Problem 2

This question should take about 10 minutes to complete. It is an introductory level question.
If the fracture stress of a large sheet of maraging steel , which contains a central crack of length 40 mm, is 480 MPa, calculate the fracture stress of a similar sheet containing a crack of length 100 mm.
