4. From the pictures above you can see that my calculations and the Bridge Designer screen cap do not match up. This is because in Bridge Designer there are no units. To counter this the hand written calculations have to be scaled.

6. From using Bridge Designer you can really tell where all the tension and compression are. From the analysis from the link you can see that adding more K'nex to the joint, making smaller triangles, makes it harder to break the joint. We may add smaller triangles where the tension and compression are the greatest and maybe take K'nex out of joints that have small forces acting upon them.
