The assembly shown consists of a weightless, rigid bar AC, pinned at B, that is attachedto the steel and aluminum rods. Initially, bar AC is in horizontal position; there is agap, Δ = 9 mm, between the lower end of the steel rod and its pin support at D.Neglecting the weight of the rods, compute their stresses when they are subjected to atemperature increase of 35°C and the lower end of the steel rod is attached to itssupport.
