The aluminum shell is fully bonded to the brass core and the assembly is unstressed at a temperature of 20C. Considering only axial deformations, determine the stress in the aluminum when the temperature reaches 120C. 25 mm 90 mm Brass core E = 105 GPa a = 20.9 x 106/C Aluminum shell E = 70 GPa a = 23.6 x 10-6C (AD)= MPa
