In mathematics, an involute (also known as an evolvent) is a particular type of curve that is dependent on another shape or curve. An involute of a curve is the locus of a point on a piece of taut string as the string is either unwrapped from or wrapped around the curve. [1] The evolute of an involute is the original curve.
Involute or evolvent is the locus of the free end of this string. The evolute of an involute of a curve is referred to that original curve. In other words, the locus of the center of curvature of a curve is called evolute and the traced curve itself is known as the involute of its evolute. This is part of a special branch of geometry called ...
Introduction ¶. An involute, specifically a circle involute, is a geometric curve that can be described by the trace of unwrapping a taut string which is tangent to a circle, known as the base circle. The circle involute has attributes that are critically important to the application of mechanical gears. Circle involute from an unwrapped string.
4 days ago · Involute. Attach a string to a point on a curve. Extend the string so that it is tangent to the curve at the point of attachment. Then wind the string up, keeping it always taut. The locus of points traced out by the end of the string is called the involute of the original curve, and the original curve is called the evolute of its involute.
Aug 6, 2022 · Definition 1 1. The evolute of a given curve γ γ is another curve to which all the normals of γ γ are tangent. Definition 2 2. Given a γ γ, another curve is called an evolute of γ γ if it is an involute of the second. With the second definition, and arc-length parametrization, an internet source shows that its evolute as.
An involute (also known as an evolvent) is a form of curve in mathematics that is dependent on another shape or curve. The location of a point on a taut string as it is either unwrapped from or wrapped around a curve is called an involute of a curve. It’s a type of curve that belongs to the roulette family of curves.

The set of all centers of curvature of the curve is called the evolute of the curve. If the curve is the evolute of the curve then the initial curve is called the involute of the curve. We denote the center of curvature by the point with coordinates If the curve is given in parametric form. the coordinates of the center of curvature are ...
