6. A solid cylinder made of aluminum has an initial height ho = 100mm and initial diameter do=50mm. It is subjected to a hydrostatic pressure po. The bottom face is fixed and the lateral face is unconstrained. Given that E = 70GPa and v = 0.34: (a) Determine po to cause a volumetric change of 0.005. (b) Calculate Ah and Ad (c) If the linear coefficient of thermal expansion a = 25.5 x 10-6K-, calculate the temperature increase needed to restore the original volume of the cylinder. 6.
