Curvature and torsion calculator

The torsion function w (t) that appears in the derivative of the binormal vector determines important properties of the curve. Just as the curvature measures deviation of the curve from lying along a straight line, the torsion measures deviation of the curve from lying in a plane. Analogous to the result for curvature, we have:

rational, then there are three hyperelliptic curves X 1,X 2,X 3 deﬁned over K of genus 1, 3, and 3 respectively forming a biquadratic extension of P1 such that each admits a nonconstant K-morphism to E. By this result, we prove that if all 2-torsion points of E/K are K-rational, then for each σ ∈ G K, E((K ab)σ)has inﬁnite rank, where K

We study curve motion by the binormal flow with curvature and torsion depending velocity and sweeping out immersed surfaces. Using the Gauss-Codazzi equations, we obtain filaments evolving with constant torsion which arise from extremal curves of curvature energy functionals. They are “soliton” solutions in the sense that they evolve without changing shape.

Radius of torsion. The radius of torsion is defined as the quantity σ = 1/τ. Intrinsic equations of a space curve. For a particular curve C, the curvature κ and torsion τ are functions κ(s) and τ(s) of arc length s as measured from some fixed point on C.

Curvature and torsion of a three-dimensional curve. Distinct curvatures and geodesic torsion of a curve drawn on a surface. The two fundamental quadratic forms at a point of a parametrized surface. Lines of curvature: Their normal curvature is extremal at every point. Geodesic lines. Least length is achieved with zero geodesic curvature.

Moment of Inertia Moment of inertia, also called the second moment of area, is the product of area and the square of its moment arm about a reference axis. Moment of inertia about the x-axis: $\displaystyle I_x = \int y^2 \, dA$ Space Curves There is a close connection between continuous vector functions and space curves. Suppose that f, g, and h are continuous real-valued functions on an interval I. Then the set C of all points (x, y, z) in space, where x = f (t) y = g(t) z = h(t) and t varies throughout the interval I, is called a space curve. Torsion is a measure of how much the curve twists. Both curvature and torsion are independent of the parameterization of the curve and are Euclidean invariants, i.e. they do not change under rigid body motions of the curve. Polynomial curves We often use polynomials or piecewise polynomials to represent curves. A polynomial of degree d is ...
In this way, the numerical instabilities due to the calculation of the torsion angle and potential are eliminated when performing coarse-grained molecular dynamics simulations. To systematically hinder the bending angles from reaching the \(180^{\circ}\) value, the bending potential (18) is divided by a \(\sin^2\theta\) factor:

A curvature-type tensor invariant called quaternionic contact (qc) conformal curvature is defined on a qc manifolds in terms of the curvature and torsion of the Biquard connection. The discovered tensor is similar to the Weyl conformal curvature in Riemannian geometry and to the Chern -Moser invariant in CR geometry.
