Structures: Newspaper Bridges / Page 1 of 4

In this activity, the student will begin to have an empirical understanding of how the structure is designed to withstand the load or designed to withdraw. This event provides an opportunity to talk about the bridge the student knows. There are obvious examples such as Golden Gate and Brooklyn Bridge, but an example that is not noticeable even less may be interesting as well. Look for Ogawa, footbridge bridge, and even the road that passes through the second floor of the building. Discussion of these examples encourages students to bring their experiences and understanding of the bridge into activities, thereby linking their school experience to the outside world.

In order to design a safe bridge structure, the engineering design process includes the following steps: 1) to fully understand the problem, 2) to determine potential bridge loads, 3) 4) The material is resistant to the highest load. One of the most important steps in the design process is to understand the problem. Otherwise, the hard work of design can be wasted. For example, when designing a bridge, if the engineering team does not understand the purpose of the bridge, their design may be completely unrelated to solving the problem. If you are told to design a bridge crossing the river without knowing it, you can design a bridge for a train.

What is a bridge? A bridge is a structure that provides a continuous passageway to a watershed, road, or valley. Each bridge looks different from the others. Their bridges have different structures. There are nine major bridges. Bridge engineers use many geometries to design different bridges. Without geometric shapes, the bridge is not safe. That bridge has been around for a long time. The earliest bridge could have been formed by laying one or more logs over a stream or by stretching a rope or cable in a narrow valley. These kinds of bridges are still in use. The wooden beam bridge seems to be the most common type known to ancient people, but according to the tradition, the Brick Arch Bridge was built in Babylon around 1800 BC. Other forms such as simple suspension bridges and cantilevered bridges are known to be used in ancient India, China, Tibet. Pontoon was used for military investigation by Persian princes Darius I and Zelkus I.
