A piston-cylinder contains gas initially at 3500 kPaa with a volume of 0.03 m3. The gas is compressed during a process where pV1.25 = C to a pressure of 8500 kPaa. The heat transfer from the gas is 2.5 kJ. Determine the (a) Work and (b) change in internal energy, neglecting changes in kinetic and potential energies. (Ans: -90 kJ, 87.5 kJ)

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…
