Eqn. 14-34 is same as 14-30. Figure 14-5 is a plot of the variation of Fx with distance x, using equation 14-34. Where x is expressed in units of y. Curve A is for dislocations of the same sign; curve B is for dislocations of opposite sign. Note that dislocations of the same sign repel each other when x > y, and attract each other when x < y.
