Fig. 6.

Variation of velocity with imposed force for the (N = 1)-state model with, as specific examples, u₀⁰/w₀⁰ = 4 and load distribution factors: (a) θ₀⁺ = −0.2, (b) θ₀⁺ = 0.4, and (c) θ₀⁺ = 1.2; as depicted in Insets a, b, and c. Cases b and c correspond to Figs. 4 and 7. Recall, as in Fig. 4, that states [0] and [1] are biochemically equivalent.
