THE WORLD'S
LONGEST, STRONGEST, LIGHTEST
POPSICLE STICK BRIDGE

GOAL
FABRICATION PROCESS:
FABRICATION PROCESS:
FABRICATION PROCESS:
To create the world's longest, strongest, and lightest popsicle stick truss bridge, that will be able to successfully hold the load of a 150 pound person.
FABRICATION PROCESS:
Goal: Three trusses
Place, and line up a trapezoid on the blueprint
Get 8 strong popsicle sticks and glue them onto the trapezoid, according to the blueprint, keeping a 1/4" gap between the sticks
Press together and attach binder clips
Wipe off any excess glue
After dried, flip it over and repeat last three steps on the back
MATERIALS
MEMBERS
Yumna Sajid - Fabricating Manager
Kyle Samuels - Fabricator
Rufaida Rahman - Quality Control Manager
Samuel Parsad - Communicator
Goal: 3 top and 3 bottom stringers
Get many strong popsicle sticks
Place the dummy on one half of the stick
Cover the the remaining half with glue
Place another popsicle stick on the part covered in glue
After making sure it's lined up, press together with binder clips
Wipe off any excess glue
Goal: 3 trapezoids or perimeters
Place one top and bottom stringer on the jig
After making sure they are lined up, screw both in to place
Apply glue to either tip of a popsicle stick
Place it on one side of the jig, after making sure it's lined up nicely
Press firmly and attach binder clips
Repeat last three steps for the other side of the jig, to complete the trapezoid
Goal: Stable truss bridge attached with tie members
Hold and line up three trusses
Decide where tie members will go, three on top, three on the bottom
Drop a drip of glue in the three spaces on one member
Carefully place it and tie the three trusses together
Hold it there firmly for a minute
Wipe off excess glue
Repeat last four steps for the remaining 5 tie members, always making sure the black mark on each member is facing the same way

#2 TRAPEZOIDS
#3 TRUSSES
#4 TIE MEMBERS
FABRICATION PROCESS:
Goal: Three double-sided Xs in bridge to make it as strong as possible
Choose some nice, strong posicle sticks
Put a drip of glue on either tips of one of the sticks
Place one tip of that stick on the left side of a top tie member, and the other tip on the right side of the bottom member
Press firmly and clip on two binder clips
After spreading glue on the ends of another popsicle stick, press one end to the right side of the top member and the other end to the left side of the bottom member, resulting in an X
Attach binder clips
Repeat for the remaining tie members
Optional: Repeat the steps on flip-side of tie members to create double-sided Xs
#5 DIAGONALS
FABRICATION PROCESS:
#6 FILING/SANDPAPERING
Goal: A final straight, strong, smooth structure of a bridge
Choose a piece of new sandpaper and
a file
Use either tool to rub down any edge

DESIGN PROCESS
DESIGN PROCESS:
INPUT
Plenty of materials, resources, and information were given before and throughout this project, which really helped in accomplishing the goal. Included were a blueprint, various documents, a few videos, and previous assignments.
DESIGN PROCESS:
UNDERSTANDING
The blueprint was read, looked over, and understood. Key words like tension and compression were learned and understood. Tension is the state of pulling or stretching tight. Compression is the action of pushing down or compressing. Also, videos were watched to understand the different types of bridges: beam, arch, suspension, truss, etc.
DESIGN PROCESS:
SOLUTION
Throughout this project, many things didn't go as planned. For example when the bridge collapsed. That wasn't expected. It was decided that adding Xs made the bridge much, much stronger. Also the bottom of the bridge should be sanded very well, to make sure the bridge itself stand up straight not lopsided, which could result very badly.

DESIGN PROCESS:
EVALUATE
Creating the world's longest, strongest, and lightest popsicle stick truss bridge was a great success! It was able to hold the full weight of one of our members, without even cracking. But throughout the creation of this process, there were many downs. For example crooked stringers, different sized trusses, etc. Despite the negatives, this project was a lot of fun to do, and I was just glad to finish it!
VIDEO
Here is a video showing the testing of a popsicle stick truss bridge:
OUTPUT
DESIGN PROCESS
We ended the project with various documents like the daily log, this prezi, a lot of knowledge in the topic, and of course an excellent, long, strong, light popsicle stick truss bridge!
Series of steps that transfer the knowledge you already know into the real world.
THE END
THANKS FOR
WATCHING! :)
