Albury High School Popsicle Bridge record breaker!
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!
Bridge Terms
Hey everybody once again it’s me, First Timer. I thought the one thing that would make this website even better would be some vocabulary on the parts of bridges. Here are a few terms that might help if you ever need to describe different aspects of a truss or bridge. Let’s start with “Arch”…
Classic ‘K-Truss’ Bridge Design (Balsa Wood)
For this balsa wood bridge, I used a ‘K-Truss’ design with seven vertical members and 6 ‘K-Trusses’ per side. The K’s were the most challenging part of the build, because…
Coolest Popsicle Bridge
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.
Dombiggers 1st bridge
A very nice looking Balsa wood bridge sent in from one of my readers. This bridge uses gussets and pin joints and spans 18 inches.
Drew’s Science Project
Drew’s science fair was this past Friday, and he won a special award/ribbon for a “Superior” project. I’ve attached photos of he with his tri-fold board. He built/destroyed two bridges…
First attempt at a DIY model bridge
It’s taken me just under 48 hours to get this far. Although i wouldn’t say its completely finished.. it’s a good as. I might just polish it off with a lick of paint and other aesthetically pleasing type things. As you can see, I’ve modeled it on the Pratt Truss. Although, I didn’t do any “real” plans, just rough drawings
First Timer’s First Bridge Design
Hello everybody my name is First Timer and I had to make a balsa wood bridge with theses specs: 40.5 cm long, 11-12 cm wide 13-25 cm high, must have a span of 26 cm, peek of the span must be at least 9 cm, and this bridge could weigh no more than 16 grams
First Timer’s Second Bridge Design!
Hey guys it’s me again, First Timer. Taking the critiques you guys gave, I rebuilt the bridge. This was going to a county Science Fair which I think is pretty cool considering I started learning about bridges about 2 months ago. The specs of the bridge are
Hell Gate Bridge 1/4 Scale
This post features one of the most intricate reader submitted bridges I have ever received. This is a model of the Hell Gate Bridge built by High Iron Models. Excellent work.
High School Bridge Building
We started our bridge program last year in my beginning engineering and manufacturing classes. I wanted to make a bridge that was very complicated with simple rules that required them to…
Hyun Seok Yoon’s First Bridge for the Science Olympiad
Hi this is Hyun Seok Yoon. As the title says, I just made my first bridge for Science Olympiad! Although it took me 12 hours (whew..!) I could see the good result! It held 15kg!
Ice Cream Stick Tower
Here is an ice cream stick structure made up from 200 sticks, which carried 30kg. of weight. Submitted by Sandip Babar. Questions from Garrett What glue did you use to…
K-NEX Bridge for Fun!
Hey guys it’s me again, First Timer. I came up with a good way to practice bridge building either before or for the next competition and/or just to keep your bridge building skills good, whether it be science fair or science olympiad. It’s building different bridge designs with K-NEX, Erector Sets, and/or LEGOs. Most of you probably own one or more of the following and it really helps practicing basic truss design
K-Truss bridge for Wake Tech engineering class
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
