Roles
Even though in your group you have one or two role, you still have to do each role when working by yourself on your bridge. My role is the designer, and I was in charge of researching and modifying the design slightly to benefit us, as well as become an expert on the original design. I was also the fabrication manager when I was fabricating the bridge. I was the quality assurance manager when I inspected each part of the bridge to make sure it was glued properly and even. I was the project manager since I was the leader and was in charge of my section of the bridge, also known as the project. I was also the communication manager since I communicated using this prezi and to the teacher and other members of my group. I also recorded a daily log to explain the processes I completed each day.
What I Learned?
During the course of this project I learned many things about engineering, design and fabrication. The most important thing I learned is you have to be very precise. When your adding the tie members, if your stringers as well as the trusses don't line up, it's very hard to glue them in-place because you'll need to bend them to get them in the right place. When you bend the tie members, they will most likely snap due to the stress of the weight put on the bridge, ruining the stuctural stability.
The Most Challenging Part?
To me, the most challenging part in the bridge design and fabrication was adding the tie member. I found that they were hard to place because there wasn't a lot of space, and they wouldn't stay in place. I didn't have big enough clips to clamp the tie members in place so I had to hold them for a long time. I had to break apart the tie members from the stringers a couple of times because they were not straight. I overcame that by placing the tie members without glue, then putting pencil marks to show where to put them.
Relation To The Design Process
They relate because you need to define your goal which is to create a bridge strong enough to hold up a certain amount of weight. You then need to investigate what ideas or ways to fix it, then choose the best solution, which is what kind of bridge you want to make. Then you need to design your bridge to handle the different factors which is making it be able to connect to other bridges and hold up a certain amount of force. Then you need to construct it, which is obviously when you create the bridge.

DAY
‘DESIGN PROCESS’ STEP
& ‘ROLE’ YOU PLAYED
DESCRIBE WORK COMPLETED TODAY
1





Design Process Step: Create design and a dummy using popsicle sticks.
I created a slightly modified version of the original truss design to use as our bridge design.
We got 5 popsicle sticks and were tasked with making a perfect dummy.



Role: Designer


2





Design Process Step: Create a good copy of dummy and start bottom and top strainers.
Sand then hand in our dummy to be marked
Get 45 popsicle sticks and write your name on all of them
Start building stringers



Role: Designer


3





Design Process Step: Use the 45 popsicle sticks to create 3 top and 3 bottom stringers.
Used the 45 popsicle sticks to glue together 3 top stringers and 3 bottom stringers
I managed to make 3 top stringers and 1 bottom stringer
I clipped all of the top stringers together to sand them evenly



Role: Designer


4





Design Process Step: Finish the stringers and get them marked.
I sanded the stringers with sand paper attached to a block of wood
Got the stringers marked



Role: Designer


5





Design Process Step: Use the stringers to create 3 different trusses.
Got a laminated paper with the design outline for making a truss
I used the stringers to create one of the three trusses



Role: Designer


6





Design Process Step: Finish the truss and get them marked.
I created the last two trusses and checked for any inconsistencies
I put two binder clips on the bottom of each truss to let it stand so it can dry easier
I got my trusses marked after they dried
I got my tie members to hold each truss together



Role: Designer


7





Design Process Step: Sand the truss and add the tie members
I decided to double up my truss
I sanded all of the trusses with the sand paper
Figured out how to use the tie members



Role: Designer


8





Design Process Step: Add the tie members and glue them onto each truss.
After I did a little more sanding, I put a small amount of glue in each tie member and glued 3 on the top stringers and 3 on the bottom stringers
I later removed the tie members to make it easier to transport home and finish it there
