Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

[X00013]

Hi All,
I have tried to model the Bob machine over here:
http://www.overunity.com/index.php?topic=2326.msg171876#msg171876

Still need some help with the model.
There is still a motor attached to get the disc to speed
and the rope pulleys are not yet correct, so the weights are not yet
pulled up correctly.

Maybe someone can fix it.
Many thanks in advance.

Regards, Stefan.

Sorry but your efforts r valient and fruitless with wm2d on this build, wm2d cannot emulate pneumatics, nor there delayed response to CF forces.

@Omni , ur havin too much fun with this, I just had to chime in. If you want to draft try http://www.solidedge.eu.com/isapi/pagegen.dll/pages?page=free_2d

Its a free full working 30 day trial, save as dxf, then import from working model. I've been running all the various models, in 2d and 3d, with better physics engines than wm2d. If I find somthing  I will post it. I have found the wheel wants to run backwards, kinda reminds me off the "ball race", shorter path or greater distance with gravityt? Speed and distance wins every time! Like u said somewhat, the math of my pc is determining the physics, which reminds me, u all need a kick ass graphics card and kick ass processer and tons of memory to get good results in ANY physics program. thank u n good nite

Thanks, buddy. Will have to try it sometime. I have SolidWorks but haven't tried it either. Now I'm struggling with AutoCAD. Not a straightforward thing. Anyway. Hope all is well with you and good night 2 u 2.

Stefan, this device, unfortunately, has elements such as springs as well as collisions which cannot be modeled well with wm2d, as was found out. Wonder how fruitful it would be to pursue modeling it? Seems like the worst kind of example there could possibly be to model w/ wm2d.

@ all, dont put to much merit in ur PC's ability to calculate fictitious forces (IE. CF, ), just a heads up, it's not a "bug" in the program. It's a combination of the PC's inability to calculate school book numbers with what really happens. Game engines rock, wm2d suks, to put it lite--lee!!!!!

For all of you making models with wm2d keep this into account.

Rigid joints have a bug I demostrated long time ago. The thing is to use 2 pin joints instead separated as much as posible one another.

The model is beatifull but I don't trust wm2d for all the experiments I did.

When I have the time I will do an power study in your models.
