Tips:
Keep your design simple and use the principles learned using the Bridge Designer application.
More material does not mean better efficiency. For every gram your structure weighs it needs to hold 500 grams additional load in order to achieve the same target efficiency.
Don't be afraid to start a second iteration from scratch. Sometimes as you refine your design you can see a better way of making it. It is often easier to start from scratch than fix everything. DO NOT delete your old design though; this can be used to document your process.
Project Instructions
Overview:
Civil Engineers use structures to span gaps in a variety of locations: rivers, canyons, overpasses, and many more. Often the resources available to them are limited and the most critical design factor is efficiency. This means the structure must hold as much weight as possible while minimizing its own weight.
Problem Statement:
Working in 2-person teams design, build, and test a wooden structure to achieve an efficiency (η) greater than or equal to 500.
Efficiency (η) = Critical Load / Mass of Bridge
