Building Bridges, Part 2 (a study in vectors and forces)

Today you need to build a type of truss bridge with a deck elevation of 20 meters. The group must maximize the effectiveness of the bridge while minimizing costs. You must create a new bridge, not simply rework an existing design.

Points

Less than 260000 dollars (+5)
Tension forces less than 3000 kN (+10)

Print the Test Results report and the Bridge design and hand in.

Based on this data, you will build (tomorrow) a bridge of toothpicks, straws, gumdrops, and manila folders (concrete). You must provide a scaled drawing of your bridge (1 m = 1 cm) BEFORE starting this project.
