This is quite an interesting popsicle bridge video. The maker claims it is the “ultimate popsicle bridge design” because it held 600 pounds. He also states in the description that he spent a large amount of time optimizing the Warren Truss. This is also probably part of his “ultimate design” claim…
Garrett-Jobs well done – interesting site and information!We built a 1/8″ scale model bridge just like the bridges we build for production. We successfully loaded it with 345 pounds with the weight being distributed all the way across the middle. Do you know of a formula where we can figure out that weight capacity for … Read more
I built this popsicle stick bridge to complete my short popsicle bridge series. This bridge uses the Howe Truss design. Previous to this I had built bridges using the Pratt and Warren trusses. This bridge was 13.5 inches long and used 50 popsicle sticks. It ended up holding 117 pounds before failing.
This bridge is supporting 191lbs of weight. It didn’t break, that was all the weight we could fit in the trash can. I believe this is close to the maximum load it could hold because the platform the jig is resting on was significantly bowed. The rest of the structure was rock solid. The construction of the bridge is popsicle sticks
This is the updated design of my Short Pratt Truss Bridge made from popsicle sticks. The only difference was the addition of 4 more popsicle sticks in key areas. I doubled up the angled sticks on each end, and made the lateral bracing into an X shape rather than a zig-zag pattern
This popsicle bridge was made from 58 unmodified popsicle sticks. It was 25 inches long, 4 inches tall, and 3 inches wide. I used only Elmer’s white glue to build the bridge. It weighed 86.5 grams, and held 45 pounds. Its efficiency score was 248. Build This Bridge I redesigned this bridge from the earlier … Read more
I just found some old photos of my first ever Science Olympiad bridge from 2000. The bridge weighed 58 grams if my memory serves me well. It held the entire 15kg with ease. It probably could have held 100lbs because it was so overbuilt. This was at my first every Science Olympiad competition at Gordon … Read more
I have a bridge I built for a physics for engineers class I’m taking in cegep (QUEBEC). My partner and I didn’t have much confidence in it, but it blew the competition away! We primarily focused on keeping the weight of the bridge down. The bridge weighed in at 211 grams.
I built this bridge for the 2005 Fernbank Science Center bridge design event. The bridge spanned 16 inches, weighed 37 grams, and held 346 pounds. That puts its efficiency over 4200! One commenter said, “So if this bridge weighed one pound, it could have held up my car.”
