9.38 The assembly shown consists of an aluminum shell (E. = 70 GPa,
a, = 23.6 X 10°C) fully bonded to a steel core (E, = 200 GPa,
a, = 11.7 × 10-ºC) and is unstressed at a temperature of 20°C.
Considering only axial deformations, determine the stress in the
aluminum shell when the temperature reaches 180°C.
