What Is Curvature In Surveying A way to define curvature then would be to find the tangent circle if it exists at each point then the curvature would be the reciprocal of the radius of this tangent circle It
My textbook Thomas Calculus 14th edition initially defines curvature as the magnitude of change of direction of tangent with respect to the arc length of the curve dT ds begingroup Sure but bf T kappa bf N there means bf T s kappa s bf N s and so curvature is defined in terms of arc length It sounds to me like he is asking for a

The best way I have had it put to me is that extrinsic curvature corresponds to everyone s layman understanding of curvature before we were ever introduced to differential The curvature is then defined as the inverse of the radius of curvature So a large radius of curvature indicates a graph is nearly flat This means the curvature as the inverse of
The Riemann curvature indeed contains all information The other way around as well you can reconstruct the Riemann curvature from the sectional curvature One problem I mean when we define curvature for curves on space the curvature is meant to represent how much the curve deviates from a straight line On the other hand when reading

In spaces of positive curvature triangles bulge the sum of their angle measures exceeds 180 degrees For visualization Think of triangle on a sphere with a vertex at the North Pole and The radius of curvature is the radius of the osculating circle the radius of a circle having the same curvature as a given curve and a point So the inverse relationship of a
