The bridge was more stable than the cameraman.
ikr,the camera man is trash
I think the camera man was going through a withdrawal of some sort😂😂 the way he was breathing and shaking 😂
omg ur on point haha,by d way care to aub guys i would be nice ty😅
👍
OH SNAP!... sound of sonic boom cause I said it so loud
Insane holding that much weight during a earthquake!
Anthony Cabrera underrated comment
These are so frágile on earthquakes... If edges separate enough do to an oscillatory quake the bridge wont broke. Just fall complete. It always happens... Axes mst be really long to allow movement of given buildings
Lmao
Are you Referring to the cameraman?
LOL
I entered this contest when I was in college, it is a great challenge for engineering students to get off the CAD software and actually build something and test it. We weren't allowed any metal pins though, only popsicle sticks and white glue, anything else used was a disqualifier. I still have mine hanging in my garage as inspiration. This group did a great job.
:)
They did outstanding…they better have gotten an A on this one 😁
how did it perform in the test?
@@cabletie69 if memory serves, we held about 2000lbs of downward force on the centre beam. Designed a gull wing truss like this...'IAI'...It nestled tight below and between the outer supports, and transferred the forces directly to the rig itself keeping the majority of the structure in compression rather than tension. We also pinned each connection with toothpick sized pins to strengthen the load bearing joints and dovetailed each length of popsicle stick so that they didnt slip where they butted against each other.
@@johnnybgoodbeesandbarbecue5788 impressive result! Nearly one metric ton.
This is the type of stuff that prooves if you actually learned stuff and were not just there to fill seats
Not exactly. Its a group work & inside the group there are always teammates who just fill seats.
@@yureino SHADE HHHAAHAHAHAHA
Haha 🤣
@@yureino If you're lucky, those bench warmers will offer to pay money. But most cases they do nothing and still expect to get credit for the group work.
@@yureino nah it’s uni not high school. In univ- at least in my uni everyone participated .
I would replace the loading technique with pouring sand into a container to get a more exact failure weight
Also it will increase the weight gradually
You boys would be in charge of cleaning up then
Yer right! And would it be more accurate if the load was put on top(not bottom) of the bridge?
@@fultontracymendoza6149 the bridge is designed around the idea of the load being applied like this though..
Do you realise how much 120+ kg of sand is though? Just not practical
can we all just appreciate that 50 or less Popsicle sticks held up over 280lbs of weight..???
yes, because thats what this video is
What kg 280lbs is?
@@okiriotaa4664 around 120 kg
ur saying 50 or less popsicle sticks can hold two of me?
@@Starnoch yeah
Hopefully this engineering student has found relief from his constant seizures!
Never have i been so happy or seen anyone so happy to see their project break....after all, it's a truss bridge, and we all are eagerly waiting for it to break at some point😃🙌🙌
I remember building a balsa wood bridge in secondary school.
I love engineering and two others in my group did as well. We designed a bridge that worked so well using designs that were really cleaver and fantastic.
In the end we ran out of bricks to put on the bridge, so we got the teacher to stand on it. Our bridge still sits proudly on the wall of records.
We set the record of 140KGs.
In my high school physics class in 1975, two students took their quota of balsa splints and laminated two beams. It was better by many orders of magnitude. They illustrated why we don't build truss bridges and captured the essence of composite construction which was taking off at the time. The dinosaur teacher disqualified them as "not in the spirit of the contest".
@@iverburl Right?

*_"Oh, you innovated too much."_*
Why do they always find the weakest link to operate the camera?
Most likely one of the profs. So chances are pretty good they know a whole lot more than you.
LOL you call this acceptable camera work for a record attempt, wow you have very low standards. If it is a prof then it looks like he's suffering from detox shakes, give the poor guy a drink.
well what other job do you suggest he do?
he's a damn engineering prof not a film maker
This was recorded at a University, I doubt they're going to bring in a professional to record a wooden bridge :l
The crazy thing is that the actually bridge part didn’t fail the sticks failed
That's what's going to be the source of failure no matter what, it's just about designing it to distribute weight across all of the sticks.
