a right-handed screw dislocation lies along the [-1 1 1] direction on a (1 1 0) slip plane in a BCC crystal. They crystal is subjected to a tensile stress along the x axis. Write an experssion for the force per unit length on the dislocation due to the applied stress. This should be a vector experssion with x, y, and z componets specified
