The assembly shown consists of an aluminum shell (Ea = 70 GPa, αa = 23.6 × 10−6/°C) fully bonded to a steel core (Es = 200 GPa, αs = 11.7 × 10−6/°C) and the assembly is unstressed at a temperature of 20°C. Considering only axial deformations, determine the stress in the aluminum when the temperature reaches 185°C.   The stress in the aluminum is −  _____ MPa.
