One application is in making fireplug nuts. usually these are pentagons so a normal wrench can not remove them, but nuts in the shape of a Reuleaux triangle are even better. One can manufacture a triagular lever that will get at the pentagon, but the triangle will just roll.
They exist. i hae seen them in Red Wing Minnesota, and have been told that they have them in Minneaplois Minn. and Ann Arbor Mich.
>I've searched and searched for applications of the Reuleaux triangle >and other constant-width shapes, but can still only find, basically, >two: the Wankel rotary engine and the Harry Watt near-square drill >assembly. Does anyone know of others?
