How to get the WM2D:

Guys,

In WM2D you can set the properties manually rather than choose the preset "steel", "wood", etc.  If you set the Static Friction and Dynamic Friction to zero, you eliminate friction from the equation (for testing purposes).  You can also set the Elastic property to zero if you want it to not bounce off of other objects like a ball of clay, or up to 1 if you want it to bounce off of other object with the same but opposite velocity.  Also, set the mass to whatever you want since your objects could be of any material density as well as extend into the page as far as you want.

Eliminating friction is a good test method.  If you cannot get a working system without friction, obviously it will not work in the real world either.

Well,
here is the video:

I guess I must install the newer version now and play
with the ramp materials to get less friction.
It was a real difference between using wood or
steel for the ramp.
In the above movie the balls are steel
and the ramp is wood.

When the ramp is steel too, the steel balls just
jump back and forth on the ramp, so not so good...

Tnx that meterial thing is a good tip, i keep forgetting that! 

Stupid, because i think eventually result could be in the finetuning as Muchs as in the basic design.. But I'm to chaotic to do that systematically.

Well,
here is the video:

Stefan, please hear me out.

With just the 4 arms in your video, no guides, if it spins fast enough, the balls will be stuck to the outer end due to centrifugal force, right.

Now add a trapdoor at the end of each arm, so if the trap door springs open, the ball will go flying out in the appropriate direction.

Now add an external curved ramp mechanism below the wheel, so that if the trapdoor opens above it, it will catch the ball and allow the ball's momenum to carry it back to the top.

You also need a trigger to unlatch the trapdoor near 6:00 so the ball will fly out at the correct time.

The trapdoor should stay open until that arm reaches the top, and should only close when a ball reenters the wheel at the top, then it should latch until it reaches bottom again.

The wheel will need to be spun up with all balls onboard until it reaches a speed where a ball escaping through the bottom of the wheel will have enough momentum to go up and around the ramp and reenter the wheel at the top. When the required speed is reached, the trapdoor latching/unlatching mechanism can be engaged.

The ramp length and wheel speed need to be synchronised so the ball reenters the same arm at the top it departed from at the bottom.

What you end up with, once it gets up to the required RPM, is a wheel with balls on one side and no balls on the other.

I'd be very interested in seeing a WM2D video of what I just described. If you don't understand what I said, just ask questions.

Thanx,
