For the following problem, unless noted otherwise, refer to Appendices F and/or G for necessary mechanical properties. Unless noted otherwise, assume gray cast iron, as appropriate.

A 1.0-in.-diameter hole is drilled on the centerline of a long, flat steel bar that is . thick and 4 in. wide. The bar is subjected to a tensile load of 30,000 lb. Calculate the average stress in the plane of the reduced cross section and the maximum tensile stress immediately adjacent to the hole.
