Know Brainers Popsicle Stick Bridge Challenge
This newly launched YouTube channel, Know Brainers, put out their first video today.
Examples
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 in order to prove his hypothesis, and so built a third (as seen in the photo) to show his classmates what they’d looked like. He … Read more
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 have to work on the mathematics of the bridge. I wanted to stress the strength of the truss design, so within the rules, I made it … Read more
Verrazano Narrows Bridge
I decided, for the 50th birthday of the Verrazano Bridge, to put together a model. I always loved the bridge; I lived in its shadow in Brooklyn for years and now live on Staten Island, so I use it often. Being a 2 year dad, I get little time to work on it, and when … Read more
25″ Arched Warren Popsicle Stick Bridge
Re-engineered for 2014. This update to a classic design brings more realism, but with a cost. Find out more below.
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 I had to calculate each ones length, and the approximate measure of the angle I had to cut into each one. All in all, the … Read more
Masterpiece Popsicle Stick Bridge
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…
100 Stick Popsicle Bridge: 21″ Howe Truss
The 100 stick popsicle bridge challenge is on. This Howe Truss bridge uses 99 popsicle sticks, spans 21 inches, and holds 200+ pounds. It’s efficiency score is 678. This is an updated version of my old “Popsicle Bridge #3” which was the same length, but slightly different in construction.
ASL Bridges Class, Feb, 2012
The Arizona Science Lab presents information on types of beams used for building bridges. They show the huge difference in resistance to bending between a flat beam and an I Beam. Then different types of truss designs are shown and explained. Afterwards the students are given supplies to build their own bridges, and this video … Read more
Murrah High School’s Contest-winning Bridge
Hello! As promised, here are some pics of our bridge we entered into Jackson State Univ’s Mathematics & Engineering Fair (Jackson, MS). We were amongst what appeared to be a lot of other folks that were just as clueless as us about bridge building! This is our first effort, so a win is a win, … Read more
