Besslers prime mover and its enabler.

Well i mean other planets are valid options for gravity power experiments too.

Mornin Rox .. take a look at my changes to your original WM sim - put some Outputs and manually entered Inputs into it - just check it over for consistency etc, and is it doing what you intended ?

I changed the grid units to cms and left the masses as grams for the small scale you built - check out the System COM showing in the sim for the lever arrangement you present (anchors on objects make them invisible to the sim) ..

Forgot to add the sim in my haste to get a coffee and stretch the legs ..

I suspect the disconnect between the partial sim and real world build is the need for it to do work.

Hi Fletcher thanks for doing that for me. I'm not sure if any file that you send will run on my version of WM2D and I don't know the file sharing site so can I just ask a few questions? Did the main wheel rotate and did the mechanism rotate? I'm guessing the mechanism did from what you are showing.

Try downloading the file and opening it and see what happens .. otherwise look at the animations and pics i guess ..

Did the main wheel rotate and did the mechanism rotate? I'm guessing the mechanism did from what you are showing.

In this animation of the sim I deleted the anchors and turned OFF View > System COM ..

You can see in the Outputs the y position of the green counter-weight is below horizontal which creates a torque - yes, they both will turn now ..

TBH I'm struggling to see what you are trying to get at here - do the yellow 20 gms and the blue 3 gms "vibrate" as they are rotated, slightly changing their relative positions to each other and the counter-weight ?

Sim attached ..

OK .. I see that the animation stops recording fairly quickly (too much detail) - FYI the disk rotates CW until the green counter-weight (rhs) is almost at the same height it started from but on the lhs - IOW's a pendulum .. then it swings CCW etc etc ..

The lever system rotates CW until it reverses and swings backwards etc etc ..

I will have try in a bit Fletcher to see if it works on mine. Really the idea is simple. If that wheel can rotate 180 Degrees and its still going strong AND the mechanisms can overbalance themselves then it would simply keep on going.
Graham

[Roxaway59]

The wheel turns because it has made an inverted pendulum.
Graham

[Roxaway59]

Hi Fletcher I have just realized what yours is showing. The pendulum is at 3 o'clock in WM2D that is different than the version I did in Algodoo which was more like 12 ish.
Graham

[Roxaway59]

What it really has to do is swing more than 180 Degrees.
Graham

By the way the files you sent do work on mine. How did you stop it from running out of memory. I couldn't get mine to work properly?
Graham

[Roxaway59]

One thing that I don't understand is why the COM is dead on quarter past.
Graham

[Roxaway59]

Here is a screenshot of where the one in Algodoo finishes. Spot the difference lol.

That's great .. Set World>Accuracy from 1000 fps (as you have it) to say 200 or less will reduce load on memory ..

See sim and pics of your lever-pendulum - note I removed the short lever as it was not necessary, and added a red massless rod between the 2 weights as a line of sight for you - you can see that both weights are higher than the mid horizontal line thru the lever itself - this creates a top heavy scenario with the lower pivot position relative to the weights position on the lever ..

Next look at the System COM icon up close - it is slightly to right of vertical about the lever pivot - this gives an automatic CW bias when the sim is run i.e. inverted pendulum .. the priming motor could be removed entirely IINM ..

[Roxaway59]

Hi Fletcher yes the mechanisms themselves need to overbalance but the main pendulum I usually talk about is the wheel itself and Ideally that needs to be near the top of the wheel when the mechanisms are set right on either side of the wheel.
Do you think its possible to move that COM further up?
