Vedclass · Answer

(B) The coefficient of linear expansion for metal $A$ is $\alpha_A$ and for metal $B$ is $\alpha_B$. Given that $\alpha_A > \alpha_B$.When the temperature decreases (placed in a cold bath),both metals undergo contraction.The change in length is given by $\Delta L = L_0 \alpha \Delta T$.Since $\alpha_A > \alpha_B$,the contraction in metal $A$ is greater than the contraction in metal $B$.Because metal $A$ is on the left side and contracts more than metal $B$ on the right,the strip will bend towards the left.

$A$ bimetallic strip consists of metals $A$ and $B$. It is mounted rigidly at the base as shown. The metal $A$ has a higher coefficient of expansion than that of metal $B$. When the bimetallic strip is placed in a cold bath,it will:
