Introduction

In this report, we will be looking at the 4 major types of bridges and the main factors which needed to be considered when building bridges. To discover and explain the physics techniques and ideas involved with structure of bridges. For each type of bridges and particular factors which needed to be considered when building bridges, there will be analysis for the real cases of bridges around the Earth of some of them. The purpose is to related the physics principles to the bridges which already been build.

Bridges are familiar to everyone nowadays. They are one of the most useful constructions in every part of the World. They have solved so many problems of transportation, making people travel more conveniently from place to place. All bridges are designed to allow loads to cross obstacles. Generally the loads will either be vehicular traffic, pedestrians or animals. In order to prevent any accidence happening, bridges are carefully designed by engineers. There are lots of physics concept to be applied in order to build bridges, e.g. materials matters, forces (compression, tension) acted, resonance, thermal expansion.

Bridges can twist or bend under severe weather
