An aircraft component is fabricated from an aluminum alloy that has a fracture toughness of 48.0 MPa/m^1/2. It has been determined that fracture results at a stress of 380MPa when the maximum (or critical) internal crack length is 4.7mm. For this same component and alloy, will fracture occur at a stress level of 280MPa when the maximum internal crack length is 7mm? Why or why not?
