A bimetallic strip consists of metals X and Y. It 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

A

it will bend towards the right

B

it will bend towards the left

C

it will not bend but shrink

D

it will neither bend or shrink.

Text Solution

Verified by Experts

The correct Answer is:
B
When the bimetallic strip is kept in a cold bath, the length of X decreases faster and therefore, the strp binds towards the left.
