Show that the crack grows from its tip B, and plot the variation of crack extension angle and critical stress of fracture versus b/a (0 < b/a < 1) for , 1.8, 2.2 and 3.0, when the load P is tensile or compressive.

7.10.A crack of length 2a in an infinite plate is subjected to a concentrated force Q applied at the point x = b (Fig. 2.​16a). The stress intensity factors at the crack tip B are given in Problem 2.5, while the stress intensity factors at the other crack tip A can be obtained from symmetry considerations as
