Suspension bridges use cables to do this, and truss bridges use triangles on the sides to let the entire bridge help support the weight. triangles redistribute force in a truss bridge. Design and build your model bridge by: mr. chung khchung@interact.ccsd.net . main materials: cut and glue the outer members of your bridge make sure to put wax paper down first! glue the vertical members . glue the diagonal members . make another truss the same as the first . here are the trusses ready to build your bridge .. The warren truss is tried and true, providing a bridge that’s easy to build, strong, and relatively lightweight. in 1850, squire whipple designed the first warren truss bridge in america. in this project, we’ll make a model warren truss bridge..
Truss type bridges have a truss on each side and a section in between the trusses called the bridge deck. deck beams that connect to the bottom cord of each truss support the bridge deck, where the test car drives over the bridge.. Cable tie truss bridges: students design and build truss bridges, then test the strength of the bridge by attaching a scale.be sure to check out made for steam, an amazing collection of hands-on projects for kids!. Beam, truss, arch, suspension: each type of bridge varies in design, distance, and their ability to negotiate the forces of tension and compression. depending on the purpose of the bridge, how much weight it will need to hold, and how far it will need to traverse, engineers can figure out which bridge is the right bridge..
