Question

A bimetallic strip consisting of metals X and Y is mounted rigidly at the base as shown in the figure. The coefficient of linear expansion of X is more than that of Y. If the bimetallic metal stand is kept in a cold bath then.

• A. It will bend towards right
• B. It will bend towards left
• C. It will not shrink
• D. It will neither bend nor shrink

Answer 1

Answer: (B)

It will bend towards left

As the metal X has a higher coefficient of linear expansion as compared to metal Y therefore, on placing bimetallic metal stand in a cold bath ,X would shrink more than Y.
Hence, the strip will bend towards the left.
Correct option : B
