ABSTRACT:
A flexible plate is formed with a first rigidity about a first axis and a second rigidity about a second axis where the first and second axis are each perpendicular to a central axia about which the flexible plate is rotatable. The first rigidity is greater than the second rigidity such that the flexible plate may flex more easily about the second axis than the first axis, thus providing the flexible plate with an anisotropic flexural rigidity. In one embodiment, the flexible plate is formed with an eliptical intermediate portion. In another embodiment, the flexible plate includes first and second plates. Each plate has a central portion. The first plate has first foot portions and the second plate has second foot portions. The first and second foot portions have differing circumferential widths.
