How does thermal expansion affect bridges?, Socratic

Jul 16, 2014 · Thermal expansion can affect bridges with either expanding or contracting the bridge (or, by essentially distorting it's shape). If a bridge gets very heated, the road bed will expand. On the other hand, if the bridge is cooled, the road bed will retract. These changes in the bridge may seem initially insignificant, but with constant temperature changes, there will be constant and pervasive ...sp.info Rail profile - WikipediaThe rail profile is the cross sectional shape of a railway rail, perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section approximate to an I-beam, but asymmetric about a horizontal axis (however see grooved rail below). The head is profiled to resist wear and to give a good ride, and the foot profiled to suit the fixing system.Some results are removed in response to a notice of local law requirement.
