900 1 Engineering Stress (MPa 450 400 200 Material #2 0.0022 0.0044 Question 4 (1 point) Engineering Strain Consider the engineering stress strain diagram highlighted for materials 1 & 2. Provided that the values indicated on the graph are within the elastic region (straight-line) of the engineering stress-strain curve, what is the Young's modulus of both of these materials? E1 = 204.55MPa, E2 = 90.91MPa E1 = 409.09MPa, E2 = 181.82MPa E1 = 204.55GPa, E2 = 90.91GPa E1 = 409.09GPa, E2 = 181.82GPa Which of these two materials is more ductile than the other? Material #1 is more ductile Material #2 is more ductile Material #1 and #2 are equally ductile Question 6 (1 point) Which of these two materials is stronger than the other? Material #1 is stronger Material #2 is stronger Material #1 and #2 are equally strong Question 7 (1 point) Provided that material #1 is a stainless steel with a density of p1=7.5g/m and material #2 is a reinforced composite with a p2=2.5g/m, which of these two materials would have the higher pitch? Material #1 has a higher pitch Material #2 has a higher pitch Material #1 and #2 have the same pitch 900 1 Engineering Stress (MPa 450 400 200 Material #2 0.0022 0.0044 Question 4 (1 point) Engineering Strain Consider the engineering stress strain diagram highlighted for materials 1 & 2.
