Some of them are the Pratt truss, the Smith truss, the Howe bridge, and the Warren truss, etc. What I have chosen to make was the Howe’s truss bridge design. It has a very simple design and is the complete opposite of the Pratt truss bridge design. There were obvious weaknesses in the bridge that was built when it was tested with the weights. One of those problems was the joints. Not all of them were cut approximately. The gussets took the role to keep those pieces in place. I saw that there were some weak membranes that came out after being tested due to the fact that they were not cut approximately. There were very weak laminations done. I felt like it was too broad and thin that is why it broke away with less force applied. I decided to build the Howe’s truss bridge because of its simplicity and that it was easy to make. The uniqueness of this type of truss bridge is the diagonal membranes are inclined to the center
