Bridge joints – garrett' bridges: resources , For our physics class, we are required to make a balsa wood bridge. it’s a competition, and the bridge with the highest efficiency get a 100 as a test grade and the grades decrease as efficiency decreases. we have requirements: we may only use 15 pieces of balsa wood (2ft in length, 1/8 inch in width), and 2/3oz of wood glue.. What bridge design holds weight? – garrett', I’m building a balsa bridge that needs to span 36″. it only needs to hold 25lbs centered. the criteria for winning is to hold 25lbs with the most efficiency. my initial thought was to make an arch super and sub structure that overlaps on the main chord, with warren or k webbing(can post a sketch if it helps)..
