A steel-reinforced concrete deck can be modeled as 4 x 6 in.? elements of concrete, each with a1.0 in. diameter reinforcing bar in its center. Fabricated at 70°F, what stress

is induced in the concrete (Oconc) for every 10 degree rise in temperature (AT)? Note: Consider ONLY the axial stresses and complete the free-body diagram. (15 points)Relevant material parameters are:
