Find torsion of a curve

WebDi erentiable curves with zero torsion lie in planes That a sufficiently di¡erentiable curve with zero torsion lies in a plane is a special case of the fact that a particle whose velocity remains perpendicular to a fixed vector C moves in a plane perpendicular to C. This, in turn, can be viewed as the following result. http://web.mit.edu/hyperbook/Patrikalakis-Maekawa-Cho/node24.html

WebSince we have a formula for s(t) in Equation 3.13, we can differentiate both sides of the equation: s ′ (t) = d dt[∫t a√(f ′ (u))2 + (g ′ (u))2 + (h ′ (u))2du] = d dt[∫t a‖r ′ (u)‖du] = ‖r ′ … WebFeb 2, 2015 · 1. Well, unless you have a nice system of parametric equations for the curve (which I don't believe you do), you'll have to replace, eg x' with (Delta x)/ (Delta t) (forgive the crude math notation, since SO doesn't support LaTeX). Since your intervals are all one second apart, Delta t is 1, so you can replace x' with Delta x and likewise with ... WebProof. We reparametrize the curve by the arc length. As explained in these notes, Chapter 1, Section 1.3., we obtain a new curve β given by β(s) = α(t(s)), where s is the arc length. The curvature and torsion of α at t are the curvature, respectively torsion, of β at s(t): denote it by κ. Also denote by T, N, B the Frenet frame of β at s(t). specsavers contact lens log in

For example, the circle of radius R given by r(t)=(R cos t, R sin t, 0) in the z=0 plane has zero torsion and curvature equal to 1/R. The converse, however, is false. That is, a regular curve with nonzero torsion must have nonzero curvature.
