide you with OB will always point to the right.

If you realize this fact but still want help with WM2D, sorry I am not your man. I do not use it nor trust it. And yes I am biased as I am to dumb to learn how to use it. My version of WM2D is "Wood, Metal & 2 Days"

Instead of starting a new thread I'll just continue in this one. Same problem different concept  . Since I believe more in illustrative examples here follow some pics of the concept and a wm2d model.

For the people that have wm2d you'll two equal forces acting on the joint all the time. this is normal. The point is that the force on the joint while at the right side (need to zoom out quite a bit to see this) is substantially bigger than on the left side. Yet the wheel doesn't seem to accept this and just spins back.

I did not fully trust wm2d but atm it's the only method I have of materializing my ideas. Or I overlooked something or wm2d can't break the law of conservation of energy.

what?

Haha indeed "what". I think this is the wheel. I've went through the house to try and build it but I found nothing bu junk. I believe wm2d can't handle this. Here's proof...



The wheel stops there and starts to turn ANTI CLOCKWISE. Yes that's correct. this should be physically wrong. You have a frigging force that's 10 times bigger than the other side. Yet it's turning the wrong way. Not to mention wm2d throws errors every time I run it. I believe this is a truely working wheel. Can people please help me with a build. I will explain everything that is needed.

Edit:

Here's some more madness that show the torque of the wheel going from 12 o'clock till 11 o'clock clockwise.



As you can see the it has a lot of torque on one side and pretty much nothing on the other. YET THE SIMULATION DOESN'T ACKNOWLEDGE THIS.  What's also fascinating are the huge spikes that reach up in the millions as if it wasn't to not disobey the conservation law :p.
