As this was very much a project with many constraints, one of the main ones being the limitation of material. I decided to provide a list of the amount of material which we used, these are:
Double sided foam board with additional 0.1mm paper layer (recycled):
This was the main material which we used, 400mm x 100mm (x4) 800mm x 100mm (x4) 50mm x 130mm (x2)
Thread:
We actually ended up using all 4 meters of thread
Double sided tape:
100mm x 30mm (x8)
A4 printing paper:
We didn't use any of the paper.
Cardboard:
100mm x 30mm (x8)
So thinking about it now we did use majority of the material but as a team we felt that was necessary and in the end we were happy with the load our model was able to take. As this was very much an exercise trying to determine how much weight each bridge can hold, we had to work out a ratio from the materials used and how much weight that bridge can hold. So stay tuned for the ratios of each team.
