Bimetallic Strip | Thermal expansion | Thermodynamics | IITJEE Physics | Ankit Rathore's Physics Lab
A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated. The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature. The metal with a higher coefficient of thermal expansion is on the outer side of the curve when the strip is heated and on the inner side when cooled.
