Objective:

Using the fewest number of index cards possible, build a bridge that can sustain a minimum load of two 1/2-bricks. Materials to be used include 3x5 index cards, a maximum of one box of paper clips, a maximum of one roll of tape, and safety scissors. All materials will be provided. Dimensions of the bridge should be:

• • 10" minimum span length
• • 3" minimum width for decking
• • 12" minimum total length

Rules:

1. Bridge must be built on-site, but no time limit will exist.
2. There is no limit on the number of cards used, however, heavy penalties are levied for using more than 10 cards.
3. Loading will be done 1/2-brick at a time and will be placed at the center of span(s).
4. Maximum of three people per team, for safety.
5. Supports are to be excluded from the design.

Judging:

The judging will begin at 11:00 a.m. and once all of the completed bridges are tested, the winners will be announced.

• • Twenty (20) points are given for each of the quarter-bricks that the bridge supports.
• • Five (5) points are given for each of the remaining cards that the designer does not use.
• • Ten (10) points are deducted for each additional card that the designer uses. The designer who earns the most points wins. In case of a tie, bridges will be loaded until failure.

Prizes:

First place, Second place, and Third place. You do not need to be present to win.
