Suppose that a wing component on an aircraft is fabricated from an aluminum alloy that has a plane strain fracture toughness of 28 MPa (25.48 ksi). It has been determined that fracture results at a stress of 114 MPa (16530 psi) when the maximum internal crack length is 9.1 mm (0.3583 in.). For this same component and alloy, compute the stress level at which fracture will occur for a critical internal crack length of 5.9 mm (0.23
