Tension specimens (diameter d0 0.500 in., gage length L0 2.00 in.) made of structural materials A and B are tested to failure in tension. (a) At failure the distances between the gage marks are LAf 2.90 in. and LBf 2.22 in.; the corresponding diameters at the failure cross sections are dAf 0.263 in. and dBf 0.471 in., respectively. Determine the percent elongation in 2 in. and the percent reduction in area for these two materials, and classify each material as either brittle or ductile. (b) From these tensile tests the following data are also obtained: EA 10.0 103 ksi, (Y)A 5 ksi, (U)A 13 ksi; EB 10.4 103 ksi, (Y)B 73 ksi, (U)B 83 ksi. From the data given here, make rough sketches (to scale) of the stress-strain diagrams of materials A and B.

A soil nail proposed to be installed under the conditions given below is designed against unfactored working force of 50KN. • Ground described as sandy gravel. • Soil nail installed at an angle of 10 degrees to the horizontal and 1.2 m below the ground surface. • Nail dimensions: total length = 5 m with 60% bonded, bonded diameter = 0.35 m, debonded diameter = 0.15 m Assuming parameters not given and considering the water able to be at the surface, propose the suitable type of soil nail and calculate the theoretical working factor of safety of the installed nail against pull out. Also, briefly discuss what would jeopardise your theoretical predictions of the nail performance.
