Making and Testing a Spaghetti Bridge!

[@kaapacityofficial]

Going to use this as a model, thank you so much! Edit: I WON THE SCIENCE FAIR AAAAA THANK YOUUUUU

[@bloop_official]

I'm gonna make it for science fair too! You got any tips?

[@ahmedtareq3787]

Your video helped us a lot during design phase, thanks! ❤❤ Edit: I won the first place in the competition, the bridge weight was 390 gm and held 58.3 kg before collapsing 💙

[@potatz_mag4375]

hey there!! may i know how many packs of spaghetti you used? did you follow the design exactly? :D

[@modz9816]

Ohh congrats, am doing a spaghetti bridge for my design project and I might just go with this design 🤔

[@ahmedtareq3787]

Hi@@modz9816 *Using this design will be recommended for sure because Here you have an arch representing the upper cord of the bridge, Arch shapes always convert shear forces projected to them into normal axial compressive forces, this is the greatest advantage you get from arches, in order to achieve this and get a 100% rigid, self-supporting arch, you should apply the chain test on your arch design and check if it's completely within the standards. *According to Bending Stiffness Equation (B.S=EI/L) 1- I really recommend increasing the moment of inertia (I) of the bridge by increasing the depth of the lower cord, you can use a rectangular section for this case, this would increase the resistance of your bridge against deflection. 2- You can increase the modulus of elasticity (E) by using superglue or epoxy only if it's allowed, because this would be a direct change in spaghetti's mechanical properties. 3- Shorten the length of your truss members as possible as you can, this would give you a stiffer bridge. GOOD LUCK... ✌😊

A friend and I made this bridge with .7 spaghetti. Turned out amazing, even though our craftsman skills are not the best, and because it was our first time making something like this it didn't stand the weight of the video, but amazingly it held 10x its weight! be free to try it, it's easy to follow with the blueprints and requires a small budget. (We spent around 12 $, we used .7 Spaghetti from the brand Barilla). I have to say I'm amazed and thanks for the fun time of building it, it turned out way better than expected, definitely worth the struggle 9/10.

[@StructurePlanet]

Thank you for the comment.

[@potatz_mag4375]

how many pack of spaghetti did you used?

[@andrewprahst2529]

So I'm trying to understand the maths behind the dimensions. Can someone help me understand? The middle rectangle immediately caught my eye, since it seems to fit two equilateral triangles in it perfectly (quite a strong shape), which would means the height of the rectangle is exactly sqrt(3) times the base. Since the base is 12.75 units, that would make the ideal height of the rectangle about 22 units tall, but the directions say 19 units. The height length is "19cm clear" instead of "19cm center to center" but it doesn't look like the bundle of 15 strands is really 3 whole centimeters even if that mattered (since the triangle sticks are clear rather than C/C too) I imagine the centerpiece makes the rest of the bridge fall into place. Is this small difference to compensate for some other part of the bridge? I understand its a small, maybe negligible difference, but I assume the numbers came from somewhere and they aren't arbitrary. Thank you.

[@bubbleguppies_v]

what is the bridge called?

[@jesseric806]

may i ask its relation to equilibrium? how do you think it works without a support underneath?

[@PenguinzPlay1]

Where did u go?? Why don’t u post anymore??

[@Valle_kuk]

Hi! So i’m doing a science project in school with building a bridge with pasta just like you do here. But the thing is that the bridge can only be 10 cm wide and it’s going to be over a 50 cm gap. Can i still try and do this like sketch and build the bridge with just some different measures? Or will it not work good at all because it should be able to hold 2 kg and we Will not be able to also have like wood when the 2 kg is standing

[@jillianbell2846]

Would like to try this, but I cannot seem to download the PDFs. Please help!

I just tried it and it worked fine for me.

what are the some of the other measurements for the bridge like for the bottom plan and the top plan

[@StructurePlanet]

All measurements should be on the PDF from the video description.

[@ryantaylor146]

how would you calculate the forces of the members for say 100kN directly at the top

[@StructurePlanet]

I would use a computer program to save time but there is a hand calculation way called "method of joints".

[@ryantaylor146]

@@StructurePlanet im looking up videos on that, its just a little confusing because all of the examples are much simpler trusses

[@StructurePlanet]

Haha yes. I haven't used that method in ages.

[@loy2541]

does having the two sides tilted stronger than if they were parallel?

Could I use .7 spaghetti? There's no bucatini where I'm from

[@StructurePlanet]

Yes, as long as the cross sectional area of spaghetti remains more or less the same.

A truss bridge.

[@tej4957]

What formula have used to calculate the height to weight to length ratio of the bridge.

[@StructurePlanet]

I didn't use a formula, if there is any. I just used a PDF editor to draw the 2D lines to get a reasonably looking bridge.

[@simonadebesi9346]

Congratulations, look so nice also strong👍, but if I want to participate in the pasta bridge competition in school, what should I do for a stronger bridge? Which point shoul give more importance?

[@StructurePlanet]

Well this type of pasta bridge may not be suitable for major competitions. For those, they usually use half a circle as the shape since arches are strong in compression and that can compensate for pasta strands being weak under compression and they usually use epoxy instead. An important item to look for is that the elements of the bridge that will go into compression have to be braced along their length so their compression capacity increases. If you look at this bridge that I made, the top elements are braced by plan bracings and the failure was where I didn't brace the top chord. I hope this helps.

[@simonadebesi9346]

@@StructurePlanet yeah it helped thanks a lot. You are best dude. Also i did not mean very big competitions our University doing each year and i am not sure but probobly 30 kg is nice to Carry. İ Heard best one is arch half circle type for this before you arr right. İ need much resarch i think. Thanks a lot Man. 👍👍
