Question
A bimetallic strip consists of metals X and Y. Its is mounted rigidly at the base as shown. The metal X has a higher coefficient of expansion compared to that for metal Y. when the bimetallic strip is placed in a cold bath :
Options
A.It will bend towers the right
B.It will bend towers the left
C.It will not band but shrink
D.It will neither band nor shrink
Solution
As coefficient of thermal expansion of X is more. On cooling, it will shrink more. Sothe more. On cooling, it will bend towers the left.
