Bridge Contest 08

I won first place in the 9th annual bridge contest today at Cal High.

The bridge was .35 oz and held 25.5 lbs. The contest was based on strength-to-weight, not sheer strength, so they divided the weight the bridges could hold by the weight of the bridge. so mine was 25.5 / .35 = 72.857. (The strongest bridge held about 54 lbs.)

I now have a plaque, certificate, and a drafting desk, chair, and light.

I was really surprised to have won the contest, as Timothy's was only 3rd his year, with 30-some lbs. The contest used to be based only on the weight the bridges could hold, and I knew that mine couldn't hold very much since it was so light.


  1. Wow! congratulations on first place. I would love to hear more about it.

  2. Looks like you used a Pratt design for your trusses, which actually form a "W" for Way to go, Wilson!

  3. A good surprise. Nice prizes. Good work.

  4. I am very proud of you and your bridge building skills. Will be nice to see your prize, also where you were able to put it. You may have to rent out a special room somewhere. Ha!

  5. Impressive! My "inventive" triangular design bridge got me in a three-way tie for 22nd place in seventh grade. I would've been glad to offer my expertise since this was your first competition and all. Too bad you missed out.

    I blame the balsa wood manufacturers for my colossal failure as an engineer.

    Keep up the good work Big D! :)
