Cycloid plates of golden age violins are closely modeled by curtate cycloid curves. Later work indicates that curtate cycloids do not serve as general models for these curves, which vary considerably. Cycloid A cycloid is the curve traced by a point on the rim of a circular wheel as the wheel rolls along a straight line without slipping. A cycloid is a specific form of trochoid and is an example of a roulette, a curve generated by a curve rolling on another curve. The cycloid, with the cusps pointing upward, is the curve of fastest descent under constant gravity, and is
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.
