For the plane truss shown in Figure P15–9, bar element 2 is subjected to a uniform temperature rise.


For the flatten truss shown in Figure P15–9, bar component 2 is subjected to a unvarying latitude stir of T = 10 C. Let E = 210 GPa, A = 12:5 cm2, and a = 12 10-6/ C. What latitude exexchange is needed in bars 1 and 3 to oust the force due to the unvarying latitude stir in bar 2? Show ample operation to confirm your confutation. Use a longhand disconnection.
