A bimetallic strip consists of metals X and Y. It is mounted rigidly at the base as shown in the figure. The metal X has a higher coefficient of expansion as compared to that for metal Y. When the bimetallic strip is placed in a cold bath ?
As, αx > αy then on colling X contracts more than Y. So, the strip bends towards X, i.e., towards left.
