The moment due to the normal and tangential forces, plotted as a function of the external torque for a typical subject. The points plotted are the moments when the load force is at the given value (5N, 10N, 15N or 20N). This subject had a mean slope of the tangential thumb vs. VF force of 1.48±0.53, and the difference between the normal forces of the VF and thumb were on average of 2.55±1.18N (VF force higher). Note that the contribution of the Mt and Mn into the total moment (M=Mt+Mn) changes with the external torque.
