Option 3
Static determinacy describes a structure where force and moment equilibrium conditions can be utilized to calculate internal member actions. It affected our designs, because we had to think more deeply about how many joints and members were in each truss, then calculated them to see if they worked. Sometimes the members wouldn't create enough joints, so then a joint would need to be added or taken away.
The force that we believe our design would be capable of holding came from our initial test truss. It could probably resist 4 more newtons, 50 instead of 46.36.
DEVELOP A SOLUTION
CONSTRUCT AND TEST PROTOTYPE
EVALUATE SOLUTION
This chart shows the weight of each truss. The maximum forces are applied and so is the total efficiency. Efficiency is found by dividing the maximum force by the weight. The higher the number the efficiency is the better the truss. The model 3 truss was the best one to use because the efficiency was the highest.
PRESENT A SOLUTION
Our truss with gussets.
How our truss was being tested.
The truss after testing; the marked spot is where it had broke.
CONCLUSION
The truss had failed because of the one member that is marked, because it had collapsed under the most compression. This was the same member that the calculations said was most likely to break when we calculated it in MD Solids. If I were to recreate the truss, the only change I would make would be to make more triangles/members in the middle of the truss to make it even stronger.
