+Kratos Aurion Plays The bottom horizontal part is under very little pressure. Most of the pressure is on the right and left side cylinders. The hook pulls on the middle cylinders and those middle cylinders pull on the side cylinders. The bottom part doesn't allow it to be pulled apart, and the top doesn't allow it to collapse inwards. Paper has very good tensile strength, and if heavily layered, can withstand enormous pressures.
I got a bit inspired to for building my bridge.. im not going to take your design but the support is all i needed to see for this and the beam too. XD anyways you did a great job!
More like a paper and glue bridge. Look at the description for the large amount of glue used. The glue probably made up a significant fraction of the weight of the bridge. Looks like a composite material, similar to carbon fiber or fiberglass, but made with paper and glue. The glue and paper together give it its strength. The paper alone or glue alone couldn't hold nearly as much.
Its Plano West, that's a rich high school.and is also one of the top public schools in the nation. I don't go to that school put I drive by it sometimes and dam looking at the houses by the school @.@
thats awesome but will the change in glue make a difference? i go to west and we can only use elmer's glue now. But, instead of paper nails, we can also use toothpicks, but only for holding joints.
It scared me a little when that thing collapse. If the students didn't follow proper safety procedure and just take things bluntly, the weight could have crushed the bones. Proper position guys safety......
@Gregorybot what did u come up with? If I was there I would fold the paper lengthways mountain then valley until the whole sheet looks like a fan and if u suspend it like in the vid it would be pretty strong!
all that brainpower to make paper bridges that hold 1,000+ lbs, but no weights bigger than 25lbs... They knew it would hold 800, why not grab some 45's to make room?
Pulling from a single point like that isn't testing the whole bridge, it's testing the structural integrity of that point only. If the weight would have been 3 inches left, then what?
Best part (that nobody has noticed yet) is that the bridge could have taken more weight if the moron professor didnt nudge the bottom chord with his arm. LOL
I do think the layers were probably glued together and allowed to dry, rather than just rolling up paper. This would allow a papier mache' style arrangement. I've seen pens made of recycled paper that were pretty strong. Almost as strong as a plastic pen or pencil. Now the central member wasn't taking as much force because it had a mechanical advantage in that the distance moved by the two supports towards each other would be greater than the distance the weight lowered. The other 4 members would take the full load of the weight. The joins must have been really strong though. We didn't have any glue just string and rivets when we did this. I abandoned the rivets because I could not get them to work without folding and weakening the paper! My design was just one big triangle of 4 members and a central string. We probably used less paper but the weight was only 1.5kg! I could have used a design like this which my friend had but he only had one string in the middle which would bend the central member. Two strings at each joint would have been quite good. The weak spot was always the joins when we tried. That and 4 pieces of string would not take 1000lbs!
my left ear loves this
Not only is that a strong bridge, but those tables are pretty hefty as well!
It's now 2021, and my son finds this video to do his own paper bridge project. He was born in April of 2008. Crazy.
How in the world is it possible to make something like this last under such intense pressure with only paper/tape/glue?
physics
paper has the same characteristics like steel. That's the reason why you can use paper for that

it used to be a tree remember
the best answer
Construction genius! Anna will be a BILLIONAIRE some day. Greatly impressed
Are you sure?
If she applies herself like she has done here....yes! Absolutely sure.
Most likely a "hundred-thousand "aire
that's not how capitalism works. She might make someone else a billionaire and she will get paid a small wage in comparison.

Cool! My bridge held 279 lbs and only weighed 0.48 lbs, built from paper and glue in 2002
Are the blueprints still around? Just looking for inspiration in a bike frame build
That awkward fist bump lol.
yeah fist bump is defiantly not a girl thing
Definitely, not defiantly, hope the hundreds of people that misuse this word might learn something today.
Girls used to fist bump authority figures all the time, then one day, they all defiantly refused.

in my school they made us do this too but with no glue and only 1 sheet paper
in my school they made us do this too but with no glue and only 1 sheet paper with out tearing or cutting
Same
Wow, That's freakin' amazing!
@Lucas Warda fax
if that guy did not bump it who knows what it would have held
My school has the same tables! :D
How many members are there in the top ?
Blueprints please
That teacher seems to command a lot of respect from his students. Good to see.
How did you make the cross member/gusset that holds the truss together?
Congratulations. Excellent!

only reason it lasted was cuz of the plate underneath the paper, without the board it would die
It was Plano East 2008 ???

