4. By comparing the "Bridge Designer" sketch with the hand-written results, one will notice that the results do not match up. The reason for this is because the "Bridge Designer" program does not work in units. Scaling both results will use the same units for each method of calculation, resulting in equal final answers.

6. Using this type of analysis is a great way to visualize the weight distribution of our bridge. After seeing on our bridge where exactly weight and tension are highest, we may choose to strengthen these areas by using more Knex pieces or slightly rearranging the joints to decrease the chance of the bridge breaking at that point. Also, some pieces seem to not be managing any weight or tension at all. We will most likely remove these pieces to cut down on the bridge's overall cost.
