Question

Draw the schematics of stress versus strain plot of a metal, and illustrate, (a) modulus of elasticity, (b) yield strength, (c) tensile strength, (d) ductility, and (e) toughness in the plot. (2.5 points)5b. A steel was subjected to a specialized and propriety heating treatment. The mechanical property of steel are: (a) Y.S = 1000 MPa (145 ksi), (b) T.S = 1380 MPa (200 ksi), and (c) % elongation at failure = 12.Please determine the maximum tensile load that can be permitted in the bar without producing extensive plastic deformation of the bar if the length and diameter of the bar is 20 mm and 1 m, respectively (5 points).
