A juggler must perform a trick in which he crosses a narrow bridge juggling 3 balls. He weighs 80 kg and each one of the balls weighs 10 kg. However, the bridge can hold only 100 kg before breaking. The lion tamer said that as long as he kept one ball in the air, the bridge won't collapse. Is he correct?

Nerine Feb 25, 2009	Good one!! Knew the 3rd law, guessed that the lion tamer was wrong but couldn't put it into words... Yay for SCIENCE!!
braingle100 Feb 25, 2009	poor juggler.
megabreath Feb 25, 2009	Poor bridge.
ttt3142 Feb 25, 2009	What's under the bridge, anyways?
megabreath Feb 26, 2009	Well the juggler is now.
tamjp Feb 26, 2009	ditto what Nerine said entertaining visual imagery made a dry scientific teaser fun thanks
tamjp Feb 26, 2009	perhaps the lions are under the bridge
wisteriastorm Feb 28, 2009	I got it without the hint, but i said that when he catches the ball the force would cause him to go over the weight limit.(i'm thinking thought that could be disputed, therefore making yours more accurate =]) great teaser
AndrewWalker Mar 07, 2009	easy but great teaser!
Shadows Mar 09, 2009	I can't believe it took six years for this to be submitted. It's almost a classic! Right now, I'm trying to picture an 80 kg fatso juggling bowling balls. I have to try juggling those sometime . . .

Deedee123 Apr 01, 2009	Who makes a bridge w/ only a 100 kg limit?
Deedee123 Apr 01, 2009	And who weighs 80 Kg?
Paladin Apr 09, 2009	Scientifically found teaser and correct answer. Very fun!
bradon182001 Apr 19, 2009	Interesting teaser. I'll have to take your word for the answer, though. Thanks for posting.
(user deleted) Jun 16, 2009	What about the force from him propelling himself forward on the bridge and moving one arm up to throw up the next ball. If he is moving at all, at no point will the force from his 80 kg be applied to the bridge right?
UptheHill Aug 06, 2009	Nice one, keep them coming!!!
skuxdux Sep 02, 2009	ummm it was kind of boraang
doctapeppaman Aug 28, 2010	The average male weight in the United States is actually over 80kg.
JQPublic Sep 28, 2010	It's hope the juggler either doesn't listen to the lion tamer or loses weight!
lyckzx Dec 07, 2010	I got ur point eventhough it's quite confusing..i suggest you put ur computations on how u come up on ur conclusion..& oh, let me remind u that kg is only a unit for weight & not for force..anyways, it's still a good teaser..keep it up!..
AgKKR20 Mar 04, 2011	Easy one...got that right in the first attempt...but thanks for submitting...
SRB_1807 Oct 14, 2011	good one man ....
marcuslikespie Aug 27, 2012	What if he juggled nearly straight horizontal? I juggle that way sometimes, and I don't think the force to throw would affect the bridge.
