Question 1 (see points below): An engineer was testing a new material in tension and created the following stress/strain graph. She determined from another study that nu (v) = 0.3 for this material. Note: strain is in percentage. (MPa) 550 412.5 275 137.5 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 € (%) For from this information: 1a: (2 pt) Determine the stress at 0.05% strain using the offset method: 1b: (2 pt) Determine the modulus of elasticity: 1c: (1 pt) What is the ultimate stress? 1d: (1 pt) What is the rupture stress? 1e: (2 pt) What is the modulus of rigidity? 1f: (5 pt) What would be the permanent residual strain of the material when it reached 0.5% strain and the load was released?
