WebMay 19, 2013 · 6) Draw a construction circle through the centre and the point found in the previous step. This circle is the base circle for the involute. As you may know, an involute is the curve described by the end of a string wound around a cylinder. And the “string length” is the distance shown in the next step: Step 7: 7) Dimension that distance. WebThus, an equation of the evolute of the curve is .t/D.t/C 1 k n.t/: 1.3. Evolutes and osculating circles. The best-known description of an evolute re-lates it to osculating circles: The evolute of a curve is the locus of the centers of osculating circles of . The equivalence of this description and the one given before is illustrated in Figure 3.
