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.
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…
Highlighted balsa wood bridge videos from youtube.com. More videos to come.
I like this video because it is very systematic and well documented. The video shows a Balsa wood bridge built for a statics project. The bridge ended up with an efficiency score of 514.
This video has some excellent toothpick bridges. These bridges hold an incredible amount of weight before they break. You get to see it all on video
Video of a large Pratt truss bridge being loaded to failure
Here is a video playlist I created from youtube of selected popsicle bridge movies. You can see a variety of testing methods used in these videos. You can also see…
This is a video I found on YouTube of an excellent bridge built for the Troitsky Bridge Building Competition. The only materials allowed for this competition are popsicle sticks, toothpicks, dental floss, and white glue. This is a very impressive bridge. It weighed 1.17kg and held 805kg. That gives it an efficiency score of 688
This is a fun video showing the failure of a lot of Science Olympiad Elevated Bridges at the Crystal Lake Invitational 2009. Does anyone know what state this is held in? This video shows a lot of different bridge styles for Science Olympiad, so it might help give you a starting place for a design. Keep in mind that this is just at the invitational competition level
This is the absolute best video I have seen about building model bridges. Roy Coleman, the founder of the International Bridge Building Contest, gives a very informative presentation in this video. The presentation is over an hour long. He shows how to build a bridge from scratch. He is gearing his video towards the…
