We choose this design to understand the structural integrity of a suspension bridge. The bridges span is slightly larger than 30cm. It is made from sate sticks that are joined with a rubber band to represent a pin joint. Nylon was used to represent the cables in a suspension bridge.When the load was applied onto the bridge, The sate sticks in the middle began to fold inwards. The nylon was in tension, but wasn't strong enough to prevent the bridge from folding inwards.This structure taught me the advantage of using pinjoints is that the structure rather than breaking, folds inwards.
