week 4

Since we have been experimenting with West Point Bridge designer, we have noticed many helpful options.  Some ways to make the strongest and most cost effective bridge would be to use hollow tubes and to change each of their size.  These variables now restrict us less and allow us to be more creative in our designs.  I also enjoy the fact that this program also allows us to pick each weak member and make appropriate modifications to it.  There are some drawbacks.  For example, this program shows a truck moving across so the force is felt in different areas of the design.  This conflicts with future designs for our Kinex design will have a fixed load in the middle.