so true thats fucking HALF A TON. litterly half a fk;n ton!!
he's trying to weed out the idiots that haven't reproduced yet...
How is this possible it's only paper?
I just want to say Anna Gu you can break my bridge any day baby. gigity gigity allrighttttttttttttt
How did you construct the tension members? you said you used 20 pieces of paper, but how did you connect them all? just folding and gluing?
@Gregorybot what did u come up with? If I was there I would fold the paper lengthways mountain then valley until the whole sheet looks like a fan and if u suspend it like in the vid it would be pretty strong!
2020 anyone...?
Just plain amazing, never knew paper was that strong.
wow, thats amazing!!!!!
Why the tension members are V shaped and compression members circular?
What a jerk! That stupid prof. broke the britch with his arm!
Do it again!
It could hold way more!
I was wondering how you mixed the glue...
My education sucked ass
I just watched a video where bridges made using wood held like 1/50th of this weight. How is that possible?
composite structure with a lot of glue... get the fibre and glue working together and you increase strength...
all that brainpower to make paper bridges that hold 1,000+ lbs, but no weights bigger than 25lbs... They knew it would hold 800, why not grab some 45's to make room?
the geeks couldn't lift them while seated ;)
Pulling from a single point like that isn't testing the whole bridge, it's testing the structural integrity of that point only. If the weight would have been 3 inches left, then what?
if your mom had testicles, then what?
it's stuck together with my man goo.
it was 1060 not 1071
+Rajatkamal Polisety probably 1071 counting the weight of the hook and platform the weights are on
true
at the end he said add another 10 on it as you'll hear and the kid does it and one second after is falls, idk where they got the extra 1 pound tho..
Karlo Bistrički no
Rajatkamal Polisety the dock maybe
how much does the platform weigh?
so cool i have to build one and that is awesome.
hey how did u make you paper nails?
This is awesomely awesome!
oh shyt.....she should get into origami =O
I just realized that I haven't commented on this...Congrats Anna! about a yaer late...It's lauren by the way :)

Hello,
We are 2 french students and we would like to talk about your experience for our project
Have you got a mail to discuss ?
1060 not 1071 and how can paper hold that much
Go on Ann < insane weight for a paper bridge.
what the hell kind of paper is that? :D
Dunder Mifflin.
It`s not very realistic. I think that`s not paper.
howd u calculate the extra 11 lbs?
the way you stacked the weights was very dangerous.
probably the weight of the chain and base
hi anna, ur project was remarkable.
wish i cud chat to you about the specs.
why not use water ?
Best part (that nobody has noticed yet) is that the bridge could have taken more weight if the moron professor didnt nudge the bottom chord with his arm. LOL
awesome, sweet bridge
that was exciting, for real
BOOO!! Plano WEST
GO PLANO SENIOR!!
My son said the same about both of your schools - (Allen)...
😵😵😵😵😵😵😵😵😵😵😵
My project is the longest span as possible 8 papers 16 inch of cheap scotch tape record was 6 ft
Yeah!
Wow...great bridge.
On top of that Anna's kinda cute.
that wud be insane, although i wouldnt make it a car bridge during a thunderstorm
hey guess what i think . i think that they putted some (iron or something hard) inside the paper other wise it wouldn"t hold that many pounds .
I do think the layers were probably glued together and allowed to dry, rather than just rolling up paper. This would allow a papier mache' style arrangement. I've seen pens made of recycled paper that were pretty strong. Almost as strong as a plastic pen or pencil.
Now the central member wasn't taking as much force because it had a mechanical advantage in that the distance moved by the two supports towards each other would be greater than the distance the weight lowered.
The other 4 members would take the full load of the weight. The joins must have been really strong though.
We didn't have any glue just string and rivets when we did this. I abandoned the rivets because I could not get them to work without folding and weakening the paper! My design was just one big triangle of 4 members and a central string. We probably used less paper but the weight was only 1.5kg!
I could have used a design like this which my friend had but he only had one string in the middle which would bend the central member. Two strings at each joint would have been quite good.
The weak spot was always the joins when we tried. That and 4 pieces of string would not take 1000lbs!
:-o Wow! Spechless!
Gees This is the record from 1690 UPDATE PLS
pause at 00:00 and press up arrow on keyboard and left at the same time have fun :)
if i would do bridge it would fall from weight of that table...
Kilogramm please!
The Hat Whats the factor? ^^
Karlo Bistrički thank you!
type this in a browser "convert 1071 lbs to kg"... you can do these conversions in most browsers...
"paper"
viasevenvai read the description
Methinks mostly glue
I'm gonna ask my science teacher if we can do this for fun
that guy got hit by the falling weights!! LOL
Smart and pretty! Go girl!
#WomenInEngineering
wish I was Asian
When paper lifts more than you
Now make a paper airplane and see how much cargo it can hold.
So smart, yet so dumb...
What's the table rated for?
Is that really the best way to test the bridge?
just trying to get likes
from plano east 09', lasted 135pds :P
my right ear is jealous :b
lol
the guy pushed the bridge
Its look fake
I say 25 pounds is a win
This thing is mono
Fail fist bump at end
I have this challenge at my school... didnt go well ):
Lets say someone may or may have not gotten an F
the man runs it at 05:23
I have to make a bridge of 10 papers and glue for school, freakin impossible. >:|
thats crazy
5:24
i got 97 but it was 3 inches tall
capper dapper
"About" 485,797428 kg (or about a half ton)
