Step 3 - Rough Sketch
The first step in building your bridge is sketching out the design of your bridge. This is not a blueprint, but it is a sketch of what you think the bridge should look like when it is built.
A sketch is a quick drawing of what you think your final bridge will look like. It may not contain every beam and girder, but it will give someone an excellent idea of what you hope to build. You should make use of the knowledge that you have gathered from reviewing the different types of bridge construction and the ideas and physics behind their construction. You might want to make several sketches. Don't hesitate to make your sketches full size. Also, make sure you understand the rules and requirements before beginning work on your sketches. Before moving on to the next step, creating your blueprint, you will need to have your sketches reviewed by your teacher. |
