A method to evaluate a configuration of a constrained mechanism is developed in this paper. Based on inertia tensor analysis of the mechanism, we propose two new indices, "effective inertia" and "idle inertia". They can be defined at any point in the mechanism, and they respectively represent the efficiency and the loss in the transfer of kinetic energy between the mechanism and the external environment. Modeling human as articulated rigid bodies, we apply this method to evaluate the driving postures in terms of steering usability. The indices accurately pointed their right steering wheel position and right angle of accelerator pedal. The driving posture at the right steering position was analyzed with the holding points changed. The result suggests that our steering wheel holding behavior make sense from a mechanical viewpoint. Furthermore, it is demonstrated that we can equalize different drivers' usability with nonlinear optimization and the inertia eigen space method.
