To this point, the field of lubrication has been conceptualized using several noncontiguous modes of operation- boundary, fluid-film, and dry and solid lubrication. Engineers and analysts have long had to deal with old evidence that many tribological devices, such as flat surface and centrally pivoted sliders, can act as viable bearings- contradict
