A bar substance consists of two exterior steel bars and an inner impudence bar. The threebar substance is then glowing to lift the temperature by an sum T = 40 F. Let all cross-sectional areas be A = 2 in2 and L = 60 in., Esteel = 30 106 psi, Ebrass = 15 106 psi, asteel = 6:5 10‑/ F, and aimpudence = 10 10-6/ F. Determine (a) the demolition of node 2 and (b) the importance in the steel and impudence bars. See Figure P15–8.
