The figure below shows the stress-strain behavior of a mild steel (the insert shows part of the same plot, but with different scale). This steel is used to make a rod that is 6 mm in diameter and 400 mm long. The rod is loaded in tension until an elongation of 1.2 mm is reached. A. Estimate the Yield Stress for the Steel. B. Estimate the Ultimate Tensile Stress for the Steel. C. Estimate the Elastic Modulus for the Steel. D. Estimate the %Elongation for the Steel. E. Estimate the Force acting on the rod necessary to achieve an elongation of 1.2mm. F. After an elongation of 1.2mm the load on the rod is removed. Estimate the length of the rod after the load is released. 600 500 400 500 400 300 300 200 200 100 100 0.000 0.002 0.004 0.006 Strain 0.00 0.04 0.08 0.12 0.16 0.20 Strain Stress (MPa) Stress (MPa)
