Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

[mondrasek]

Very good tip.
I always wondered, how I can delete the already calculated frames,
that are always stored into the WM2D file...

Is there no other way to delete the frames easier ?
Many thanks.

Not that I know of.  But I am also new to WM2D.  Played around with it for about a month or so I guess.

Also, custom material just means you are setting material characteristics manally rather than using the few pre-sets like steel or wood.  You manually set the static and dynamic friction, density (mass), elasticity, etc.  This is because there are many more materials than WM2D has in the pre-sets.  Once you find characteristics that give you the desired design functionality, you then select real world materials similar to those characteristics.  It could even lead you to choose a material such as glass.

BTW, every wheel in WM2D will spin forever until you turn on air resistance.  The pin joints are frictionless, and this is not the case in the real world.  So you can add air resistance or a resisting torque to simulate real air resistance and axle friction.  Of course, if any wheel accelerates in WM2D due only to geometry and the simulated gravity, it should be a runner.

Stefan, the initial torque is set to zero in this simulation here: http://www.youtube.com/watch?v=1KlLMA5oFxg&feature=channel_page

in the above KAD9 file there was still a motor set at 1 rad/sec
so it was the drive of the wheel.

Also the background disc was very heavy with over 1000 Kg,
so this is not realistic.

I am trying to change this all now and see, if it will really run without any
motor at all...

@mondrasek,

Of course, if any wheel accelerates in WM2D due only to geometry and the simulated gravity, it should be a runner.

This appears to be the case with @Cherryman's design. So far this is the only working simulation of a gravity motor (or any OU motor for that matter) that I've ever seen. Of course, we have to study this thoroughly to ensure that it isn't a novice's success (by novice I mean myself because I started using MW2D for the first time only several hours ago). I really hope it's the real thing, as it appears to be at this point. Once it's established crafting it won't be a problem, I think, when we have such skilled folks as @CLaNZeR and @X00013. The photograph of Mylow's device which Sterling posted shows a very beautifully crafted device as well and maybe that talented person would be interested in making this device too.

Hmm,
how did you design the polygon 5 of KAD9  ?

If I delete the motor in the center the disc begins to turn
counterclockwise...

Hmm, very strange...

Also the left barrier can not be set as a different colored fill
mode. It stays always transparent...
How did you design these polygons ?
in a different program ?

The disc is only 0.5kg and the steel balls are 0.1kg in the simulation. Where did you see the 1rad s^-1 motor?

I meant the simulation I modified, not the original KAD9.
