| BRIDGE DESIGN - EMBELISHMENT |
| V. Ryan © 2012 |
| |
|
There are several different types of bridge, each designed in a particular
decade or century and for a particular purpose. Make a straw ‘girder’
bridge, then select a type of bridge such as stone arch, suspension, cable
stay or a box girder. Draw two copies on paper. The paper should fit the
sides of your straw model bridge. |
|
|
|
1. Using a scissors, cut two pieces of paper to size, so that they
accurately fit each side of the bridge you have made. |
|
|
 |
|
|
|
2. Draw the style of bridge you have selected on both pieces of paper, or
draw it once and then photocopy the original drawing. |

3. When accurately drawn and enhanced with colour / shade, stick each
piece of paper to either side of the bridge. |
|
|
 |
|
|
|
4. The bridge is for a strength / compression test with weights. Each side
of the bridge will need supporting, so that a side way collapse does not
take place, whilst the weights are added. Special supports hold the straw
bridge in position. |
