The metal link is subjected to the axial force of p = 7 kN. Its original cross section is to be altered by cutting - a circular groove into one side. Determine the distance a the groove can penetrate into the cross section so that the L tensile stress does not exceed σallow = 175 MPa. Offer a better way to remove this depth of material from the cross section and calculate the tensile stress for this case. Neglect the effects of stress concentration.
