Curving; curved form; (Geom.) deviation (of curve) from straight line. [Latin] Concise Oxford Dictionary

A bending; a bend, Appleton's medical dictionary.

[L., a bending] When a moving point traces out a curved line, its direction changes from point to point ; the rate of this change of direction at any point per unit length of the curve is the Curvature at the point. The Circles of C. at any point of a curve has the save curvature as that of the curve at that point ; the centre and radius of C. are the centre and radius of this circle. So far it has been supposed that all the point of the curve lie in one plane. When this is not the case, the curve is tortuous, and is said to have Double C., or more strictly curvature and tortuosity ; the helix or thread of a screw is a curve of double C. The C. of surface at any point will depend on the direction in which the C. is considered ; e.g. in the case of a common cylinder there is evidently no curvature parallel to the axis, while at right angles to the axis the C. is the same as that of the circular base of the cylinder.
