Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

[Cherryman]

Well, that was fun...

There are so many variables to set in wm2d that I went nuts. Spheres falling out of constraints. Shit.

Here now what I have been working on.

You are looking at a side view here. The spheres do NOT represent the weights but the extended axles of the dumbbell weights.

The flow can be shown clearly now. please remember the frontal view of the dumbbells I showed you earlier and keep that in mind.

Without motor all kinds of constraint and overlap errors occur, I do NOT know enough about wm2d to fix those to put the model to a real test and look for acceleration(it does!!). I changed so many textures I am a bit lost, but you can see the flow concept and we should take it from there.

Model attached.

EDIT: I FORGOT TO MENTION... YES WHEN YOU LET IT RUN OF A FEW SECONDS (IGNORE THE OVERLAP ERRORS), THEN STOP, THEN SELECT START HERE AND REPLACE THE MOTOR WITH A PIN (IGNORE THE WARNINGS) IT STARTS TO ACCELERATE AND COMPLETELY DESTRUCTS WITH BALLS FLYING EVERY WHERE WITHIN SECONDS. WARNINGS ALL OVER.

If you can make the model more sold, who knows? Also when the weight leaves the lower barrier is should remain motionless and then move right onto the upper barrier. So Yeah I need to slightly adjust the lower barrier (again) Coming off it now moves a little to the left, stops, and accelerates to the right into the upper barrier.

Just ignore the Warning:CoE violation messages 

Please comment and help clean up the model if you can, thanks.

Looks Good!

I like it.. I now see what you mean... and now  i understand the shape of the "creadles"in the outer ends!

Very good work!

I took AquariuZ file, removed the motor, and normalized all the masses (some "balls" and arms were not equal weight).

Great work AquariuZ!

Unfortunately it does not appear to self run.

M.

You need to let it run for a few seconds before you remove the motor and you will see what I mean. It also depends where you remove the motor, bit hard to explain.

I will update the picture above to again show the extended axle dumbbells from the front so it is clear that the spheres are NOT the weights itself, but rather a sideview of one of the axles. (in yellow).

I do not know about you, but this flow concept is good enough for me to start building a prototype which will fit on a desktop. Initial size estimate would be 40cm height, including stands. ALL WOOD except for bearing, weight and axles.

BTW. I confirm that I have no such problems like Mondrasek is experiencing with WM2D.

Tracker, open one of the files that has a motor.  Double click to get the properties box and make sure you have the motor selected in the top pull down menu.  Now change the Type pulldown from Torque to Velocity to Rotation and back.  On mine the value will spontaneously reset to some unknown value.  The file then becomes corrupt and may say zero velocity in this box but stil have a non zero value in use.  The problem does not appear for me if I do not scroll through the motor Types.

Guys,

Here is the file with the motor velocity changed from -1 rad/sec to 0 rad/sec.  Only change.

Now it does not move because the motor is a brake.

Stefan, when I remove/delete the motor I also have the wheel spin backwards.  Not sure what Cherryman was doing with the other torques in the file.

@mondrasek, well then, if we can't have a free turning rotor, unobstructed by a motor which even stopped acts like a brake, then what good is this program? Then, any attempt so far that had seemed negative might not have been negative.

OK, I saw the exchange between @Cherryman and @AquariuZ. Seems the motor can be replaced by a pin but how is that done?

The safest way is to use a pin, and then to drop a weight on it what will fall off.. Then you have a starting speed, with no after influence.
