6. A structural bridge component in the form of a wide plate is to be fabricated from a steel alloythat has a plane strain fracture toughness of 68.9 MPa vm

and a yield strength of 760 MPa. Theflaw size resolution limit of the flaw detection apparatus is 2.0 mm. If the design stress is one-half of the yield strength and the value of Y is 1.0, determine whether or not a critical flaw forthis plate is subject to detection.[4 points]
