A solid aluminum shaft of 60 mm diameter fits concentrically in a hollow steel tube. The aluminum shaft carries an axial compressive load of 240 kN. Assume v = 1/3 and ESt = 70 GPa. Which of the following most nearly gives the minimum internal diameter of the steel tube so that no contact pressure exists? Which of the following most nearly gives the transverse strain? Which of the following most nearly gives the axial compressive stress in the aluminum?
