A slipper-pad bearing with linearly decreasing gap height is being designed for an amusement park ride. Its dimensions are h0 = 1/1000 in (2.54 × 10−5 m), hL = 1/2000 in (1.27 × 10−5 m), and L = 1.0 in (0.0254 m). The lower plate moves at speed V = 10.0 ft/s (3.048 m/s) relative to the upper plate. The oil is engine oil at 40°C. Discuss what happens when the oil temperature increases significantly as the slipper-pad bearing is subjected to constant use at the amusement park. In particular, would the load-carrying capacity increase or decrease? Why?
