RIDGE DETAIL TYPE I 283 mm 10 60ma M12 11/09mm 8.Comm 251mm 15 00mm 53.60mmm The load applied in the experiment was 4.200 KN This shows that the 'gauge length"(the length of the central portion of the sample over which the load was applied) at the start of the experiment was 50.00 mm.| To calculate the stress on the sample due to the applied tensile load you need to know the area over which this force is acting. Using information from Figure 2, show that the relevant cross-sectional area of the sample within the gauge length at the start of the experiment was 50.3 mm- (to 3 s.f.). Calculate the stress experienced by the test specimen within its gauge length, at the start of the test (to 3 s.f.). The applied load remains constant throughout the test. At the end of the test, the diameter of the test specimen shown in Figure 1 at the location where necking occurred was measured and the cross-sectional area calculated to be 20.0 mm- Based on the reduced cross-sectional area at the necking location, calculate the stress in the neck at the point of failure (to 3 s.f.)
