The requirements for the bridges you will build are listed below.
Also, read the Engineering Design Process and Manufacturing Process before starting.

Rules and Requirements
Students will build model bridges. The bridge that can hold the most weight wins.
Bridges have to be between 250mm and 300mm long and width must be between 50mm and 75mm wide.
The bridges must be less than 100mm high.
The only materials you will have are a knife, working surfaces, ruler, 15 pieces of balsa wood, and glue. The balsa wood pieces are 61 cm long and 4mm square.
You can NOT laminate the wood - in other words, you can NOT have pieces of wood glued together lengthwise to create a larger surface, like a board. See me if you have questions.
You will not have to build any legs or supports - that will be done with books.
Your design should be well thought out. You should have drawing of your design (3 views - side, top, front).
You should also create a template where you can lay the wood on the paper and then glue it.

We will start building the bridges after you have done your research and designed your bridge.
a) Read Engineering Design Process and Manufacturing Engineering -
b) Read the Bridge Project Rules - http://mrandradesphysics.blogspot.com/2012/02/bridge-project-rulesrequirements.html
c) Look at some other bridge designs and how they will be tested:
d) design your bridge using the knowledge you gained from the bridges webquest and following the rules and requirements.
e) have your design checked by me
f) build your bridge following the tips in the manufacturing reference
g) test the bridges
