Fall 2014 - Spaghetti Bridge Final Testing

Undergraduate students in the Statics course offered at the University of Texas at El Paso (UTEP) are required to build a spaghetti bridge as a final project. In this video, the students conduct the final test of their spaghetti bridge designs. A special thanks to teaching assistants Shafin Haque and Luis Varela.
Students must design a spaghetti bridge as a final project
00:30 - Bridges are weighed and measured
00:43 - The bridge must withstand a 2.5 lbf weight for 5 minutes
01:16 - All twenty bridge designs were unique
01:32 - Now lets break some bridges!!!
10:42 - Next Semester the load will be increased to 5 lbf
Now lets break some bridges!!!

[@ammariessa7424]

its not about Spaghetti its about engineering and physics if u can make something that can handle a lot of wight with something thin and izi to break its amazing, imagine if we used that instruction the winner did with iron thin bar how much of material we could save !!. same as building house instead paying a lot of money and u can manipulate the instruction to buy fewer material and hold as strong as the old design with less money u pay ! .

Welcome to engineering school... here are some things you should know: 1) we don't understand the transition of potential into kinetic energy and the concept of velocity as it relates to force. Ie: 5:13 2) we haven't figured out how torsional stress affects a structure because we stack weights on different sides. 3) we also haven't figured out a better way to put weights on other than closing each individual chain by hand. 4) who ever designed this competition should have come up with better testing methods. Just saying.

[@ramejpetmalu9150]

who else get mad of what he had done @ 5:13 😠

[@isaacvinas6676]

Me he dropped the weight on purpose😡😡😠😠

[@DillonK13]

probably because that was the winning bridge and it was taking all the weight they had. similar to the last bridge the video cuts out on. they start to push on the weights and throw their hands up because they dont know what to do.

[@jakefriesenjake]

He thought that the chain would snag on top of the other weight. It slipped. This is totally wrong. I would ever so gently release the weight. Some designs were so horrible. Lol

[@hwajeongkid25]

The dead load (weights) should be placed on the bridge platform to be distributed on all members and the structure might carry more weight. Placing it underneath will only stress a particular member, break it and may not reflect the actual load the truss can actually carry.

[@rubeushagrid4131]

Watch his biasness at 09:23, he just dropped the weights which is not the correct way to do it.

[@moonmanvic]

[@PabloDelafuria]

yeah they should use a bucket and fill it slowly with water

[@georgesadler7830]

DR. Stewart, I liked to thank all your Mechanical/Civil Engineering students for an awesome spaghetti bridge design as a final class project. These designs should help students understand real world structures. Professor Stewart, I watched and analyzed all 66 lectures. All these lectures are amazing. Statics and Dynamics used to be part of the Electrical Engineering undergraduate degree at the University of Maryland College Park. I took both classes at the old Catonsville Community College in Catonsville, MD in 1986. I review these two classes because I will be taking the Fundamental of Engineering Exam very soon.

[@garylosa435]

This is not how an engineer would put weight in this test/competition. Carelessly dropping weight would result in different kN.

[@medvidekmisa]

totally...utterly stupid...university of what is this?

[@zikari0]

toda la razón.

[@brainmind4070]

They should really let the teams put on their own weights. That way they have incentive to be gentle.

[@dlvr659]

These competitions at school were cool. I remember we used to do egg drops for vehicle safety and popsicle stick bridges for engineering.

[@carlmanis879]

what about at 5:13 he drop the weight

[@terenfro1975]

I started doing this back in 2010 with my classes. 70% of the grade is an engineering report on the design. 30% is based on a weight to load function. The weight is held on the road bed and not through a U bolt so it is more like a real bridge. The idea though is they can make an application and write a paper that describes. They also have to have a draft of the bridge in the CAD that we use.

[@ventiladordesuco]

The Flying Spaghetti Monster is very pleased. Science + spaghetti + reggae, very well done guys & gals.

[@YVO007]

It's the specific load baring point that gives in which means that it is more likely the materials not the design structure.

[@CalvinStewartPhD]

[@gustavoencarnacao544]

He can't load the bridges with assimetric loads. When he puts the chains in one side of the first chain.

[@AbdulazizAlmawash]

Why triangles on the bridge..? Is it to kind of distribute the pressure (energy) equally across its parts so if we were to measure the pressure on each half from center it would be equal?

[@wishiniwasfishin8164]

When I was in a bridge competition we had a plate that was connected to a pail that we would gradually fill with sand. It worked quite well and distributed the weight equally. The way they are doing it in this video has too much pull in a small area. And the weight increments at some point are too much to add .

[@ChristopherStClair-mw1gq]

Awesome we did this in 5th grade but with popsicle sticks and wood glue proud to say our groups bridge held over 150lb before we ran out of weights and had to start using text books. Never broke we estimated it held a little over 170 lbs.

[@phillip_iv_planetking6354]

This is awesome.

[@momonjaa]

After that, they had the best spaghetti party.

[@drkjk]

Is point loading really the best way to determine overall strength of the design?

[@brainmind4070]

drkjk If it's specified in the rules of the competition. A structural solution is designed around a load or loads and constraints. They're not trying to design actual bridges, just carry the most load held at the center point between a span of a certain distance. The bridge should be designed with this load case in mind. If the competition allowed the load to be held anywhere on the span, all the teams would apply the loads closest to the table, which would defeat the point of a bridge-building competition. A point or line load at the center is the most efficient test of a bridge design.

[@patrickgoldberg7915]

Bridge design

[@edenwilliams9884]

although this method isnt the best, it is about centered statics. they would see difference results it the weight was hung different and this would also cause a change in design as well.

whats the rule on building one? type of glue? coz thats what make it stronger.

[@sambrewer2306]

Brain mind u know what u are talking about. I did really food in school making a tower w balsa wood and glue that went around a pole and had to be a certain height and weight. Then put weights on verticle board until crushed. I used triangles and a porta glue and sanded clue to lose the wiet but ensured good connections. I would be interested in trying a bridge builder app same as this. Would make great app. If calculations were correct.

[@sambrewer2306]

[@cyrusIIIII]

Where can I find the rules and manuals for this type of competition?

[@CalvinStewartPhD]

Several universities publish rules for Spaghetti Bridge competitions. Search google. Make sure to ask permission before you use them.

[@brainmind4070]

Or just make up your own. 1 box of x-brand regular/thin/angel hair/etc... spaghetti or equivalent net weight (in case of broken noodles), 1 bottle of glue (or reel of fishing line) of certain size and type, span distance, load application location, method, and increments, time bridge must hold between weight addition. I would try to find a method for applying weights better than they did here. With weights hanging off the sides like that, it has the potential to torque the structure in unpredictable ways or create shock/acceleration loads if weights shift. Also, avoiding shock when applying weights would be necessary. Having teams apply their own weights and having an official (ideally multiple) with a stopwatch (that they press once the team member has ceased touching the structure) can help mitigate claims of unfairness.
