Table 1
Bow mass configurations and corresponding mechanical properties. Δmt, Δmc, Δmf: added masses at the tip (64.5 cm from the pivot point), clamp (15 cm) and frog (−8.6 cm). mbow: total bow mass; xCM: distance from the centre of mass to the pivot point (represented in Fig. 3); I: moment of inertia with respect to the pivot point; ΔxCM, ΔI: variation of mechanical properties compared to the reference bow A, expressed as percentages. The mechanical properties of the bow without masses are as follow: mbow = 52.2 g, I = 4.75 gm2, xCM = 20.4 cm.
