Curves of Constant Width and Odd-Sided Reuleaux Polygons

A curve of constant width is a convex, two-dimensional shape that, when rotated inside a square, always makes contact with all four sides.

A circle is the most obvious (but somewhat trivial) example. Some non-trivial examples are the odd-sided Reuleaux polygons — the first four of which are shown above.

Since they don’t have fixed axes of rotation, curves of constant width (except the circle) have few practical applications. One notable use of the Reuleaux triangle, though, is in drilling holes in the shape of a slightly rounded square (watch one of the triangle’s vertices and notice the shape it traces out as it spins).

On a less technical note, all curves of constant width are solutions to the brainteaser, “Other than a circle, what shape can you make a manhole cover such that it can’t fall through the hole it covers?”

Happy Birthtime to art singing PAUL SIMON!
Paul Simon was born today in Disneyland, USA 98 years ago today!
Paul tells people to call him Al because his real name is so difficult to pronounce!
Paul is so much shorter than his wife ART GARFUNKEL that he had to stand on a horse at their wedding!
Simon is allergic to mutton!
Paul wrote the song The Boxer about a lovely dog he once saw in a park on his lunch break!
HAPPY BIRTHTIME CARLY SIMON!
