Additional information
If the rolling curve is a circle and the mounted curve is a line then the roulette is a trochoid. Roughly talking, a roulette is the curve described by a degree (called the generator or pole) attached to a given curve as that curve rolls without slipping, along a second given curve that is fixed. The mounted curve is saved invariant; the rolling curve is subjected to a steady congruence transformation such that at all times the curves are tangent at a point of contact that moves with the identical speed when taken along either curve (another means to precise this constraint is that the point of contact of the two curves is the instant centre of rotation of the congruence transformation). They're normally hand-held and crazy time statistiche hooked up by wires to the track. Thus, a mannequin of a Jaguar XK-E (185 inches or 4.7 m overall length) could be 7.7 inches (20 cm) long in 1:24 scale.
