A specimen of a 4340 steel alloy has a plane-strain fracture toughness of 45 MPa√m. It is known that the largest surface crack in a plate of this specimen is 1.07 mm long. What is the maximum stress tensile normal to this crack that the specimen can tolerate without fracturing ? Assume that the geometric parameter Y has a value of 1.0. Answer Format: X (no decimal) Unit: MPa
