(Color online) Mechano-chemical potential ${\mu }_{\alpha }^{\mathit{sf},\mathit{mech}}$ in direction α as a function of strain for different stretch frequencies (a). SFs assemble in direction α when ${\mu }_{\alpha }^{\mathit{sf},\mathit{mech}}$ decreases, and disassemble when ${\mu }_{\alpha }^{\mathit{sf},\mathit{mech}}$ increases. Mechanical equilibrium at angle α (b).
