Equations were derived here, for the first time, that described the combined motion and rotation of small prismatic dislocation loops in stress fields. When the applied torque was balanced by the self-torque of the loop, it was shown how the solution could be obtained for the loop orientation, and how this orientation affected the glide force on the loop.
