A2- Bell

For my A2 bridge design, I chose to go with a more simplistic design. There are only 8 diagonal members in the whole design (excluding the 2 on the very end). What is unclear and hard to interpret is that the diagonal trusses on the inside are alternating orientation from front to back. In other words, the middle diagonal members coming out of the 135 degree pieces form a "W" on one side (either on the close side or far side). The opposite side would be every other truss. Overall, I learned from designing this bridge that it is harder that I thought to make the bridge geometrically sound. Lots of members needed to be changed. The first time around, I found myself trying to fit different members in different places because my specific shape didn't allow what I initially wanted.
