Long rod question

moon man · 30 Jan 2009 at 20:18

im sure its something you all wonder about but if i have a metal rod 10 miles long and pull it at say 1 metre/second how long before the other end moves assuming its frictionless and wont stretch, ok its not instant or speed of light so how fast is that motion transfered

instants impossible

and if you pulled it say 1 foot but the other end hasnt moved yet is the length of the rod now 10 miles and 1 foot?

Relevant video I saw a while back which I found interesting

cheers
yep that's very relevant, watched and in my watched later and definitely addresses the instantaneous .sound ,light speed questions , guessing if no bond compression it would be light speed but obviously can only be theoretical ,instantaneous is a no way (sorry neighbour gave me some herbs for watching her cat)
