You have a challenge. You are to construct a 2D truss bridge model which can hold the maximum weight at the centre with the smallest bridge mass. You have to follow the following conditions:
Minimum length of 500 millimetres
Maximum height of 90 millimetres
Maximum weight of 50 grams
You can only build out of the following materials:
Timber which has a mass of 5.5 grams per 300 millimetres
Glue with weight of 1.5 grams per 200 millimetres
How would you make the bridge?
