WebSep 7, 2024 · where R represents the radius of the helix, h represents the height (distance between two consecutive turns), and the helix completes N turns. Let’s derive a formula for the arc length of this helix using Equation 13.3.4. First of all, ⇀ r′ (t) = − 2πNR h sin(2πNt h)ˆi + 2πNR h cos(2πNt h)ˆj + ˆk. Therefore, WebAn arc is the portion of the circumference of a circle between two radii.

I think there's no elementary formula for this. Denote arc and chord as a, b, then r θ = a, 2 r sin ( θ / 2) = b. Divide the first equation by the second, we get. θ 2 sin ( θ / 2) = a b θ = 2 a b sin ( θ / 2). Subsitute θ / 2 with u, we get. u = a b sin u. which is an equation you can't give simple solution to.
