1. Point your fingers in the direction of the first [[Vector|vector]]. 2. Face your palm such that the pivot vector would enter through your palm and exit through the back of your hand. 3. The direction of your thumb will be the direction of the resultant vector. 4. The direction that your fingers curl will be the direction that the [[Moment|moment]] will tend to rotate the object. When your thumb points in the direction of positive x, y, or z, then the moment is positive for that direction. Therefore, in terms of rotation, counter-clockwise is deemed the positive direction of rotation.
