A milling operation was used to remove a portion of a solid bar of square cross section. Forces of magnitude P = 18 kN are applied at the centers of the ends of the bar. Knowing that a = 30 mm and σall = 137 MPa, determine the smallest allowable depth d of the milled portion of the bar. The smallest allowable depth d of the milled portion of the bar is mm.
