A bimetallic strip consists of metals X`` and `Y`, it is mounted rigidly at the base as shown. The metal `X` has a higher coefficient of expansion compared to that for metal `Y`. when bimetallic strip is placed in a cold bath.

A

it will bend towards the right

B

it will not bend but shrink

C

it will bend towards the left

D

it will neither bend nor shrink

Text Solution

Verified by Experts

The correct Answer is:
C
The metal `X` has coefficient of expansion compared to that for metal `Y` so, on placing bimetallic strip in a cold bath, `X` will shrink more then `Y`. Hence to strip will bend towards the left.
