A) 3/2
B) 1
C) 2/3
D) ½
Correct Answer: A
Solution :
Thermal stress \[I=0.5\] The rods are heated such that they undergo same increase in temperature. So, \[\frac{1}{2}iBL\] The stresses developed are also equal. \[{{\tan }^{-1}}\left( \frac{3}{4} \right)\] \[{{\tan }^{-1}}\left( \frac{4}{5} \right)\] \[{{\tan }^{-1}}\left( \frac{4}{3} \right)\] \[{{\sin }^{-1}}\left( \frac{3}{5} \right)\]You need to login to perform this action.
