Transcript of The World's Longest, Lightest and Strongest Popsicle Stick Bridge

The World's Longest Lightest Strongest Popsicle Stick Bridge By: Jay - Fabrication Manager Peter - Fabricator Nafiz - Quality Assurance Manager Essam - Communicator Design Process Input Materials Popsicle Sticks
Carpenter's Glue
Binder Clips
Pen
Jig
Screwdriver
Filer
Tie Members Process Goal To build the longest, lightest and strongest popsicle stick bridge that will be capable of supporting 150 pounds. Investigate, Analyze, Understand Using triangles will make the bridge strong because triangles are the strongest shape. This is because triangles distribute the load evenly. Possible Solution We could build a truss bridge. A truss bridge is a bridge supported by trusses which are structures consisting of beams in a series of triangular sections. Plan and Design Steps 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Make 3 bottom stringers consisting of 7 popsicle sticks each. Use binder clips to let the glue adhere. Make 3 top stringers consisting of 5 popsicle sticks each. Use binder clips to let the glue adhere. Write your name on the stringers using a pen. Using a screw driver, secure one bottom and one top stringer to the jig. Attach diagonals to make a perimeter. Use binder clips to let the glue adhere. Repeat steps 4 and 5 for the remaining stringers. Add diagonals in between for support for each perimeter. Use binder clips to let the glue adhere. Double truss the perimeters. Use binder clips to let the glue adhere. File the top and bottom of each truss to make the truss smooth and balanced. Connect the three trusses using 3 tie members on the top and 3 tie members on the bottom. 11. Attach 2 diagonals to each corresponding top and bottom tie members. Use binder clips to let the glue adhere. Construction The construction of the truss bridge took a period of 10 days. The bridge was built by following the plan and design. Day 1 and Day 2: Day 3: Day 4: Day 5 and Day 6: Day 7: Day 10: Three top stringers were built. Three bottom stringers were built. Three perimeters were built. Three trusses were built. The diagonals of the trusses were doubled. The top and bottom of the three trusses were filed All tie members were attached. Diagonals were added to the tie members for support.

Popsicle Stick Bridge
Prezi My Role My role in this group is the communicator. I'm responsible for making a prezi about our bridge and I'm responsible for fabricating my own bridge. Evaluation Our bridge was successful because it was able to support a person who weighed 150 pounds. The only problem that our bridge had was that it was slightly crooked. Everyone in this group did their part of the project. Next time, I would use better popsicle sticks and I would encourage others to work more efficiently.
