- Ultimate Popsicle Bridge ...
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…
- Warren Truss
The Warren Truss was patented by James Warren in 1848. It has been around a while. It is one of the most popular bridge designs and examples of it can be found everywhere. The Warren Truss uses equilateral triangles to spread out the loads on the bridge. This is opposed to the Neville…
- Old Model Bridge Trusses
I found pictures of some old trusses I built for Science Olympiad bridges. Most of these were built in the 2003-2004 school year. I thought I would post them to give examples of how these trusses could be used in model bridges
- Nic’s Popsicle Stick Br...
Nic’s design held a weight of 224kg and had a final efficiency of 1020. It did not shear or snap at any member, but bowed in the second third of member C-E. This member did have angled bracing to stop bowing and this brace did not snap it was only the glue joins in this [...]
- Toothpick Arch Bridge
I just completed a new toothpick bridge that’s quite different than my last one. It’s an arch made from curved trusses, formed once again with toothpicks and wood glue. This one won’t be tested either (sorry!) because it was made for a friend who creates custom action figure dioramas. But I designed the bridge to [...]
- Greentop Road Bridge
Pictures taken on October 5, 2006. This is only of the few historic bridges that is still in use. I am glad to have found it. The metal does not look in great shape, so I hope it sticks around for a while. More than that, I hope that when it is eventually replaced that [...]
- My 1st Bridge
I just found some old pics of my first ever Science Olympiad bridge. These photos are 7 years old. Many props to my mom for keeping them. 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 [...]
- The Whooping Creek Bridge
The Whooping Creek Bridge was originally built in 1928 (According to here). Unfortunately, the bridge was closed in May of 2006 after a DOT inspection. 5 months later, no work has been done on the bridge. From what I understand, there is division on what to do with the bridge. Some people want to replace [...]
- Short Warren Truss Popsic...
This popsicle stick bridge was made from 40, unmodified popsicle sticks. The bridge spanned 12 inches, was 4 inches tall and 3 inches wide. I used only Elmer’s white glue to build the bridge. It weighed 57.4 grams (0.13 pounds), and held 90 pounds. Its efficiency score was 712.
