It's not just a 'rubber band', either. This is a _bungee cord_. These are a fair bit stronger than the rubber bands you fling at each other in boring lectures. Have you ever tried to stretch a bungee like the ones used for bungee jumping? Bet you have to put your weight into it. Bungee jumpers use a composite cord. Mostly rope, with a length of bungee on the end of it. This keeps the bungee from snapping up too quickly when the jumper is released. > I see no reason why a smoothly increasing and decreasing force (the > bouncing jumper) coming from a direction that is barely changing (varying > over only a few degrees) should be such a great concern. What is keeping the abruptly increasing and decreasing force 'coming from a direction that is barely changing'? The jumper might be bounced all over the sky. > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- > Email to: lonhyn@gulag.nas.nasa.gov Human at: 415-604-3989 > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- +------------ | rob@ireta.cynic.wimsey.bc.ca | Rob Prior, President, Still Animation Logo Design +------------------------------------------------------------ Brought to you by Super Global Mega Corp .com
