#1

Two identical rectangular strips-one of copper and the other of steel are riveted to form a bimetallic strip. What will happen on heating?


#2

The coefficient of linear expansion of copper is more than steel. On heating, the expansion in copper strip is more than the steel strip. The bimetallic strip will bend with steel strip on inner (concave) side.
