Jobs well done – interesting site and information!
We built a 1/8″ scale model bridge just like the bridges we build for production. We successfully loaded it with 345 pounds with the weight being distributed all the way across the middle. Do you know of a formula where we can figure out that weight capacity for our full scale bridge? We have contacted 3 different engineers in our area who don’t have access to such information.
Thank you for your time and any helpful resources. (I cannot make the Johns Hopkins nodes and members work….?)
