In this project had to build two trusses out of balsa wood and super glue. We then found all the measurements of them and tested them to see how they would perform under a great amount of stress. Also where the truss would break due to the stress.
Truss W = weight of truss (g) W = Converted (N) F = force applied at failure (N) Efficiency calculation ( F/W )

Truss 2 Calculations
Conclusion Questions
1) The failure of the truss occurred at those spots because those were the spots where the stress was the greatest on the trusses, and yes these were the spots that i saw the most stress on in my calculations.
2) If i could have redesigned after testing, i would have found a way to make the failure location more structurally stable. This would allow the truss to undergo more stress/weight and maybe save it from being snapped in half.
