The assembly shown consists of an aluminum shell (E, = 70 GPa, aą = 23.6 × 106PC) fully bonded to a steel core (Es = 200 GPa, as = 11.7 × 10-6PC) 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 215°C.
