The aluminum shell is fully bonded to the brass core and the
assembly is unstressed at a temperature of 158C. Considering
only axial deformations, determine the stress in the aluminum
when the temperature reaches 1958C.
2.48 Solve Prob. 2.47, assuming that the core is made of steel
(Es 5 200 GPa, as 5 11.7 3 1026/8C) instead of brass.
