Beam bridges are the most common type of bridges, and include truss bridges. truss bridges distribute forces differently than other beam bridges and are often used for heavy car and railroad traffic. in a truss bridge, the beams are substituted by simple trusses, or triangular units, that use fewer materials and are simple to build.. Build a truss bridge that spans at least 25 cm using only straws and tape. once their bridge is complete, participants will place pennies or metal washers at the center of the bridge�s span to measure how much weight it can support. distribute supplies to each team: 20 straws and tape. give the teams time to plan and build their bridge..
Ultimate bridge builder kit - straw bridge schematic - page 2 6 bridge trusses. make 2 trusses, using the 10 vertical supports from step 5, 8 of the diagonal supports from step 6, and 2 new, uncut straws.cut one of the new straws to a length of 18 cm, and lay five of the vertical supports below the straw, using the white placeholders in part a, below, to space them evenly.. Straws; their task was simple: build a bridge that was strong enough to hold a plastic cup filled with 100 pennies. they could cut the straws to any length but their bridges had to sit at least one inch off the table. some teams succeeded and some failed but, either way, it was impressive to watch their problem solving and teamwork.. This is an interesting problem. thank you for the a2a. i challenged myself to build a simple bridge with nothing but tape and straws. i've had a great deal of fun thinking about it..
