A dislocation line with a direction vector of 0.6i + 0.8j + 0k lies on a glide plane normal to the z-axis in a crystal. The dislocation has a Burgers vector of 0.5 nm. Calculate the force per unit length of the dislocation if a shear stress of τᵧ of 10 MPa is applied to the crystal, and:
The dislocation is an edge dislocation (3 mN/m)
