1) My initial estimate for the weight mine and my groups bridge could maintain was 10 pounds. It actually held over 50 pounds. Why I believed at the time it would only hold 10 pounds was because the wood was very frail, not all the strings were fully tensioned, and I just believed the bridge was too fragile.
2) Where I believed our bridge would break was down the road deck. I believed this because I thought since the road was made of balsa wood and so fragile it would hardly be able to hold more than 15 pounds at most, my estimates were off.
3) Our bridge broke at 65 pounds, and it snapped in half at the road deck.
4) It snapped in half due to the weight pushing down on the middle of the bridge, keeping the middle of the bridge intact yet having both the right and left side of the bridge snap in half.
5) What I personally liked about my bridge was the design itself. Out of the suspension, cantilever, and cable-stayed bridge I prefer the design of the cable-stayed bridge, just a personal preference of mine.
6) What I disliked about the bridge was how weak it was. Although the material we used was cheaper and lighter I’d of much more enjoyed a bridge that was a bit heavier yet could handle a lot more weight.
7) What I personally thought would be hard for building my bridge was definitely the braiding of the cables and the tensioning of the bridge cables.
8) I believe my prediction was accurate on the matter of braiding the strings and tensioning the cables. That was extremely tedious and time consuming.
9) What I would do differently would be braiding the strings earlier to finish that task quicker.
10) I believe that even if we made those changes the bridge still would have collapsed the same way it did.

1) I thought my bridge would carry at least 20 pounds because the strings of my Cable Stay were un-tensioned and the total thickness of the bridge was 2/8 of an inch.
2) I thought my bridge would break down the center because the strings were un-tensioned and the weight would tear through the center of our thin road deck.
3) My bridge broke at 65 pounds or 29.4835 kilograms.
4) The glue holding the bottom of my deck together gave way and led to a catastrophic breakdown.
5) The glue in the area was unable to sustain 65 pounds of sand and other materials.
6) I like the braided rope of my bridge, it gave it a kind of professional look while the rest looked really... bad.
7) The amount of glue we used on our bridge was a bit much and it gave it an unprofessional look.
8) I thought tensing the strings would be the most difficult part of our bridges construction.
9) The hardest part about constructing my bridge was tensing the wires. As the wires continuously tore and broke our balsa planks.
10) I would have used a thicker road deck and remade the towers so tensing the strings would be easier.
11) With any luck the changes would have lead to the bridges destruction all at once.

1) I said that the bridge would hold eighteen kilograms because my group went first and we never learned how to do the truss analysis for cable stayed bridges and because we were the first bridge to go so we had no idea on how accurate our rough calculations were. I said eighteen kilograms because I thought that the sticks holding the two road decks together would break or deflect earlier than it did.
2) I thought that the road deck would break because I thought that the way it was built was weak and did not have any stiffness to it so I thought that it would be the first thing to go. The bridge broke at twenty-nine kilograms or sixty-five pounds. The bridge first failed because the road deck separated and lifted the ends of the road deck off of the blocks. After that the towers fell and the bridge was completely destroyed. This happened because the road deck was not strong and because there was not enough struts holding the two separate road decks together, and because the road deck was not thick enough.
3) I liked how the bridge had a unique look. I did not like how the road deck was so thin, how the cables attached to the towers, how the towers were separating the road deck. I also did not like how the towers had nothing making a base.
4) I thought that the most difficult part would be attaching the cables to the towers because I had no idea on how to do it with the way it was set up. The most difficult part of the build was attaching the cables to the towers.
5) For me I would have changed nearly everything because I did not like the design but because I was sick when it was designed I could not do anything. But if I could I would have had the road deck be solid instead of having two separate ones and had the towers be on the outside and not in the middle. I also would have had the road deck be two inches. I have no idea were the bridge would break if I did the changes because the changes are so different. I would think that either the string would break or what they are attached to.
