Q2/ The 2-mm-thick bar shown in the figure below is loaded axially with a constant force of 12 KN. The bar material has been heat treated and quenched to raise its strength, but as a consequence it has lost most of its ductility. It is desired to drill a hole through the center of the 40-mm face of the plate to allow a cable to pass through it. A 5-mm hole is sufficient for the cable to fit, but an 8-mm drill is readily available. Will a crack be more likely to initiate at the larger hole, the smaller hole, or at the fillet? 40 mm 1 mm rad 34 mm 12 kN
