This steel alloy specimen had an original diameter of 12.8 mm and a gauge length of 50.80 mm: i) If it were subjected to a load of 120 kN and then released, what would have been its permanent elongation? Be thorough. ii) If it were subjected to a load of 230 kN and then released, what would have been its permanent elongation? Be thorough.

Hello, the stress and cycles required for this question is Stress 1 = 420MPa at 7 cycles, Stress 2 = 360MPa at 65 cycles and Stress 3 = 130MPa at 325 cycles. Use the first three cycles (which shows how many cycles at that stress level to failure) to calculate when the specimen will fail if it underwent test of 7 cycles at 420MPa, then undergoes 360MPa for 65 cycles and finally 130MPa at 325 cycles. Will the specimen fail? Please show calculations of failure

the material had a tensile stress of 67.7 ksi then was unloaded. the original length of the specimen was 5.0 inches. show the line on the diagram you would expect the material to follow as the load was released. estimate the length of the specimen after all load was removed.

In a tensile test for an aluminum alloy, the sample is 2 inches long and 0.5 inches in diameter. The proportional portion of the tension stress-strain diagram for an aluminum alloy is shown below.  Determine the axial stress of the sample under a tensile load of 9 kips: ____ ksi. Pay attention to units and calculate your answer to 1 decimal place.
