X: 9 Y: 0 170505354 *If the load is defined as (XY) N, it means that the load is 54 N L. Y X 1) A metal bar 100 mm long and having a square cross section 20 mm on an edge is pulled in tension with a load of 89000 N, and experiences an elongation of (0.05*XY) mm. Assuming that the deformation is entirely elastic, calculate the elastic modulus of the metal. 2) For a bronze alloy, the stress at which plastic deformation begins is (200+XY) MPa, and the modulus of elasticity is 115 GPa. (a) What is the maximum load that may be applied to a specimen with a cross-sectional area of 325 mm2 without plastic deformation? (b) If the original specimen length is 120 mm, what is the maximum length to which it may be stretched without causing plastic deformation? 3) Figure shows the tensile engineering stress-strain behavior for a steel alloy. (a) What is the modulus of elasticity? (b) What is the proportional limit? (c) What is the yield strength at a strain offset of 0.002? (d) What is the tensile strength? 600 500 400 500 T Stress (MPa) 300 400 300 Stress (MPa) 200 200 100 100 0 0.000 0.006 0.002 0.004 Strain 0 0.00 0.04 0.12 0.16 0.20 0.08 Strain
