[ noun ] (geometry) the radius of the circle of curvature; the absolute value of the reciprocal of the curvature of a curve at a given point
Used in print (Harry H. Hull, "The Normal Forces and Their Ther...)The relative forces can be calculated from the various radii_of_curvature if we assume : ( A ) The surface_tension is uniform on the surface of the drop . Just as the pressure exerted by surface_tension in a spherical drop is * * f and the pressure exerted by surface_tension on a cylindrical shape is * * f , the pressure exerted by any curved surface is * * f , where �g is the interfacial_tension and * * f and * * f are the two radii_of_curvature . If a is the major_axis of an ellipsoid and b and c are the other two axes , the radius_of_curvature in the ab plane at the end of the axis is * * f , and the difference in pressure along the a and b axes is * * f .
