An aluminum right-circular cylinder surrounds a steel cylinder as shown in the figure. The axial compressive load of 200 kN is applied through the rigid cover plate shown. If the aluminum cylinder is originally 0.25 mm longer than the steel before any load is applied, find the normal stress in each when the temperature has dropped 20 K and the entire load is acting. For steel take E = 200 GPa, ? = 12 × 10–6 /°C, and for aluminum assume E = 70 GPa, ? = 25 × 10–6 /°C.
While the ABCD rigid beam shown in the figure is simply supported from the A point, it is supported by vertical BF and CE bars from the B and C points, respectively.
