The following values of force are recorded in a tensile test conducted on a steel rod in a material testing laboratory. Force, F (KN) 0.2 0.4 F 0.6 0.8 1.0 1.2 1.6 The axial stress and strain for each measurement point can be computed using the following formuls: X diameter ² Area of Bar (mm²) Stress (MPa) Stress (MPa) Strain (-) . 4 Force (N) Area (mm²) = E (MPa) x Strain Stress (MPa) E (MPa)
What you need to do: 1. Compute the axial stress and strain for each measurement 2. Produce an XY plot of Force(kN) versus Stress (MPa). Place Force on the Horizontal axis. Data: Diameter of the rod (mm) - d = 7 mm Elastic modulus of steel (MPa) - E = 200000 MPa