@William Lyon I think they mean the parts where the sticks connected, whereas the breaking point was actually in the middle of the popsicle sticks instead.
@Neal Head pressure will almost never be evenly distributed across a bridge
??? the sticks are the bridge, it's like saying an actual bridge didn't fail because only the cable snapped
What will melt your brain more than this is they had stacked the weight on top of the bridge it would have had a different breaking point, in terms of weight. It may have been less or it may have been more but having it distributed differently would have changed the physics.
I’m probably the only one here that searched for this video.
Tell me your story
I'm with GARLIC BREAD PROVIDER
@@levihuerta9393 I’m in a Poe class, and we were instructed to create a bridge from 1/16 inch wooden sticks. I searched up videos for ideas on what kind of bridge to make, and this unique design caught my eye.
yes
Damn was gonna say that but you stole it. Wanted to see what kind of bridges are the strongest in the world and I somehow stumbled upon this and it caught my eye and honestly glad I watched it.
Fine, I'll watch it, UA-cam.
Simon Well, at least I know now how to count to three on a university level.
FINE
Simon lol
Honestly
Same reason i watched it haha
The camera man was still high from all the adhesives used in this project.
It was plain white (PVA) glue like used in elementary school. No fumes or harsh solvents. You can eat it without ill effects. Safe for children.
If only they could also build a stable camera stand.
If only people realize that not everything is a proper video shoot.
@@PrincipalCowbellist doesnt need to be to hold a camera steady
cheers mate. it was 2012 (or maybe older)
Shake demonstrated that it’s earthquake
Also CONGRATULATIONS to the team who designed and built this masterpiece!!!
Wow. They added almost 111kg (244lbs) to the bridge before breaking. That's insane
Yeah, that's just insane. I'd not trust a 3cm thick and 15cm wide plank to hold that weight!
That means that I could stand on it and have 90ish pounds of leeway before it broke
Dam that about double my weight though i do not trust that it would hold me because of mass and the slight movement and vibrations our bodies give off
@@shrimp3486 yep a nail hanging off a wall could hold a car.
But applying any moment on the car would cause that nail to break off.
People underestimate, how strong every day objects are
@@2DReanimation Over that span it would hold that easily
Since 90% of these comments are disrespectful ill drop in to say good job breaking the record there that was impressive
76.4% you fucking idiot.
what record m8 ?
Anthony Cannon tried to resign and get my own team and also develop more but you know how engineering goes people don't want to see you on the top so they it do their thing

@@Loachie90 You must be big into humour Micheal?
This is pretty cool. I'm a EE so have no idea how a bridge works but as a different kind of engineer can still appreciate the work
Jesus Christ I am a bridge Engineer and this impressed me !!
With a focus where the load would be placed. It's cool
george waite is the load being off centre relevant ?
Seems like you're under qualified in this case. I am a design engineer and I was not impressed by this.
@@scientist100 username checks out.... not
@@victor8992 ok captain obvious.
I remember doing this same project in my 7th grade industrial science elective class, very fun assignment. A couple of the teachers had an on-going fun feud to see which of theirs could outperform the other and awarded the students with extra points for getting the highest load or breaking a record. Learning can be a lot of fun! 😁
You could select your 7th grade class?
Most satisfying video? I just wanted it to break. For real though
Of course I understand 😉 I won’t tell them about your UA-cam channel
Never expected you here lmao
Love your videos bro
@@vikramsingha2312 tf if I knew ur location I’d probably find lost boys in ur basement and verified UA-camrs which u captured
Very nice! That's about 244 lbs. I had to do a similar thing working with my young teen's his science class. Sadly, it was all balsa sticks and no screws were allowed. But we fell farrrrrr short of this. It's a superb way to learn about structures
I loved these experiments in college and high school. So much fun.
6:04 "that's 19 and 8... Soooo 26" Im not going over any Bridges in new Zealand from now on
Raphael Thorp He bad at math
So they actually beat the record by 7...
Lol, I noticed that too and decided to check the comments first before I commented 😂
Lost that little casio calculator. LOL.
