2 weights on 2 rods of 1 legnth, and 1 rod of 2X length
connecting the weights to each other
make a very unstable COG shifter if the rod attachment points
are right (tested with Physics software) part of B-wheel?
Hot? cold? anyone?
2 stationary weights give 180 degrees turn from a start,
this system, all swinging and chaotic, can give 270 degrees
pretty easy, with fiddling, I got a few revolutions out of it!!
(admittedly, with no friction...)
Perhaps chaos plays a role? Like the Finsrud sculpture?
Where can I see this 'easier to lift when spinning' vid?
