Bridge Project
ENGS 33 - Solid Mechanics
For this project, I worked in a team of three to design, construct, analyze, and test a scale model of a bridge that is lightweight, strong, stiff, and aesthetically pleasing. The criteria of the bridge included evaluation of ratios and accuracy of predictions. This criteria included: ratio of the maximum load to the bridge weight, ratio of the deflection at a load of 1kN to the bridge weight, accuracy of prediction of the maximum load, accuracy of prediction of the deflection at a load of 1kN, and both creativity and aesthetics of design.
SKILLS DEVELOPED
- Design Specifications: met parameters of testing scenario, used specified materials (e.g. plywood ⅛” thick and ¼” thick, wood glue)
- Project Management: Met deadlines of different phases
- Preliminary Design
- Design Variations and Material Testing
- Analytical Results
- Construction and Testing
- Reporting
- Stress and Strain Analysis: Hand Calculations, SolidWorks
- Tensile Testing: Using Instron machinery
- Analyzed: Hooke's Law, Modulus of Elasticity, Yield Strength, Offset Method, Strain, Ultimate Tensile Strength
REFLECTION
This project helped solidify my understanding of the theory behind solid mechanics and strengthened my experience with SolidWorks. My favorite part of the overall process was the preliminary design phase; I enjoyed developing innovative bridge designs and fusing my visionary side with my practical side.
