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?

[@rowis]

@cellophaan Zowel de foto's als de film is eigen beeldmateriaal! Maar we hebben het bezwijken van bijna alle bruggen gefilmd.

[@jporp84]

Hello, does anybody can explain me how to make the connections between the legs?

[@rowis]

@kleinernilsliebhaber the widt of the bridge is 1 meter and the angle is about 30 degrees

[@B3N1GMA]

what type of bridge is this? If truss, then what type of truss

[@rowis]

@DanFrederiksen All spaghetti rods are glued together. The tubes are hollow to save weight and the connections are massive.

[@rowis]

@zocker057 probably you can use thinner tubes to reduce the weight of spaghetti.

[@DanFrederiksen]

was it glued together?

[@zocker057]

How many kilogram Spaghetti did you use all in all?

[@cellophaan]

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?

[@msHLC96]

how much did your bridge weigh?

[@grahambennett9100]

how much spagetti did u use

[@rowis]

@harleygaray We didn't use any type of treatment. We just used regular spaghetti from the supermarket.

[@terenfro1975]

Student did not make the road structure very supported at the edge. This was a roof truss roughly made to look like a bridge.

[@rowis]

@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.

[@zocker057]

@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

[@rowis]

An English subtitles is now available!

[@rpearce14]

How much did it hold

[@welshpete12]

Just over 85 lbs , a remarkable achievement !

[@rowis]

@B3N1GMA It's a truss bridge. But specially build for one point load.

[@cscsamsung9749]

ขอบคุณครับ เป็นการทดลองที่เป็นความจริงที่คนนอกห้องเรียนยอมรับว่าโครงถักแบบทรัสรับน้ำหนักได้มาก และขึ้นอยู่กับวัสดุที่จะนำมาใช้ เช่นไม้และเหล็กมีคุณลักษณะไม่เหมือนกัน การรับแรงย่อมต่างกัน...

[@rowis]

@msHLC96 the weight of the bridge was 862 g (1.9003847 pounds)

[@rowis]

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.

[@rowis]

@addi1403 The span of the bridge is 1 meter

[@rowis]

@DanFrederiksen The epoxy is much stronger than the spaghetti so we want to use glue instead of cooked spaghetti.

[@msHLC96]

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. :)

[@hunterpmitchell]

how the heck did you build that thing

[@lucianorosa8349]

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.

[@cheeterable]

which glue you used for that oversized construction

[@rowis]

epoxy glue

[@snow_dogs]

38 kg is neem ik aan best veel?

[@rowis]

@DanFrederiksen The tensile forces are absorbed by the glue in the joints.

[@DanFrederiksen]

couldn't spaghetti be used as glue?

[@deibynaranjo4449]

Desde Colombia. Por esperiecia enpirica le digo SOS bueno con las estructuras de puentes

[@professordeb]

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. ;-)

[@rowis]

@zocker057 We used 0.8528 kg spaghetti.

[@rowis]

@rpearce14 it's failure load was 38.8 kilograms = 85.5393577 pounds

[@rowis]

@sn0wD Ja... 45 keer z'n eigen gewicht en goed voor een 2e plaats. Dus best veel!

[@rowis]

@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.

[@AlexFrezCorrea]

Which kind of glue did you use?

[@rowis]

We used epoxy glue.

[@DanFrederiksen]

@rowisj if the spaghetti is strong then why in joints too..

[@lucianorosa8349]

force in the worst diagonal = (fvA - force diagonal)x sen 45 ; fvA=fvB = ft/2; after find the area minimum, tesc flambagem

[@rowis]

We used 0.8528 kg spaghetti.

[@DanFrederiksen]

@rowisj why not..

[@msHLC96]

@rowisj alright cool I'll try it, thank you :)

[@JerreldenHarder]

wtfuuu 38 kilo

[@Superchickenman159]

breaks at 3:00

[@monkeydunkey1]

38 kilos is 85 pounds

[@elisevonk537]

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.

@rowisj sig figs dude...

say wat? mabey next time in english!
