A bimetallic strip consists of metals \(A\) and \(B\). It is mounted rigidly as shown. The metal \(A\) has higher coefficient of expansion compared to that of metal \(B\). When the bimetallic strip is placed in a cold both, it will :
- A Bend towards the right
- B Not bend but shrink
- C Neither bend nor shrink
- D Bend towards the left
Answer & Solution
Correct Answer
(D) Bend towards the left
Step-by-step Solution
Detailed explanation
\(\alpha_{ A }>\alpha_{ B }\) Length of both strips will decrease \(\Delta L _{ A }>\Delta L _{ B }\)