19 + 8 sooo 26 with 1 as a safety margin for people who don't read safety limits for my NZ bridge - I feel safe here in NZ
Geez Zuss.... can the cameraman take some classes there???
Frustrating. Cameta did not focus on the truss and the weight.
the cameraman suffera from autism dude.. we should respect that!!
At least it’s horizontal
Well it ain't a film class
waxandwane iiiiiii
I remember doing this in high school metal shop. The difference though was you had to make this out of 2 meters of oxy-acetylene welding wire and weld each joint. So it was a test of your design and welding skills. Pretty proud to say I held the record for at least the 4 years I was in school.
My similar thing was to make a foundation using 4 index cards and 2 inches of scotch tape. I remember my group not wanting to take my idea so I went and freelanced it and had the best solution. Held every text book in the classroom. Its really an easy solution if youre even just a little bit mechanically or structurally inclined.
Thank you UoA, my brain will now be fighting itself for the rest of the day.
As an mechanical engineering student at Worcester Polytechnic institute in the early 1980s we did the same exercise. Turned out design and calculated load was as important as construction technique. We were not allowed to use mechanical pins. Some of the students even fashioned gusset plates out of the glue tube !
Great! That's really using the materials "at hand".
I did this exact same design project in the 1st semester of 2018 at UoA and thought I would clear up some common queries in the comments. First-year students are given 3 weeks and a limited number of popsicle sticks to create the structure. There is also a tonne of ridiculous spatial requirements between the two resting points which largely dictate the unsymmetrical shape of the structure. These shapes and joints could theoretically hold a lot more weight as the limiting factor is the grain of the popsicle sticks, almost all examples break transversely to the grain at the loading point. You may notice that this structure has almost excessive cross-bracing on its top to withstand the largely imperfect loading method. Structures without sufficient crossbracing fail almost instantly (like,
Necro post. =) That is Ok, if you asked me. It held 1087N @146g ~750:1. Caveat, maybe they were forced to use the bolts as junctions compared to most other engineering competitions? Did you have to do that? Did not even hit 800:1, let alone 1200:1 for same competition held elsewhere in world(usually with longer span). The next caveat is the 10g of glue limit as most other bridge competitions usually meter out the glue based on volume instead of weight as they use "white" water based glue instead of PVA(rather odd)so I do not know how this converts to other competitions(the one I did and thousands of others around the world) and they might have chosen this to PURPOSEFULLY differentiate this competition due to the age of the internet and ability to download files from other people and same goes for your stated misalignment of the footings which does not make a difference to anyone who knows how to build anything, but to someone who is lazy and tries slapping something together at last minute... yup. Also, the span used in this competition is shorter than normal which significantly helps increase the load numbers and strength to weight ratios.
Always a good engineering competition. The ball bridge drop test catch engineering challenge is even better along with the earthquake building challenge.
PS: No "I" beams built out of the popsicles makes this a poorly designed bridge as a competition example. Stopping the transverse grain splitting on the popsicle sticks is easy with a little glue and a shred of cross bracing against the grain direction.
Had me on the edge of my chair., Bravo well done....
Loved Statics. One of my favorite classes. You never see your surroundings the same after that clas.
good job..keep moving forward 😃
Nicely done, team!
Next assignment... Camera Stabilizer.
Wow that was both thrilling and educational..👍 nice work on the bridge..
Its good having fun and learned skills, and ideas. Wish all schools do same as this. Group project to enhance there skill, ideas knowledge and teamwork.
Probably not a good idea to be filming after a heavy night of drinking. The shakes can be a terrible thing.
Let's give the camera to the parkinson guy
As cameraman is a good engineer 😏
Haja
lmao
We did this in middle school, 8th grade... was a blast learning about tension loads.
Brilliant placing the loading point off center! And biasing it towards tension rather than compression! Wonderful.
Are you referring to the asymmetry ?
@@redreuben5260 yes the asymmetry. I believe the closer you place the load to the edge, the less moment you need to deal with.
@@Aheitchoo That’s fine for a static test but does it apply when a cement truck drives from one side to the other ?
