A-3 Question 5 McSorley

We found that the bottom deck truss was what was causing many of the problems we were having with the online Bridge Designer. Because of this, we decided to modify our actual bridge design to make an online design that would work. We kept getting an error telling us that the members plus three needed to equal to twice the nodes, causing the design to be "statically indeterminate". Our new online design is:

As you can see we had to remove the deck truss, but I think if we had the deck truss in this design, it would decrease the tension in the middle nodes and move it to the outside nodes.
