WebCounterclockwise is defined as positive curl for the same reason the cross product is defined as it is (the right hand rule -- the cross product of i and j is k). For example, torque is the cross product of the arm and force (I'll just use x for cross product). So tau = r x F. WebExamples of curl evaluation % " " 5.7 The signficance of curl Perhaps the first example gives a clue. The field is sketched in Figure 5.5(a). (It is the field you would calculate as the velocity field of an object rotating with .) This field has a curl of ", which is in the r-h screw out of the page. You can also see that a field like ...
