A frequent poster on an automotive group joined in a discussion about connecting rods from engines in service showing some local discoloration presumably due to having been hot.
After the big ends and pin ends were discussed, and "we" moved to localized discoloration of the beam of the rod, the poster said this -
"But do not assume that heat is not generated locally on the beam of the rod. Heat is generated by the flexing of the rod -- it is not a theoretically rigid construct. If there are flaws or stress raisers that area can easily overheat and leave witness marks or color change."
I'm thinking that post may belong in an episode of "Big Bang Theory"
