The Bessler Wheel, mystery solved.

Fletcher is also a member there and the conversation is a bit more technical because many of the members are engineer types and a lot of them have been pursuing PM for a long long time.  You might want to consider joining.

The BW post didn't have details other than saying you made an announcement of a runner.  I had to read your posts to get the details.

Glad to hear you joined.  The link in my last post will take you to the BW post.  You will see there is not much detail there.

Sorry gurangax .. I only have 24 hours then I'm heading off again - things to do that take priority over Tomasz's Cf design on about page 26 or so IIRC - (I'd have to think about how to fake the forces to show it as a 3D design) - there, a counter weight had a sliding pivot [shaft ran thru it] so it could rotate - attached to the counter weight was a pantograph [parallelogram] in the z axis with two further torque masses - as the mech fell from position of highest GPE the two masses moved outwards & via the linkage moved the counterweight along its slot IINM - it can not achieve a position of higher GPE at end of cycle or RKE at bdc than it was given at the start when it was hand positioned.

FWIW, Tomasz never claimed it was OU but you said it needed something else to get 'excess weight' that would make it OU.

ETA: FWIW .. the toy's page shows two sets of pantographs, center page - IMO they show linear force & momentum, & Translational KE mechanically morphed/routed into rotational force [torque], angular momentum & RKE.

well you were asking earlier if wm2d will work with the principle and I told you I dont know how to to it with wm2d and you ask me to design something which resembles it so someone can help me simulate it. I know Tomasz design will not work. My point is I need to know how to do it with wm2d. I probably can modify it to match my design.


thanks. regards
