A) \[1.32\times {{10}^{7}}\,N/{{m}^{2}}\]
B) \[1.10\times {{10}^{15}}\,N/{{m}^{2}}\]
C) \[1.32\times {{10}^{8}}\,N/{{m}^{2}}\]
D) \[1.10\times {{10}^{6}}\,N/{{m}^{2}}\]
Correct Answer: A
Solution :
Thermal stress =\[Y\alpha \Delta \theta \] \[=1.2\times {{10}^{11}}\times 1.1\times {{10}^{-5}}\times (20-10)\]\[=1.32\times {{10}^{7}}\ N/{{m}^{2}}\]You need to login to perform this action.
