ABOUT THE GEOMETRY AND THE APPLICATIONS OF THE TWISTED SURFACES
Journal Title: Journal of Industrial Design and Engineering Graphics - Year 2015, Vol 10, Issue 2
Abstract
The helical and spiral surfaces are used in various fields. These surfaces are obtained by rotating a segment line called generatrix around directrices lines, respectively the spiral surfaces are obtained by composing simultaneously the movements of translation and rotation of a plane figure around an axis - which can be a straight line or a curved line, or around a real or imaginary surface - called core. After an overview of these surfaces, the attention of the authors will be focused on the geometrical and graphical analysis of the twisted surfaces in civil engineering branch, such as: columns, helical ramps and stairs, respectively buildings having a futuristic design.
