Reflection on Bridge Building

  1. How much did your bridge hold?
  2. How much did it cost, and how did you minimize your costs?
  3. What is the mass of your bridge?
  4. Calculate the force weight of the bridge, and the force weight of the load applied.
  5. Using the member data sheet, which bridge member held the greatest load? How do you know?
  6. Can a member experience both compression and tension? Explain.
  7. IS your bridge model a good fit for the bridge you made in the program? Why or why not?
  8. Draw a force diagram for your bridge when the truck is on the left-hand side of the structure.
  9. How does friction matter in this project?
  10. What have you learned in this project about statics, force diagrams, angles, and vectors.

This entire sheet should be about 1 page long, hand-written or typed, and due on Tuesday.
