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
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
This was one of my earlier bridges. I built it after talking with my uncle, who is a mechanical engineer. He suggested that I try using an I-beam. This was a very good idea, but my construction skills at the time were not the best. In theory an I-beam is excellent for bridges, but I … Read more
Boy does this bridge bring back memories. I built this bridge in 2001, in the 7th grade. It was my first attempt at building a bridge on my own after building this bridge with my partner. I had wanted to make an arch bridge, much like the Booth Bridge, but I didn’t have the building … Read more
I was never able to fully develop and use this bridge. I got this idea from talking with a Science Olympiad coach in Ohio. Now I wish I had gone ahead and put more work into this. The next year, the bridge rules changed so that I could not use this concept. The trick was … Read more
Chamblee has always done well in Bridge Building. In 2001, they won the State finals in this event. This bridge is from the 2003 GA State Tournament, the same tournament the Booth Bridge is from.
Yes, this is one of the coolest bridges I have ever seen. Built by J.C. Booth Middle for the Science Olympiad Georgia State Finals in 2003, it placed 3rd. For those of you who don’t know Booth, keep reading. Booth Middle School has won the Georgia State Finals as a team for longer than I … Read more
I just found some old photos of my first ever Science Olympiad bridge from 2000. 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 overbuilt. This was at my first every Science Olympiad competition at Gordon … Read more
This bridge was definitely not my best, but it does bring back memories. It was the second bridge built by my old Science Olympiad Bridge Building partner, David, and I. As you can see, we were still in the beginning of our bridge building career. I assume David is still building bridges, as his father … Read more
This balsa bridge was built by some students of mine for a Science Olympiad competition. It spanned 14 inches, weighed 8.1 grams, and held 29 pounds. That puts its efficiency at 1630.
