Tribological humour

I recently enjoyed a good collection of scientists' favourite jokes, and sure enough, one of the very long list was funny from a tribological perspective. (That number may have increased by now with all the comments being added to the piece)



Anyway, this got me thinking. Tribology as a discipline is often taken less than seriously, but only by those who do not understand it. To the total newcomer, it might initially sound like a form of anthropology. To a scientist or engineer practicing an adjacent discipline, it might sound like just another piece of jargon that has been erected out of jealousy (or shame?) by its own practitioners. Any humour arising from these misinterpretations is unlikely to be funny to a tribologist.



The emergence of a definite strand of tribological humour, making fun of life and the world from a tribological perspective rather than deprecating tribology itself, would be a useful goal to supplement our professional efforts. It might even help to break down some interpersonal barriers, which would be helpful for all of us.



So here is the joke that got me thinking, slightly re-worded from the reference above. If you find it helpful, why not post your favourite tribological jokes here too?



Q: Two cats are sliding down a roof. Which one reaches the bottom first?

A: The one with the lower mu.

    The Stribeck curve for the interface was not analysed, so it is interesting to speculate about the sensitivity of the lubricated friction to speed. A rapid transition through hydrodynamic lift-off could contribute to the difficulty experienced in staying upright when a person unknowingly forms this tribological interface while walking.



    Their research was published in Tribology Online.



    Abstract:

    We measured the frictional coefficient under banana skin on floor material. Force transducer with six degrees of freedom was set under a flat panel of linoleum. Both frictional force and vertical force were simultaneously measured during a shoe sole was pushed and rubbed by a foot motion on the panel with banana skin. Measured frictional coefficient was about 0.07. This was much lower than the value on common materials and similar one on well lubricated surfaces. By the microscopic observation, it was estimated that polysaccharide follicular gel played the dominant role in lubricating effect of banana skin after the crush and the change to homogeneous sol.
