A) \[6\times {{10}^{-6}}\]
B) \[-6\times {{10}^{-5}}\]
C) \[-6\times {{10}^{-4}}\]
D) zero
Correct Answer: B
Solution :
[c] Strain developed \[\varepsilon =\alpha \,\Delta T=(12\times 1{{0}^{-6}})(50)=6\times 1{{0}^{-4}}\] Strain will be negative, as the rod is in a compressed state.You need to login to perform this action.
