Bridge+Project

**NAME: Simran Saini and Demi Chavez CLASS: 4th period**
 * BRIDGE PROJECT**


 * INVESTIGATE/PLAN

1.** What are the design specifications? (Write the assignment requirements here)
 * 1) **Your bridge should cross over an index card**
 * 2) **Your bridge should be 5 - 6 inches high**
 * 3) **Your bridge should 4 - 5 inches wide**
 * 4) **Your bridge should hold at least 100 pounds**
 * 5) **You get one handful of popsicle sticks**

below: (List at least three) http://science.howstuffworks.com/bridge4.htm** that cross it. It spreads the weight evenly throughout the whole truss. The members each have the same weight that way the truss doesn't break. it creates a very rigid structure as well as evening out the load among the members.
 * 2.** List the information you gathered and where you gathered it from
 * __Information Where__
 * A truss has the ability to even out the load of the cars and such
 * The different members each experience compression and torsion.
 * Trusses are made of a bunch of different triangles, because of this


 * 3.** Describe/draw at least three brainstorming ideas for you bridge:

We drew it on another piece of paper and turned it in.

We are going to use solution #3.
 * 4.** Which solution are you going to use? (Choose from #3)

5. List at least one success with your bridge:
 * CREATE**

6. List at least one troubleshooting problem with your bridge:

7. Did your solution solve the problem?
 * EVALUATE**

8. What worked well with your design?

9. What did not work well with your design?

10. What would you do differently next time?
