project explanation
in this project, we had to create two different trusses with balsa wood and super glue. We were given measurements in a packet that we received for the project. We had to make them accordingly and then find out the stress at breaking point and where the truss broke from.

Truss W = weight of truss (g) W = Converted (N) F = force applied at failure (N) Efficiency calculation ( F/W )
1 2.5g .025N 57.3 (N) 2292%
2 4.7g .046N 67.23 (N) 1461.52%
1 2.5g .025N 57.3 (N) 2292%
2 4.7g .046N 67.23 (N) 1461.52%
conclusion
- The failure of the trusses occurred at the place that they did because that was where the most force was acting upon it.
- I would go back and improve on the places that were the weakest points on the trusses.
