a.) Determine the maximum normal stress developed in the bar when it is subjected to a tension of P = 16 kN. The stress concentration factors K can be found from the graphs below. b.) If the bar has an ultimate tensile stress Oult = 275 MPa, and using a factor of safety = 2, determine the maximum tension of P that could be applied to the bar.
