A grade 30 gray cast iron is subjected to a load F applied to a 1 by -in cross-section link with a --in-diameter hole drilled in the center as depicted in Fig. 6–31a. The sur- faces are machined. In the neighborhood of the hole, what is the factor of safety guard- ing against failure under the following conditions: (a) The load F = 1000 lbf tensile, steady. (b) The load is 1000 lbf repeatedly applied. (c) The load fluctuates between – 1000 lbf and 300 lbf without column action. %3D - Use the Smith-Dolan fatigue locus.
