Table 2.

Angular velocity , torque T, and torque rate of change (mean ±r.m.s. values) for a shortened trichobothrium originally 950 μm long at a deflection angle fixed to θ _tot=1.226×10⁻³ rad (N=1, n=81). (The rate of change of the torque is determined as explained in the text and its r.m.s. from the expression where σ denotes r.m.s. value. In this formula, the r.m.s. values for T _SFS and are taken from the table entries, and that for θ _tot is estimated to be 2.45×10⁻⁵ rad from the experimental uncertainties of lever arm length and instrumental inaccuracies of the AFM.)
