These are the pictures for the design of my bridge. For the bottom and top section of my bridge, I decided to stick to using right triangles as I believe they support the most stress out of all of the different kinds of triangles. I also try to use them in the middle section, but I found it hard to make it stable so I ended up using other kinds to make it symmetrical. I started off by following the Pratt design template and just worked my way from there.
The price for this bridge is roughly $453,775.37. I have no idea if that is a lot of money for a bridge of for this task, but I'm sure I can lower the cost by a significant amount after I figure out how a bridge works.
I learned that right triangles work better than equilateral and isosceles triangles. With that knowledge, I changed all of my other kinds of triangles to right triangles. I don't really under stand the physics yet, but that will probably be one of the things I'll look into. For the future, I plan on getting rid of those red support structures in my last picture and turn them gray.
