What is a piece of metal in a bridge that allows it to expand and contract?
A expansion joint is a piece of metal in a bridge that allows it to expand and contract with changing temperatures without causing damage to the structure. This helps prevent the bridge from cracking or collapsing under temperature variations.
Why are two ends of a long bridge set on rollers?
The rollers allow the bridge to expand and contract with changing temperatures without causing structural damage. This is important to prevent cracking or buckling of the bridge due to thermal expansion.
Why is it necessary to know the coefficient of linear expansion of solids?
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
Why is it important to take thermal expansion into account when buliding bridges?
because in the summer, its hot and the bridge will expand and if you dont have enough room to expand the bridge will crack under pressure and in the winter the bridge may shrink a bit and might also crack. hope it helps :)
What is the purpose of the bridge pillars in supporting the structure of a bridge?
The purpose of bridge pillars is to provide support and distribute the weight of the bridge evenly, helping to prevent the bridge from collapsing under its own weight or the weight of vehicles passing over it.
Explain the purpose of an expansion joint on a bridge?
The purpose of an expansion joint on a bridge it to permit the components to expand and contract with changing temperatures without stressing the entire bridge structure. Early bridge failure would be the result of building a modern bridge without expansion joints.
What materials is the London bridge made of?
It is a pre-stressed concrete box girder bridge.
What material where used to build the London bridge?
