A main line crude pump trips on a bearing temperature that climbed thirty five degrees in ten minutes, and reliability engineer Aurelio Bastos finds the bearing's soft lining melted into silver streaks. Episode one hundred and five follows the clues into tribology, the science of rubbing, which Holmberg and Erdemir estimate touches about a fifth of the world's energy use. We see why friction ignores contact area, how a stopper popping out of a railway bearing in 1883 led Osborne Reynolds to explain how a shaft skis on oil thinner than a hair, and how Stribeck's curve maps the road from…
