Select all the correct answers from the list below. If a statement includes a fact and a reason, both must be correct for the statement to be correct. There is an unspecified number (N) of correct answers. For each correct answer, you will receive 5/N marks, but you will lose 5/N marks for any incorrect answer selected. Your total mark will not go negative. OA lower R value in a fatigue test of a plastic means that creep is more important relative to fatigue. The pseudoelastic design method uses a modulus value that must be appropriate for the loading time and temperature of the specific case. The stress concentration caused by a circular hole in a much larger plate is constant regardless of the hole size. The relative values of K1c and yield strength determine whether a plastic fails in a brittle manner. If a polymer displays linear viscoelastic behaviour then the curve of compliance
