| Abstract: | Nongrashof Planar Four-link mechanisms generate complex coupler curves when the driving link oscillates in such a manner that the coupler and driven links belong to the different composition loops in going and returning respectively. In this paper, these curves are classified according to the numbers of the nodes, the inflection points, the maximum curvature points and the number of rotations of the curve. |
