Basics of Building Construction
was it glued together?
couldn't spaghetti be used as glue?
@DanFrederiksen All spaghetti rods are glued together. The tubes are hollow to save weight and the connections are massive.
@DanFrederiksen The epoxy is much stronger than the spaghetti so we want to use glue instead of cooked spaghetti.
@rowisj why not use carbon fiber while you're at it then.. : ) epoxy is cheating
@DanFrederiksen There was only spaghetti and glue allowed, so epoxy glue was the best option. Without using glue you can never make a strong bridge.
@rowisj if the spaghetti is strong then why in joints too..
@rowisj why not..
@DanFrederiksen The tensile forces are absorbed by the glue in the joints.
Tof! Ik had me destijds niet gerealiseerd dat jullie ook bij de teambouw de tweede prijs hadden gepakt.
Is dat het beeldmateriaal dat de organisatie had gemaakt, of hebben jullie het zelf gefilmd?
@cellophaan Zowel de foto's als de film is eigen beeldmateriaal! Maar we hebben het bezwijken van bijna alle bruggen gefilmd.
what type of bridge is this? If truss, then what type of truss
@B3N1GMA It's a truss bridge. But specially build for one point load.
How many kilogram Spaghetti did you use all in all?
@zocker057 We used 0.8528 kg spaghetti.
@rowisj I ask because we have to build at school in grupos also a Spaghetti bridge
and the group where I am think that your bridge is a real good one.But we have only 0,500 kg spaghetti we are allowed to use
@zocker057 probably you can use thinner tubes to reduce the weight of spaghetti.
38 kg is neem ik aan best veel?
@sn0wD Ja… 45 keer z'n eigen gewicht en goed voor een 2e plaats. Dus best veel!
@addi1403 The span of the bridge is 1 meter
breaks at 3:00
@harleygaray We didn't use any type of treatment. We just used regular spaghetti from the supermarket.
how the heck did you build that thing
How much did it hold
@rpearce14 it's failure load was 38.8 kilograms = 85.5393577 pounds
@rowisj sig figs dude…
how much did your bridge weigh?
@msHLC96 the weight of the bridge was 862 g (1.9003847 pounds)
okay, so in my physics class we have to make a bridge out of any type of pasta and glue but the requirements are it must be longer than 12 inches, no heavier than 100 grams, and has to be able to withstand the weight of a bucket full of water hanging from it. Any advice?? Pleeease. 🙂
@msHLC96 You can use a truss bridge (see the 4th picture in google images). The best shape is to use a triangle, a little bit like our bridge in the movie, but than with single spaghetti truss members.
@rowisj alright cool I'll try it, thank you 🙂
@kleinernilsliebhaber the widt of the bridge is 1 meter and the angle is about 30 degrees
Beautiful bridge and near perfect form…great job! I predicted shear failure at the end–just too narrow. Bet it could have held 50% more otherwise. Re the above note though, carrying the conversion to .9003847 is meaningless. You can't weigh a dust particle to that precision! 1.9 lbs is close enough. 😉
you're right! 1.9 lbs is close enough… it was just google calculator that gives that answer. It was not just shear failure, the end of the bar buckles due to the compression force in that bar.
Maybe this could be your next challenge: 'Imtech promotes GreenTalent', a GreenTech ideas contest for a more sustainable world. As an ambassador I would like to invite you all to join! For more information check out the Imtech website.
Hello, does anybody can explain me how to make the connections between the legs?
how much spagetti did u use
We used 0.8528 kg spaghetti.
say wat? mabey next time in english!
An English subtitles is now available!
wtfuuu 38 kilo
38 kilos is 85 pounds
which glue you used for that oversized construction
Hello!! I'd like to get more information about this project of yours… because I'm quite interesed in doing my own Spaghetti Structure. Can you answer me these questions?: Which is the lenght of the structure? Which spaghetti type did you use? (Eg. Penne, Rigatonni, etc) Any advices?
Which kind of glue did you use?
Posting a foreign crap video on an English website. Great job, genius.
Had wel meer verwacht van de tu delft. heel slecht ontwerp. een hangbrug kan veel meer hebben.
Student did not make the road structure very supported at the edge. This was a roof truss roughly made to look like a bridge.
You can make all models you now ………………………………… but the maximum force is in the first diagonal near the foot.Ever colaps are similars. Ft/ndiagonalsx sen45 = force in the diagonal; 460Kgf/cm2=f/area; area = ……x, find the Moment inercia.
force in the worst diagonal = (fvA – force diagonal)x sen 45 ; fvA=fvB = ft/2; after find the area minimum, tesc flambagem <=460Kgf/cm2; after the find the area …………………. find the moment inercia minimum. In tresses we only have traccion and compression, only …………………..
ah at finally tu delft have earn some money from tax box~but weight + distance is more useful and same brand of spaghetti – and then some competition – anyone can participate how more how better found new constructions for steel bridges (shall be) (is meant) ~while playing with food and with so lot food banks – now is not much smart~oops sorry I did not known economy growing according to Rutte NOS RTL SBS (all that fake news) The number of Dutch families getting aid from food banks increased by 8 percent in the first half of 2019, compared to the same period last year, food banks association Voedselbanken Nederland announced.~congratulations – seems to me you only want read some story lazarus and rich man – but eeeeeeeeeee here is also today lot lazarus`s shall be not is the wealth in world or the specifiek Northern Hemisphere~them also goes helping education – but have said – at your first first appointment to hospital some specialist (do not matter what) – imagine how much you need peoples to reach specialist(and someone must cleaning his table and washing his clothes otherwise varkensstall (theirs own language))– and you want not that but still you want them not see now what for human you are
