Our first decision as a group was to decide the shaping that the bridge
would take and we collectively decided to have the bridge in a
zigzag shape as this differed from the bridges of the other groups designs. We then made the bridge by taping
full pieces of the cardboard together. Our next task was to decide where two place the two areas where the
bamboo could touch the ground and we decided that the best way to do this was to divide the length of the bridge into quarters. To do this we made two boxes to push the sticks
through so they could stand on their own with the aid of tape. After these
two elements were made we combined the two elements to see
how they would fit together and if the bridge itself would reach across the
space.
After seeing the logistics of the bridge across the gap we saw that the zigzag could not bend enough to gain the height for the table to fit under it. We then, as a group, chose to change the shaping of the
bridge to a simple straight line and decided to add
embellishments later. While half of us constructed the bridge the
other half worked on constructing the supporting
under elements of the bridge by adding layers of tape to
strengthen all of them and also added tension by adding elastic
bands horizontally across the supporting structure.
We then laid the new bridge across the supports and
connected them by taping pieces of cardboard to both the bamboo and the underside of the cardboard. This made the bridge sturdy after the points of elevation but weak on the
flat surface in the middle. To fix this we stuck two pieces of
bamboo in a X formation on the underside of this area. We also
constructed a 3D cardboard triangle to place under the
centre of the bridge between the cardboard and the X of
bamboo.
After we had finished the basic design of the bridge we began to
make barriers for the sides all away along the bridge so as to stop the car from falling off the
sides. We also added an archway at the beginning of the fridge to
give it a race course feel.