@@redreuben5260 This certainly wouldnt work for a cement truck. But as a discrete solution to a discrete problem its clever.
Having done this in an engineering class in high school I have to note the way in which the structure collapsed which was via the load point only leaving much of the bridge structure intact.
I remember many spectacular failures, including my own bridge, in which the entire structure collapsed and failed.
I don’t remember any, though there could have been some that collapsed at the load point. Very fun to watch!
Man, that was a great bridge. Good job. I wish my bridge would of lasted that long.
-〉FuKzWiTiT〈- I would even cut my own tree down and even plant them to carrots enter that into the input output but they don't let me do that
This reminded me of a bridge I built out of balsa wood and glue in high school AP physics class. We ran out of weight objects(which were being placed in a 5 gallon bucket) and the bridge didn't break. I used the Roman arch principle as inspiration for design and placed arches along outer edges on both sides and in between the two outer rows perpendicular to them.
This is what saves life's. Keep going at it!
maybe they should offer a course in film making.
I almost got an epilepsy watching this video
U mean film shaking?

Engineering students.
I was wondering why he was using a calculator, would've counted that in my head low iq engineers
At some point you really stop doing little maths like that and focus more on other things like analyzing problems to determine what equations/methods to use.
Little engineering tip: never waste any time solving what computers can do better.
@@cosmosity1693 Because it's just as likely to have 13.24*pi. You don't know what will you encounter next, so better use a method that solves all.
@International Jujuman Miscalculation like that is like little grammatical mistakes. You don't correct people, because nothing is gained in doing so.
Truly amazing !!!
Awesome job !!!!
After I'm taking an Engineering course in post-secondary school, I'm starting to get interested into watching these videos xD
Wow, that tiny bridge held 1 and a half times my bodyweight. Hats off to the kids who built it!!
now can they learn how to operate a camera?
+TheRoguePhysicist lol
TheRoguePhysicist it is sideways idk what your talkimg about
That's for art majors.
They're engineers.... they can tell you how a bridge is supposed to be built but have no idea how to cross one
this was 5 years ago. People today still use vertical
That was so cool. Great project.
This reminds me of a paper bridge contest we had at school. We were given 10 sheets of paper and some glue to make the strongest bridge we could come up with. My design used only 6 sheets. I made a layer of paper folded back and forth in a zig zag pattern, glued the deck onto that and added a triangular "tunnel" to the bottom to give it all some extra strength.
That bridge not only spanned almost twice the length of all the bridges my classmates had made but also carried more than 3 times the load the teacher had set as a target.
You should habe build little paper cars and trucks that go over the bridge with the 4 paper sheets you had left lol
My bridge (2019) held upto 550N, very proud of my bad boi! 😅
The real winner is University of Aukland, 4M+ views
proud of you guys
Good effort! Reminds me of a competition we did at school to use just cardboard and PVA to build a bridge that span 1m. Its all in the glue :D
Dang an estimate of 1.2 kN and an actual value of 1.087 kN is hella impressive! Nice job! Btw, it supported 111 kg!
I miss fun engineering classes. I had a beautiful bridge that took like 140 lbs to break and was something like 60g, made of balsa so not a fair comparison to popsicle sticks
Well done. My brothers' 1st year was 2001 his group won their year with 103kg and a simple design level span off center loading point. I was 1st year in 2005 and my group won our year with 114kg (I remember this as it was Jonah Lomu's weight) we had much more difficult parameters, similar to yours. uneven span, off center loading point and had to allow for a pipe to fit the truss and a certain point. I still have my truss in my office, it failed at the upper landing.
To everyone commenting about the camera shakes. This is from 2013. Digital stabilization wasn’t necessarily widely found on cheap cameras/smartphones.
Why it asymmetric tho
Edit:WTF,That thing is strong
It puts the load closer to being under an anchorpoint therefore reducing the stiffness needed to hold the weight up and reducing the strain on the structure of the bridge.
@@callumwyper now if only you can convince all that vehicular traffic on your bridge to distribute their loading per your optimized design...
