A long strip of aluminum alloy 2024-T851 has a width of 150 mm and thickness of 8.0 mm. An edge crack of length a = 9.0 mm (Case 4 of Table 15.2) is located at one edge of the strip near the center of its length. Determine the magnitude of the axial load P that will cause brittle fracture.

Case 4 of Table 15.2:
