Q2) Cylindrical rod with original diameter (12mm) and original length (70 mm) made of 1020 Hot-rolled steel alloy which their yield stress (207 MPa) and Young modulus (210 GPa). Tensile test was carried on this rod and it's broken under (27.5 KN) force with final diameter (10mm) and final length (84 mm). Calculate: (A) 1- Engineering fracture stress 2- True fracture stress. (B) If you know that the Brinell hardness for this alloy (HB=111). Estimate the tensile strength of this alloy in (MPa). (C) 1- Toughness gauge. 2- The percentage of elongation.
