K'nex Bridge Competition
--------------------------------

In the competition in class our bridge placed 2nd out of five teams. Overall there were four bridges that could hold the required weight and out of those four, two teams were penalized for not adhering to the requirements. The winning team's bridge held the required weight and had the least amount of building costs. Our bridge had the second least building cost with a price of approximately $50,000. In conclusion, the bridge we built was a good strong bridge that was able to hold a little bit more than 20 lbs. We could have probably found ways to take away a couple knex pieces around the entire bridge to reduce cost but we decided to stick with a bridge that could hold a little bit more. As you can see below in figure 1, the bridge was structurally sound and able to hold 20 lbs.
