A tensile test is conducted on a rectangular iron bar with dimensions of 4.8 mm x 15.9 mm and a initial length of 75.00 mm. The results obtained from the experiment are given in the table below. Using these data, answer the following questions. For this material; a) Draw the stress-strain curve. b) Calculate the modulus of elasticity. c) Determine the yield strength using a 0.2% offset strain and plot it on the graph (if necessary, the relevant part of the graph can be zoomed in). d) Calculate the tensile strength. e) Specify the ductility of the material as elongation. f) Calculate the toughness. g) Calculate the modulus of resilience. h) Tensile tests were conducted on five different samples from this material, and the following tensile forces were determined: 29.9-30.3-309-31.5-33.2 kN Calculate the average tensile force, standard deviation, and coefficient of variation. i) Specify where this material is used in civil engineering. (Specify the reference from which you obtained this information, such as a book, journal, etc.) i) If the material is loaded up to 30,000 N and then unloaded, calculate the modulus of elasticity, yield strength, tensile strength, and ductility for the next loading condition. k) Draw the true stress-strain curve along with the engineering stress-strain curve.
