E3 FAIR SURVEY RESULTS:

Seven Model bridges were shown at the ABCD table during the E3 Fair. Students and adults were asked which of the seven would hold the most weight and which had the best efficiency ratio (load carried divided by the weight of the bridge).
MODEL BRIDGES IN THE SURVEY
These Bridges were designed and built by practicing bridge engineers.
Thank you engineers for your contributions.
