Last week in class we start work on out 36”inch bridge. The 36”inch bridge has a different rule than then the first one. The 24” inch bridge only have rule on lengths, but the 36” Inch Bridge have limited on high of the bridge. The span of the bridge is also increasing a big amount. That made the second bridge has a lot of different part than the first one. By using the force calculation we find out that the 36” bridge could not be simple as make it longer. It needs a lot of change. We are trying to work the best way thought to make a better bridge. This week in class we are start to text our 36”bridge. The 36” bridge would be a more advance bridge. We have learned a lot of different thing in the class. We also get data from our test information. I am really exciting to see how does our bridge do in the finial competition. I believe this time our bridge would improve.

    This term engineering class I really learn a lot. First I get know different type of the bridge, Especially the truss bridge. We get know about truss bridge, and use it in all our bridge. The first bridge is doing on the west point bridge design. The west point bridge design give an ideally bridge. On the west point bridge design we could test bridge and see the weight that is do on each member. That is very helpful for future design. After the west point bridge design we start our k’net bridge and learn how to calculate the force on each member. How to make a good serviceable bridge in a low cost is our finial goal. In the class we use a lot of thing we use in physic and really life to made the best bridge we can possible make.
