Truss Design
Define a Problem
During this project, we wanted to work together efficiently, focus on correctly solving the truss, and use our time wisely.
Generate Concepts
The breaking point on the triangular truss wasn't anything suprising. The overall results of our first truss were very good. The maximum force applied to actually break the truss was 6.01 newtons applied at the right angle.
Our second truss broke in multiple places which was not expected. It also broke under a maximum force of 2.9 newtons which was not very good.
Static Determinacy is used to determine if the truss is able to be solved, or meets the equilibrium. To find the Static Determinacy you use the formula, 2J=M+R. The J stands for the number of joints in the cell, M is the number of members, and r is the number of reactant forces.
Develop a Solution
Construct and Test Prototype
Evaluate Solution
The first truss was the best because it took a larger breaking force. This means our first truss was stronger and worked more efficiently. Also triangular trusses are always the strongest and sustain the most force applied because of their shape and ability.
Present Solution
Conclusion
Our first truss held as good as we expected if not better. If we could change anything about it I would put more glue on the joints. The truss broke at the two points under compression, which was expected. The result of our second truss was not so good. It broke in multiple places, it was hard to say which one was under the most stress because so many parts were broken. We only expected one and also with a very little force applied. If I could redesign this truss, would apply the force at a different angle and have member DB going a different way.
