Day 5

Today is grand fianle of our bridge project. Now is the time that our Bridge Americna Dream fullfilled our promise.



 

 We measure our bridge strength my pouring sand in bucket. We keep on pouring a sand until the bridge break apart.

 

At end American dream fulfilled our promise of holding the weight of bucket and few gram of sand. From my observation, we notice that tension of each side of bridge was uneven. As more weight add in, tension of one side of bridge gradually increase and one of bars just rip apart.  



 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Day 4

Hey guys, sorry for late update, we will show you our progress we made so far.

We appolize that our project is behind for others but we mange to chatch up with everyone else.




Our group couldn’t finish on time, so I need to make up our project at my house. Using the reference from blueprint, we cut truss to certain size.



Let me introduce you guy my dog T-bone. He was attentively watching me work on my project. Good thing that he didn't interrupt me during my progress.

 
This is finished product of triangle.

Finally our bridge finished. Sorry that we couldn’t show our progress after the triangle, we completely forgot to take picture. We name our bridge American Dream, we hope our best that our bridge can fulfilled the name.

 

 

finally our Bridge is compleye. Sorrry that i coundn't show you guys

Day 3

Hey guys, sorry for the lack of updates, we had other business to attend to on Friday so we haven't continue truss building until today (well, technically yesterday).

Anyways, for the third day of the project, we began an assembly phase of everything.

First, we made sure we had all the necessary items for the bridge, and we found that we actually were lacking a few gussets. Because of this, we made a few more gussets to the project.

                                                                 Gussets

After doing so we proceeded to put together the project to make the truss itself. 

First we put the diagram we wanted on a foam board. We covered this in wrap before pinning it down with needles.

Upon assembling it like this, we measured out various pieces of equipment to it and trimmed any piece that was too long. After the trim, we then nailed down the gussets into the board and glued the bars onto it.

From there we repeated the process. We are coming close to finishing the truss. We only need to attach the tubes together for this diagram :)

Day 1 and 2

The project has begun!

In class we received blueprints and a Manila folder which we would be using as materials to construct the bridge.
   

For the first day we were to use our exacto knife to cut out strips of the folder in order to create bars for the truss bridge.Unfortunately due to my clumsiness my partner and I found ourselves able to make few bars on the first day.

To deal with this problem, I brought a straight edge cutter the second day and work progressed much quicker.

   


For the second day of class we managed to create several bars along with the beginnings of a tube to sustain the truss. Though our progress had been slow the first day, we have caught up this day and will likely move on to the actual setup by tomorrow. Wish me luck!

Day 1: The very beginning

Hey everyone!

This is a blog dedicated to my AP physics attempts to build a sustainable bridge. I will try to provide updates on the process everyday and I hope you enjoy this blog and my inevitable clumsy errors :)
