Chapter 12-Strength and Stability

The two most important things that engineers or architects need to look at when building something is its strength and stability. The bigger the objegt that they want to build, the more important it is for the object to be stranger and more stable. For example, stronger materials such as steel and concrete are need when building a big bridge that allows thousands of vehicles to travel on it at the same time. However, less stronger materials such as wood can be used to build smaller bridges that are used by people or fewer vehicles. Apart from the materials used, the shape of the object is important as it provides stability for the object. This is especially important in the construction of tall buildings such as the Petronas Twin Towers ( KLCC ) and the Kuala Lumpur Tower.
