Hair bundle work E_hb and viscous loss E_d. Examples of E_d (dotted) and E_hb. (A) ${\overline{P}}_{\mathrm{o}}$ = 0.09 (or 0.91), 0.2 (or 0.8), and 0.5. E_hb > 0 requires 0.08 < ${\overline{P}}_{\mathrm{o}}$ < 0.92. E_hb > E_d requires 0.09 < ${\overline{P}}_{\mathrm{o}}$ < 0.91. (B) ${\overline{P}}_{\mathrm{o}}$nbsp;= 0.1 (or 0.9), 0.2 (or 0.8), 0.3 (or 0.7), and 0.5. E_hb > 0 requires 0.17 < ${\overline{P}}_{\mathrm{o}}$ < 0.83. The value E_hb > E_d requires 0.2 < ${\overline{P}}_{\mathrm{o}}$ < 0.8. Assumed parameter values: N = 60, K_g = 1.2 mN/m, X_g = 7 nm for panel A, 5 nm for panel B, F_m = 3 pN, S = 4, λ_a = 0.1 μN.s/m, K_e = 0.13 mN/m, η = 1 mPa.s, A = 100 μm², h = 1 μm, and s = 0.5 μm.
