A) Strip will bend only when \[\frac{{{\alpha }_{A}}+{{\alpha }_{B}}}{2}>({{\alpha }_{A}}-{{\alpha }_{B}})\]
B) Strip will bend but will not elongate
C) Strip will bend with metal A as the outer side
D) Strip will bend with metal B as The outer side
Correct Answer: C
Solution :
As\[{{\alpha }_{A}}\]is more than\[{{\alpha }_{B}}\]so the length of metal A after rise in temperature will be more than that of metal B. The bimetallic strip will bend in such a manner that metal A will fall on the outer side and B will lie on the inner side of the bent strip.You need to login to perform this action.