Edit: I recognize that the design probably fell within the requirements of the competition, I just don’t agree that it’s an appropriate simulation of real-world requirements
@@SpamSucker What if it is just an estructural part of, for example, a machine, such as a crane.
It is quite easy to be a smartass, not so much to think outside the box...
@@SpamSucker i don't see anyone who say that it's an appropriate simulation of real-world requirements
@@callumwyper We had the same design problem at QIT (to span two points with a sheet of paper) only the load had to go through the centre. I got 100lbs which was the record in 1975.

Someone had to lift the weights.

Very impressive keep up the good work
Are you allowed to grind the sticks to dust, mix the glue into the dust and then coat the screws with the mix and make the bridge?
We did something like this in high school. Our team lost on a technicality. The winning entry was demolished during the test. We took ours home.
look something worth filming! Quick get the worst cameraman we can find!!!
I suppose he was the best cameraman they could get.
/r/killthecameraman
Call me misogynistic, but the cameraman must have been a woman. lol
Justin Thyme you could hear his voice, dumbass
@@justinthyme5730 I think we all know a man is more likely to be worse at filming than a woman.
the bridge folded in several location, this is a good sign that the distribution of the tension was fairly good. It would be even better if the bridge literally exploded everywhere at the same time, meaning that all the efforts were all over the place, evenly.
when I did this exercice back then (with spaghetti), we used 2 buckets of water and poor in from one to the other gently, then weight the bucket after the bridge breaks. Seems more convenient than the loads you are using.
good show, loved it.
Thanks.
I enjoyed it too! From what I can see, the joint failed. It would be interesting to see how the bridge holds up if the joint could be a single piece of cnc'd aluminum. But then again, the connection to the internal member may be the next point of failure due to the shear value of the bolt in the Popsicle stick. The pre-stressing of the bridge is a clever idea!
I wish we had got this much fun learning in my days in engineering college.

As a woodworker I wonder how much the wood comes into play. Depending on what part of the tree each stick is cut from can have a big difference in strength. Old growth trees will have tighter growth rings making it stronger compared to farmed tree with wider and weaker growth rings. The PVA glue too. A rough piece will stick together better then if both pieces are smooth. 🧐
Exactly what I thought, I would definitely treat the wood with some sand paper at the areas where glue is applied. The part about using stronger better stick is probably part of the competition, I am sure the teams built dozens of prototypes before ending up with final design, so they definitely noticed that some sticks are stronger, the glued parts tend to fail less if the surface is rougher etc. But my guess is that the design is 90% of the strength.
I am more mad about the weighting process, first off yoj should apply weight on the top of the bridge, it would carry much more weight, or dont call it a bridge but a hanger or something, but it is dumb because with a bridge you distributing the weight over the whole construction, where with a hanger, that spot where you hang is the most stressed. But the worst part is adding weights, why keep adding 10kg plates, why not add like +1, +2, +3, +4, remove and add +10, they failed at +10 but the limit was anywhere from +1 to +9. Also the dude is not very gentle adding the 10kg plates, so the inertial force might have actually peaked at few kgs higher if the plate was actually slightly dropped. I dont know, I would personally load it with a hella strong wire that is slowly spinned onto a coil, with a peak force meter in between.
At least the video wasn’t recorded vertically
Brilliant camerawork
That was amazing well done people :)
I haven't the slightest clue what the hell this is or why it's in my recs, but they sure seem excited.
Please redefine the wording to the video title - This is not a test of a bridge - but the test of a central load hanger
Excellent camera work.
superestructura. felicitaciones. Buen manejo de las cargas.
In highschool I remember we did this and I won for efficiency (weight of bridge vs payload) with a 19 gram bridge that held over 1500x its own weight. (yes that's a bit over 50 lbs)
Basic rules: 30 cm Span, 5cm wide "roadway", using only 1/8" basswood and what I think was PVA glue. It was some white hobby glue I forget exactly what it was.
Load simulated by 8cm x 4cm wood blovk with a hook on the bottom (where the bucket hang from), which is rotated slightly diagonally to spread the load onto the sides.
