Video highlighting the top three bridges from the Maine Transportation Conference Popsicle Stick Bridge Contest. These bridges are quite impressive, with the winner holding 1278 pounds before breaking. The commentary on this video contains useful observations and thoughtful opinions from the video makers.
We run a comp here at Albury High in Australia for our Yr 12 Engineering Studies students involving max. 50 popsicle sticks, PVA wood glue and 2m of extra strong thread. Structures have to span 400mm and are centrally loaded. Here’s a photo of our 2010 winner which weighed in at 69 grams and held 58kgs giving an efficiency using the formula on your website if i used it correctly of around 12000!
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 newly launched YouTube channel, Know Brainers, put out their first video today.
This album highlights the Popsicle Stick Bridge that I entered into the Seattle ASCE Younger Member Forum’s Popsicle Stick Bridge Competition in 2009. This particular entry swept all first place prizes in every category: efficiency, aesthetics, and poster. It’s 30 inches long, 11 inches tall, 5 inches wide, weighs just under…
These are some pictures of a bridge I built mainly out of boredom, but also since I have an interest in engineering. It’s a large cantilever bridge, meaning it has two arms that extend beyond their piers that hold up a center suspended span. It’s 10′ 2″ long and as of right now is hanging across my bedroom ceiling
This is a very nicely built popsicle stick bridge. If you want to build a strong popsicle stick bridge, than I would suggest that try something like this. Because all the popsicle sticks are glue together, this bridge will have amazing lateral support. I used this idea on a lesser scale on my Prairie Popsicle Stick Bridge.
Here is a sneak peak at one of my newest creations: a model suspension bridge made from popsicle sticks and parachute cord. This bridge was created as part of a custom project I was contracted to design. While I had been thinking about building a kit/blueprints for a popsicle stick suspension bridge, I had not been able to create one simple enough to replicate easily. However, I found a way to construct one with a simple method and this is the result.
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 brace that failed. The truss ballooned out at the point when 2.2kN of force was applied. It was at this point that the test was stopped
