Blueprint reading; a practical manual of instruction in blueprint reading through the analysis of typical plates with reference to mechanical drawing conventions and methods, the laws of projection, etc . TnNGBNT OR DIRECTOR Fig. 92. Geometrical Constructions for Cycloid and Hypocycloid Fig. 92. If the generating circle has a diameter equal to the radiusof the director circle the hypocycloid becomes a straight line. Epicycloid. If the generating circle rolls upon the outsideof the director circle, the curve generated is an epicycloid. Fig. Curves. If a thread of fine wire is wound around acylinder or circle and then unwound, the end will describe an involutecurve. The involute may be defined as a curve generated hy a pointin a tangent rolling on a circle, knoicn as the base circle. Fig. 94.
