A solid object of AISI 302 steel at a temperature of 850?C is quenched in mineral oil at a temperature of 25?C. The oil is contained in a well-insulated cylindrical tank that has a diameter of 1 m and a height of 1 m. The mass of the solid steel object is 8 kg. The specific heat and density of the oil are 1,950 kJ/kg-K and 890 kg/m3, respectively.
If the bar is subjected to centric forces of magnitude P = 30 kN and knowing that EA = 70 GPa and EB = 105 GPa, determine the normal stress (a) in the aluminum layers, (b) in the brass layer.
