The aluminum shell is fully bonded to the brass core and the assembly is unstressed at a temperature of 15 C. Determine the highest temperature the whole structure can be increased to if the normal stress in the brass core is not to exceed 10 ksi. 25 mm 60 mm Brass core E = 105 GPa a = 20.9 10-6C Aluminum shell E 70 GPa a = 23.6 10-6C
