• Basquin’s law given by σ!" N! .!" = 600 MPa • Fracture toughness of 7.0 MPa m • Paris law constants of A=1.47x10 11 and m=3.59 (a – 15 points) You are climbing Mt. Everest, and you come across a very narrow bridge that spans over a ravine. It is constructed so that it is under a constant uniaxial tension, as shown below. You notice that the bridge has an edge crack running halfway up from the bottom. The bridge is simply supported and is fabricated from Wolverinium. The bridge thickness is 2 mm (yes – it’s very narro...
