The assembly shown consists of an aluminum shell (Ea - 70 GPa, da = 23.6  10-6/C) fully bonded to a steel

The assembly shown consists of an aluminum shell (Ea = 70 GPa, da = 23.6 10-6/C) fully bonded to a steel core (Es = 200 GPa, as X 11.7 x 10-6/C) and the assembly is unstressed at a temperature of 20C. Considering only axial deformations, determine the stress ir the aluminum when the temperature reaches 170C. Aluminum shell 200 mm 50 mm The stress in the aluminum is 20 mm Steel core MPa.
