Grafické určovanie charakteristík skrutkovo-skrutkových plôch

Matúš Kuniak (1966)

Aplikace matematiky

Similarity:

This paper is connected with the preceding one of M. Kuniak (Graphical determination of characteristics of enveloping helicoidal surfaces), Apl. mat. 9 (1964), 455-466, and examines the graphical constructions associated with the geometry of enveloping helicoid-helicoidal surfaces. These may be useful for the manufacture of new helicoidal objects.

Similarity:

Properties of enveloping helicoidal surfaces, generated by helicoidal movement of developable line surfaces, are treated. A construction is given of the characteristic of an enveloping helicoidal surface, of its axial sections, of its sections by planes perpendicular to the axis of helicoidal movement, and ot the plane tangent to a characteristic at a general point of the surface.
