1. The problem statement, all variables and given/known data In class we were asked to build a bridge with the length of 50 cm and the width of 20 cm, maximum weight is 50 g and the test is to place the bridge on two parallel chairs and then place a heavy object in the center. we can build any type of bridge. material: unknown. My question is that what would be the most efficient and easy to build bridge type that can cover all mentioned criteria? if you have any advice on bridge making please share, it would be a great help. Thank you 2. relevant equations the modulus equation? 3. attempt at solution I was thinking of building a cable stayed bridge as it seems to be the lightest as per theory.
