In this past week, the group started to work on our A3 assignment. In addition, the group started tossing around some ideas regarding the 36" bridge that will be constructed this week. We didn't actually construct anything, but got an idea. Our team has agreed that, in the coming week, we will begin constructing our 36" bridge. We plan to use a very similar design that we used for the 24" bridge. We figured that since this bridge worked quite well, it was worth a shot to see if it would span another foot, with some modifications of course. The major accomplishment that our team has achieved this week was having a basic concept on what we are going to be doing for our 36" bridge. Creating an idea could have been challenging, but our group seemed to do just fine. Our team faces no current issues at the moment. The only issue that I could think of would be having conflicting ideas about how the members and joints should be used/oriented; and the overall structure.
Basing my decision off of the Bridge Designer program, I believe that this method of analysis is indeed sufficient enough for a real bridge. Had we not had the numerical values of the tension/compression values of the members, I would say otherwise. Having the numbers handy enables you to visualize how close a member is to breaking (and how much weight it is taking). The one thing that I would like to know about the K'nex bridge is the value of the breaking point between the member and the joint. With the K'nex bridge, this point is the only problem that we are having. Having these numbers could enable us to further analyze our bridge and make thee appropriate adjustments.
