Question

7.Bridges constructed using steel materials expand on heating during
summer, how do you plan to accommodate this expansion of increased
length of bridge.?

Answer 1

Answer:

Materials expand or contract when subjected to changes in temperature. Most materials expand when they are heated, and contract when they are cooled. When free to deform, concrete will expand or contract due to fluctuations in temperature. The size of the concrete structure whether it is a bridge, a highway, or a building does not make it immune to the effects of temperature.
