An assembly of a material consists of a brass shell fully bonded to a ceramic core. The brass shell has an outside diameter of 75mm and an inside diameter of 45mm same as the diameter of the ceramic core. At a temperature of 15°, the assembly is unstressed. Determine the largest temperature increase that is acceptable for the assembly if the normal stress in the longitudinal direction of the brass shell must not exceed 70MPa. Brass E=115GPa a = 18.7x10-6/°C α = Ceramic E=290GPa 3.1x10-6/°C
