The endurance limit of a specific grade of steel is same as its yield strength. The ultimate strength of this grade of steel is twice of its yield strength. A component made of this steel is loaded in tension and unloaded periodically. It is required that the component does NOT fail for at least 106 loading cycles, as per the Soderberg law. Considering a factor of safety of 2, the maximum applied tensile principal stress is
