Basswood model bridge example (built by Mr. Carlton) for students competing in the MSPE competition at MSU April 4th.
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, right? It is made entirely of 1/8″ square balsa. It weighed 0.1 lbs (~45 g) & supported just under 10 lbs. The top chord is […]
I just found some old pics of my first ever Science Olympiad bridge. These photos are 7 years old. Many props to my mom for keeping them. 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 College. The bridge placed 2nd. Richards MS placed first. Man, these pictures sure […]
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!
This bridge won the 2004 GA State Science Olympiad Bridge Building competition. It weighed 9.47 grams, spanned 35cm, and held 15kg without breaking. The efficiency score was 1584. This bridge was made completely from Basswood. No Balsa or other wood was used. The top chord was made from 2 sticks of 1/16″ square pieces, laminated to a 1/32″ x 3/16″ piece. I steamed the wood for the top chord before bending or gluing. Learn more about bending wood. Theory This […]
