Abstract
A flexural member (54) in a flexural pivot is secured by a mounting member (50) to a cylindrical shell (48). The flexural member extends through an aperture (58) in an armature (44), to which it is attached by a clamp (62) that clamps one end of the pivot member (54) and is fastened by bolts (86) to the armature (44). By locating the armature (44) and the bolts (86) near the middle of the flexure member (54) rather than toward its end, the moment of inertia of the system is minimized, and its resonant frequency is thus maximized.
