Q2 (Problem 7.6) [25 points]: The edge dislocations in figure below are five Burgers vectors apart (i.e., y=5b ). The lower dislocation is immobile and the other (mobile) one is subject to an applied shear stress s=0.01G in the X direction. Here G is the shear modulus of the material. What is the separation r at equilibrium (in unit of b )? Consider only equilibrium in the X direction in the question and take the Poisson ratio of the material v=1/3
