The research about bridges
The experiments on bridge
Our teacher's guidance us to prepare eight general white papers.And brought three toy cars from home. In the school microcomputer room on we did text about the different shapes of bearing capacity of Bridges.
Test process
| Prepare eight general white papers and three toy cars. | Put paper in two fold the plank to bearing a toy car limpingly. | When placed second toy car,the paper bridge is collapsed. |
Test process
|
| When the paper crowded arched, it can carry three toy carsand still intact. |
To reach a conclusion
By bearing the weight of an experiment,we can draw a conclusion: if material quality is identical, the impact of the bridge on bearing size of bridge is enormous .The bearing ability of bridge is much bigger than that of flat bridge .That is also why great majority of bridge structure all designs like this.
What's kind of the bridge in your opinion ?
Through all ideas,thinking about the future of the bridge function.What structure of bridges can be designed in unique?except the suspension bridge and so on.
It should be very easy to set up a bridge in the future, such as stitching, like the modular building blocks!

The world of the future no longer need a bridge, the car can be past any kind of groove and fly.

The future of the bridge, its load is not only very large, but also issued a colorful light. It just like the Rainbow across the Strait, so that bridge engineers to solve technical problems.