Also, no laminating 2 pieces together (except for where the "sides" met the
"roadway"), and there were a few other specifics.
this bridge held up 110 kg or 242 lbs
Only as strong as the adhesive!
nytom4info
Call me crazy, but I'd use a bucket and slowly fill it with water. That would allow for adding the last fractions of a N in small increments.
Larry Scott how would you keep water from spilling everywhere?
If it was really important, there are digital force gauges that can measure precisely how much force was applied before failure, and even create fancy graphs of the load over time.
Nnelg
A sufficiently large bucket only has to be suspended 2-3 cm. And a digital load cell that records data, rate of increase, and maximum load. Even if the bucket spilled.
The some what large weights don't permit a fine granularity of increase.
Either way, the very high engineering of the truss seemed to be determined by an unreasonably crude application of load.
What if 1st and 2nd place were separated by 10 g? And the 3 second count to add more? A steady stream of water adding a given load per second, which can be regulated to appropriately slow, would seem to be more objective. And the rate could be digitally recorded as well.
IMO
If the top two are separated by less than one Neuton of force, then it's simply a tie. This isn't some inter-school competition with a cash prize involved, it's a class project for first-year mechanical engineering students. It doesn't really matter who wins, the point is just for the students to put what they learned in class to a real-world test.
Nnelg
Well mechanically, water in bucket is simpler. And simpler is good engineering.
We did a similar project in high school physics... you received 1 Manila folder and were told to span a set gap. (I think it was 9 inches). Had to be an A frame type with a centered load. Smart folks used different glues, one even used hollow tubes and filled with hot glue. Meanwhile i honeycombed my main struts and carried twice as much weight as the solid strut with 1/5 the weight
Damn
Well Done! Congrats! Beats my university balsa wood bridge design and break some 29 years ago! Is this till holding the record some six years later? In any case, a great memory for students. I remember my project and contest all these years later! Months later we did a 20 foot span steel bridge and did a little better.
when you make that out of 10 sheets of 8x11 normal stock copier paper. call us. No joke that is the final engineer bonus test we had to tackle.
Go on.. 😂
Are they counting out "1, 2, 3" to announce that the bridge has to support the weight for three seconds for that weight to qualify?

Just passed high noon!
my education fron Eng School served me well. Our bridge back in the 70s was a hardboard box girder.
Well done guys!
its 2019...is there an Actual Bridge of this Design?
I think it's not good for sea link purposes becoz there is too much structure beneath the road level .
In my opinion: the big problem was the V-shape where the load was attached. The v-shape produces tension outwards to the left and the right of the bolt. I think a curved shape in dimension of the bolt would be better.
Lol Idk why I'm replying to this 4 years after you made the comment, but if you look carefully at the joint at 1:35 right before the bolt is placed there is a curved connector piece of wood that straddles the V
They have curved chop sticks?
@@warsson1 put them in water and bend them the way you want
That bridge is impressive!
Back in my day we used the workshop presses with load sensors to test. What’s with adding weights by hand?
The intro says the students had to make an estimate before the test. I'm just curious how accurate the estimate was.
I think it said the bridge was estimated to hold 1.2kN but it held 1087N.
What a truss ! :)
what is truss?
+Carlos F Ruiz
Why are you even here?
+Carlos F Ruiz supportive system, could be a bridge. people are mean
I've never heard what truss is. That's why I'm asking I think that is from New Zealand or maybe.
+Carlos F Ruiz I'm sure there are trusses there too, but you aren't an engineer, and as long as your house or bridge doesn't collapse you're cool. It's just triangles formed to make support systems, triangles are the strongest geometric shape.
Impressive. But, is there a video on the design of the Truss Bridge and the design factors used to achieve this ? ( or do I have to study at New Zealand Uni ? ) ha ha
I don't have access to the rules of the competition, but it seems to me the load should have to be applied at the midpoint (ie: equidistant from both side supports) to ensure a level playing field for all contestants.

I wish more schools did this. Too many of the "top" universities focus completely on analytical work.
We did this in my high-school. Someone made a bridge that withstood the max weight we had so we made a kid stand on the thing underneath and it still didn’t break.
of course i get this on my recommended after i have a bridge building competition
