Roulette (curve) application of this is that a square wheel could roll without bouncing on a road that is a matched series of catenary arcs. Roulette (curve) In the differential geometry of curves, a roulette is a kind of curve, generalizing cycloids, epicycloids, hypocycloids, trochoids, and involutes. Roughly speaking, a roulette is the curve described by a point (called the "generator" or "pole") attached to a given curve as that curve rolls without slipping, along a second given curve that is fixed. More precisely, given a curve attached to a plane which is moving so that the curve rolls, without slipping, along
Little Matlock Rolling Mill its bearings and covered in vegetation and in need of renovation, it is the largest wheel of its type to survive in Sheffield. It has a diameter of 18ft 6in and a width of 11ft 8in with 8 cast-iron spokes to each side and 42 buckets. Above the wheel is a cast iron penstock now permanently closed. In the 1950s it was estimated that the wheel could generate 25 horse power using Volumetric flow rate data. Behind the wheel are a dam and mill race constructed to drive the wheel.
