2. A 700mm long circular bar of magnesium alloy is loaded in tension to an elongation of 4.27mm. The load is then removed. (The stress-strain curve for the magnesium alloy is shown below.) a. Draw the stress-strain curve that represents the loading and unloading stages. Identify which part of the curve is associated with each of these two sections. 200 σ (MPa) 100 0 0 0.005 € 0.010 b. Is there residual strain after the load is removed? If so, what is the value? (An approximate answer is fine). 2.
