Fig 8. Plot of $k_m(\tilde{f},\tilde{\kappa })$ (in real units of [s⁻¹]) for three different values of scaled substrate stiffness $\tilde{\kappa }$.

The red cross represents the value of the dimensionless scaled force ${\tilde{f}}_{\mathrm{\text{eq}}}$ in cell equilibrium, corresponding to the steady state value of α. In the lowest plot (for stiff substrate), the red cross corresponds to a value of k _m = 0.01 s⁻¹.
