Coupler Cognates of Eight-Link Mechanisms With Ternary Links and Double Joints—Part 2

Abstract

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