Problem 11.5 Tabulated data from the tension test of steel is shown below. Calculate stress and the corresponding strain and draw a complete stress-strain curve. Draw a second stress-strain curve up to the yield-point on the same graph. Determine the following: (a) The Proportional Limit (b) Modulus of Elasticity (c) Upper and Lower Yield Points (d) Ultimate Strength An = IT ( solin ) (e) Rupture (Breaking) Strength = 0.197/in 2 (f) Percent Reduction in Area (g) Percent Elongation L = 2 in (Data for Prob. 11.5) Tension Test of Steel (Gauge Length = 2 in., Original Diameter = 0.501 in.)
