Play it simple or double...

.....or half turn (180 *) , or full turn ( 360* ) of a continuous ( "free" ) gravity accelerated unbalance due to a simple variable leverage , as :

.....or as :

So , the possible "conundrum" of our forum is minimized .....to "remake" the gravity unbalance ( torque difference ) , on the same side of the fulcrum two times ( 0* and 180* ) or once again ( 0*/360*) only...but double.
