Dynamics of pivoted slider bearings

Abstract

We obtain the full equations of motion for a wide, pivoted, slider bearing. These are used to review the choice of the optimal position for the pivot point, to discuss its response to time-dependent sliding velocity, and to determine the stability of the motion. The case of an abrupt acceleration of the slider, which results in a large transient increase in the resistive force, is surprisingly complicated. We also discuss a general transversion formula for changing the dependent variables in Stokes flow problems.
