About this project: |
For the bridge design project a group member and I were required to design a model bridge out of wood and glue. We were tested on the efficiency of the bridge to see which group had the best design. (Efficiency = weight of bridge / weight held). For this project we put as much weight on the bridge until the breaking point. We were only able to use (8) 16 in. pieces of wood with the width of 3/32 in.

Take -a-ways:

For this project we had learned how to communicate with other teachers for helpful information and help, to buy more materials, and use CAD to test your bridge virtually. My partner and I worked well together for this project, and had done much research and planning for this project. We were proud of how our bridge turned out. Even though we placed 4th we still were happy with the amount of time we took to generate concepts. Many projects neither my partner or I had done that, and to finally complete that step of the design process showed us the importance of truly thinking your design through before actually building it. My biggest take-a-way was even without getting the best grade or getting 1st you can still feel accomplished in what you were about to figure put to further your knowledge of processing.

To the right is a slideshow of the different images we took of the bridge through the building process. We included a picture with dimensions of the wood cut, the glue used, and the weight of our bridge on a scale.

To the right is a slideshow of images for this project. My partner and I chose to test the beam deflection by putting our bridge into a CAD program, and virtually tested it. Some of the programs pictures show our real life bridges dimensions.
