2013 Spaghetti Bridge Test

Students in Prof. Marietta Scanlon's Materials Sciences class, at Penn State Lehigh Valley, built bridges using spaghetti and hot glue. To test the strength of the bridge design, a bucket was attached to each bridge and measured amounts of sand were poured into the bucket at 10 second intervals. The winning bridge design had the highest ratio of bridge weight vs. load weight (weight of sand).

    Interesting that most seemed to fail by compression in the top members, indicating that they had put too much material into the bottom members that were in compression, and not enough into stiffening the top.

    One reason the pasta might be failing so much under compression is that it’s easy to flex being so thin, so it’s far easier for it to buckle under compressive loads.

  • @shrikantc56
    @shrikantc565 жыл бұрын

    Main reason for many small member bridge was.... It got too many connection.... And if connections is weak/ fail than whole system tends to fail... But if u design with less number of join and focus on member itself that is member under going tension compression as we as flexural ur structure is gonna sustain... That is what happen with 4th bridge... It ultimately failed through member rather than joint.... So while designing anything joint shouldn't fail before member or else whole system is gonna fail....

    A fun and age appropriate activity for your pre-K's (any age, actually) would be to use popsicle sticks and hot glue to build first a square, then a cross-braced square and let them feel the difference in ability to flex the structures out-of square. Then build a box-shape structure without bracing, and also one with bracing. Again, let them feel how easy it is to collapse the unbraced box. If they're old enough, it's fun to split them into groups and have them build a box to stand on... the highest weight capacity wins!

Чтобы проверить прочность конструкции моста, к каждому мосту был прикреплен ковш, и отмеренные количества песка были вылиты в ковш с 10-секундными интервалами. Победившая конструкция моста имела самое высокое соотношение веса моста к весу груза (вес песка).

    Did something similar in school. It's FASCINATING to see the specific failure points and then trace back to where the design or construction could be improved. For anyone interested, here's timestamps of the moment each bridge failed: First Bridge: kzread.info/dash/bejne/h66hm5WKg6Wclrw.htmlsi=Dkr139lU2RLe3JVC&t=51 Second Bridge: kzread.info/dash/bejne/h66hm5WKg6Wclrw.htmlsi=Net_DKQV0dGEyEHj&t=65 Third Bridge: kzread.info/dash/bejne/h66hm5WKg6Wclrw.htmlsi=LfTtiWblM8xIvl-F&t=132 Last Bridge: kzread.info/dash/bejne/h66hm5WKg6Wclrw.htmlsi=6HHV_Yj8_Afm81Zn&t=218 Personally, I found it most interesting that it appears to be tension pressure which wasn't (understandably) accounted for. It looks like it's a mix of imperfect construction or lack of available margin to add structural elements (or shrink others because the size of the building material is fixed).
