Coupler Cognates of Eight-Link Mechanisms With Ternary and Quaternary Links—Part 1

Abstract

Using the principle of stretch rotation and the principle of similarly varying triangle, existence of coupler cognates of eight-link mechanisms with ternary and quaternary links is established. It is shown that there are two additional stationary foci; each of these stationary foci yields an infinite number of cognate mechanisms for a given source eight-link mechanism.
