A large part in a turbine-generator unit operates near room temperature and is made of ASTM A470-8 steel ( ). A surface crack has been found that is roughly a semi-ellipse, with surface length 2c= 50 mm and a depth a= 15 mm. the stress normal to the plane of the crack is 250 MPa, and the member width and thickness are large compared to the crack size. What is the safety factor against brittle fracture? Should the power plant
