Abstract
A method and system are provided for that allow for varying stiffness of a system by applying a low magnetic field to magnetorheological (MR) fluid in the system. The method and system include exposed patterns on facing surfaces of sliding structures. The facing patterns contain MR fluid. When a low to moderate magnetic field is applied to the MR fluid, the patterns are magnetically attracted to MR domains confined to the opposing surface, thus requiring additional force to slide the structures past each other.
