Knowing that one of these two specimens is polystyrene and the other is mild steel. Which of these tensile tests will be for polystyrene and which one will be for the mild steel? C. What is the Ultimate Tensile Strength (UTS) for the two specimens? Which one has higher UTS? Explain your answer. D. From the tensile test for Material A. What is the value of yield strength for this material? E. From the tensile test for Material A. Calculate the Modulus of Elasticity (Young's Modulus) for this material. F. Which material has higher plastic deformation before fracture? G. Suppose that the specimen of material A is unloaded before the yield strength point. For this specimen, sketch the elastic hysteresis loop for the elastic region of the stress-stain curve. H. Which material should you select to manufacture a mechanical part that should not change shape with great pressure? Explain your answer.|
