Does anybody remember the CR designer challenge from the 1980s?
The CR stood for Chicago Rawhide, whose main business is oil seals, from the web it looks like they've been taken over by SKF. I don't know whether that CR has anything to do with the CR of this forum, I tried to find out but it didn't jump out at me.
The challenge consisted of 10 questions with multi-choice answers and ran for several years, with some fairly valuable prizes. Mostly interesting questions, often with a sting in the tail. My then boss would never let work get in the way of a good technical wangle, and we'd discuss it at length.
