Hi PICsters!! I had a curious thought the other day, but since the local grocery shop doesn't have the required apparatus for my experiment, i thought i'll post it on the list. here's what you'll need: -an incredibly long and rigid rod. (all you sickos stop giggling, this is a serious sience experiment) -a friend in a distant galaxy imagine the rod to be a few light years long, and very rigid, and it has a pivot point somewhere in the middle. if you push down on one end, wouldn't the other end move immediatly??? what actually travels along the rod to move the other end?? does anything travel at all? please post your thoughts ryan -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
