NEED AN ANSWER ASAPAn aircraft component is to be fabricated from an aluminum alloy that has a plane strain fracture toughness of 45 MPa m and a yield strength of 500 MPa. It has been determined that fracture results at a stress of 250 MPa when the maximum internal crack length is 9 mm. For this same component and alloy, determine critical internal crack length that will result to fracture if the design stress is three-fourth of the yield strength. If the available flaw detection apparatus has a resolution limit of 3 mm, will the crack in (1) be detected? Why or why not? Show complete solution
