Bridge Presentation By David Jackson & Matt Dean

Our team members are David Jackson and Matt Dean we tried our hardest to make a truss style bridge. The stress testing was difficult. I hope that you enjoy seeing our presentation.

Technical Detail/Drawing The Truss style toothpick Bridge

Design Challenges/Successes Design Challenges It was hard to create a frame for the bridge Completing the bridge on time was difficult. There were a lot of distractions keeping us from completing the project. Trying to keep the lines on the drawing straight so that we could fit the tooth pick in. It took a long time for the glue to dry so we could only work on one part of the bridge at a time. It was hard putting all parts of the frame together. Design Successes We were able to finish the bridge on time. Our bridge was able to hold 2714 grams so that shows our bridge could hold a lot of weight. Our bridge looked nice. Our bridge was able to be within the weight limit and our grade did not go down because it was over. There was great team work all around. AND WE HARD PLENTY OF TOOTHPICKS!

Suggestions for Improvement We could have used more time to work on the bridge it self so we could get it in on time. Next time we should think about more design styles because it seems the truss was used a lot in the project. Next time we will also start or technical presentation earlier. Try not to play around too much!

Math and Science concept Sir Isaac Newton Newton's second force has to do a lot with the bridge because once we started putting the weights on the bridge the force of the weights would pull the bridge down and this was called tension. We tried to use a lot of triangles on the bridge because the triangle is the strongest shape. Math played a large role in the construction of the bridge because the bridge has to be symmetrical on both sides, the grams on the bridge had to be just right so the bridge would not weigh too much, also we had to calculate how many grams the weight was all together and then we added up the total to see how much it was in all. The End!
