Hmm - not so .. the green rod is deactivated once the pends pass 6 o'cl and they are free to swing together as one pendulum etc on the ascending side n.b. the rods are there as a proxy lock and one-way bearing combo - they lock again when going over tdc ( 12 o'cl x-axis ) ..Spark wrote:Hmm you need to have the double pendulums free to rotate on the ascending side, you have a lever on them.
I built the lock formula in the 'rod time on' field to lock to the rim when the pends x-position was negative on the x-axis - but didn't bother with this sim adding another condition to act as a one-way bearing on the ascending side when the x-position was positive as the small amount of swinging imo does not hinder the COM positioning for a one-shot sim look-see ..
So when on descending side locked to rim - when on ascending side unlocked and free to rotate CW relative to the wheel ..
** Worth noting imo that when an object hangs freely from a pivot its weight is "felt" for turning moments purposes at the pivot position - when it is locked in any manner its weight is "felt" exactly where the bobs are ( as tho they are pinned in that position * assuming all mass is in the bobs ) - I think this is what perhaps is confusing for some trying to manually calculate or visualize system COM/COG as it rotates ..
