Edge Contact Lubrication
Andrew Wilkinson, Michael A. Morgan, Michael Wilkinson
In this paper we discuss the dynamics of a lubricating film separating two flat surfaces. It may be possible for the gap between the surfaces to reduce to zero at one point on the…

Hyperbolic free-surface jets
Andrew Wilkinson, Michael A. Morgan, Michael Wilkinson
If a body of inviscid fluid is disturbed, it will typically eject a jet of fluid. If the effects of gravity and surface tension are negligible, these jets travel in straight lines,…

Dynamics of pivoted slider bearings
Andrew Wilkinson, Marc Pradas, Michael Wilkinson
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…
