Table 2

Sensitivity of the mechanism to the excitation force ${\left(\partial \langle A\rangle /\partial F\right)}_{M_{\mathrm{I}}}$ (expressed in kg⁻¹) as a function of the engaged excitation inertia M_I (hand around the wrist, hand plus forearm around the elbow, whole arm around the shoulder, see Tab. 1). Sensitivity is estimated as the slope of the linear regressions displayed in Figure 6. The standard deviation of the estimates as uncertainty on the least significant digit is reported in round brackets.
