A brittle material is mechanically tested in medium P in which it has surface energy γs = 0.9 J m -2 . This material has a fracture strength of 300 MPa for a given flaw size. The same solid containing the same flaws is then tested in medium Q in which γs = 0.1 J m -2 . The fracture strength (in MPa) in medium Q based on Griffith's theory is
