1.4 - Testing of Bridge

On Friday, we went to test the bridge at the Physics Lab:

This was the amount of weight we could hold (50 kg):


This was the final result of our bridge testing:


And with that, we calculated the structural efficiency, E, of the bridge:

E = Load supported in grams / Mass of bridge in grams

E = 50 000g / 435.37g

E = 115

Therefore our structural efficiency is 115.
