This term, 7 Tech 9 have been studying, designing and creating truss bridges. A truss bridge is a bridge whose load-bearing superstructure is composed of a truss – a structure of connected elements, usually forming triangular units.
The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads.
A stroll to Waverley Park one afternoon, allowed us to observe truss structures such as cranes and the telecommunications tower at Bondi Junction. Lessons in the woodwork rooms have seen some great collaboration, problem solving and challenges, as groups compete to create the strongest truss bridge.
Students are looking forward to testing their structures to see how much weight they can bear.
