A index of motion-transmission characteristics τ of Stephenson six-link mechanisms which have two closed five-link loops including fixed and driving links was presented in the preceding paper. Here, we investigate the relation betweenτand the sensitivities of the angular displacements of the links to the deviations of the kinematic constants and the one between τ and the forces acting at the pairs to the external forces on the links. Generally speaking, the average of the sensitivities S and the one for the forces acting at the pairs F decrease rapidly in the interval [0, 0.3] and slowly in [0.3, 1] as τ increases. The τ-S and τ-F relations are approximated by the regions bounded by two rectangular hyperbolas which are modified by the coefficients determined from kinematic constants. Consequently, it is possible to estimate the values of S and F of any mechanism at the given crank angle by means ofτ.
