Radius of curvature 意味
WebOct 17, 2024 · Radius of Curvature refers to the radius of the approximate circle at a specific place. Radius of Curvature is defined as the distance between the vertex and the center of curvature. It is represented by the symbol R and the curvature vector length. The Radius of Curvature Formula is R= (1+ (dy/dx) 2) 3/2 / d 2 y/dx 2 . In differential geometry, the radius of curvature (Rc), R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section or combinations thereof.
