1. In a few words or in a single short sentence explain why it is easier to deform a piece of aluminum thai a piece of iron? | II. In a typical engineering stress-strain diagram, stress keeps on increasing after yield point due to strain hardening. In a few words or in a single short sentence explain what causes strain hardening? III. In a few words or in a single short sentence explain what kind of relationships represent thermally activated processes?. IV. Stress-Strain behavior of a hypothetical material is given below. Using 0.2 % offset yield strength method, determine (approximate) its yield strength and subsequently its modulus of elasticity. Draw (digital, manual, or copy and paste) the figure on your answer sheet and show the detail of your work. V. Determine the critical resolved shear stress on a BCC single crystal if a normal stress of 10 MPa along [100] direction causes slip system on (110) plan along (1-11), one-bar one-one, direction. Figure for Part D: 400 300 250 150 50 0.002 0.004 0.006 0.008 0.01 Strain
