(A) Distribution of the angle between the two filaments, ϕ, as the polymerization rate, r2, increased. (B) Distribution of the angle between filaments as motor velocity increased. (C) Average force as a function of velocity for different rates of attachment, r0, and detachment, r1. (D) Order parameter (black) and average force (red) for the Monte Carlo simulations as motor velocity varied. r0=0.4/s, r1=0.1/s, r2=0.05/s.
