Webstatement (1): When a bimetallic strip made of iron and brass is heated then it bends in the form of concave towards Brass. statement (2): The coefficient of linear expansion of iron is less than brass. Medium View solution > View more More From Chapter Thermal Properties of Matter View chapter > Revise with Concepts WebApr 8, 2024 · The expansion (or contraction) of any material is due to the kinetic energy of its atoms. When a material is heated, the increase in energy causes the atoms and molecules to move more and to take up more space that is, to expand. Thermal expansion is the tendency for a material to change its characteristics due to external temperature.
Why does brass bend more than iron? – Sage-Answers
WebThe 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 the 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. WebFeb 19, 2010 · Yes...brass expands more than iron because brass is a mixture of metal which would expand more when heated..while iron is one metal which is harder to be … brass single faucet
Bimetallic strip - Wikipedia
WebSo the brass will try to expand 1.5 times more than the steel. If it is truly a bimetallic strip and they are bonded, the composite should bend with the brass being on the outside … WebSince the brass has higher coefficient of expansion as compared to steel. So when it will be cooled, the brass will shrink more than steel plate and will get loosen from the steel disc. Hence option A is correct.

Modulus of elasticity is also a measure of material's stiffness or resistance to elastic deformation. If the Young modulus of metal is greater, it's stiffer. brass sledge hammer wood handel usa
