Question
A 7075-T651 alloy is used in a structural component in an airplane. The component must
not fail when subjected to a stress of 250 MPa. Several surface flaws have been detected on the
component. What is the largest (deepest) surface flaw that could be permitted with the 250
MPa maximum stress? Use data from Table 1 and assume this component geometry and loading
condition result in a Y value of 1.25.
