Week 6

This week, we have drawn sketches of the truss designs and we have been prototyping ton figure out which truss design we are going to use. Blake is going to draw and build the Warren truss design.

Katie is going to draw and build the Baltimore truss design.

Sierra is going to draw and create the Pratt truss design.

We will use these prototypes to figure out of which one is the best choice.

Week 5

This week we started to move our data into graphs. We put the data into charts so it is easier to compare. The following charts are the ones we created today and we will then take that data and analyze it to help make the type of truss we want to use. The following pictures are the types of trusses we tested. The trusses are the side part of the bridge that helps support the bridge.

Week 4

This week we worked on getting the truss design down for our bridge by using the Model Smart software on the computers in Mr. Spiece's room. Model smart is a software that is used to test different truss designs on the computer and it will tell you the strength and weight for each truss design. This is the first official week of testing trusses. We also started working on sketches for the actual bridge design as well. Lastly, we updated our blog. :)

Week 3

This week our team found out what type of bridge we will be building. For this years competition we will be building a cantilever through truss bridge. The picture to the right is what the bridge should look like on paper. This week we started research and our proposal. Also TRAC (the company who puts on the competition) put out the guidelines for this years competition and we looked over them.
