  1. Garrett, I was considering hosting a balsa wood bridge design contest at my work (a engineering firm specializing in long span bridges). I work in New York City and it’s not easy to transport anything too heavy (like weights to test the bridges with). I’m wondering if you know of any places to buy cheap S-beam load cells that have a USB plug? Using something like this, I could create a lever to apply a load on a bridge and plot the force on a computer (the max force before the bridge collapses will be the max force held). All the S-beam load cells I’ve found are well over $100, and for a ‘for fun’ contest, I’d like something much cheaper. I expect these bridges to hold no more than 300 pounds.

    • Nick, unfortunately I do not know of anywhere to get a cheap S-beam load cell.

      I have heard of a low tech idea that uses a car jack for testing bridges. The jack needs to be hydraulic and have the ability to be lowered down slowly. You also need a hanging scale capable of measuring up to the point of failure. You attach the hanging scale to the bridge with a block and chain. Then you raise the jack and attach it to the bottom of the scale. Slowly lower the jack and watch the scale until the bridge breaks. I heard of this idea from a person who used it for loads of under 50 pounds. I do not know how it would work for a 300 pound load.
