 1) Calculations

 2) Results on the Trusses:
        Truss AB has -131.87 N
        Truss AC has 88.24 N
        Truss BC has 131.87 N
        Truss BD has -176.48 N
        Truss CE has 88.24 N
        Truss DC has 131.87 N
        Truss DE has -31.87 N

4) The results I calculated are relatively close to the results from Online Bridge Designer. My values differ from the program with 3% due to inability to define specific lengths and angles on the Online Bridge Designer. 

5) The best advantage that software has is that is a lot faster in calculating the value although they may not be 100% correct.

6) Now that I know hot to use the Bridge Designer I can test a lot of designs in a short amount of time and also find the place where the designs may be weak and try to fix them. The program shows me that most of the force is being placed in the middle of the bridge and there is where it need improvements. I think by dividing the big triangles into smaller ones might help distributing the force better.
