Competition Update

The competition took place on April 9th at the City College of New York. The team constructed the bridge with a total time of 10:19. The team incurred 3 15-second penalties; one for dropping a nut, one for dropping a tool and one for the support sliding out of the footing. Therefore the total competition construction time was 11:04. The bridge had a final weight of 235 lbs. The team also incurred a 100 lb penalty because the bolts extended 1/4 inch beyond the decking support surface. The bridge passed the lateral load test but ultimately failed during the vertical load test under a 2225-lb load. The collapse occurred due to shear in the bolts. The next step for the team is to perform a failure analysis.
