GRAPHO-ANALYTICAL STUDIES OF LINIAR EQUATION SYSTEMS
Journal Title: Journal of Industrial Design and Engineering Graphics - Year 2016, Vol 11, Issue 1
Abstract
The paper presents the solving of linear three variables system using two methods: analytic and graphic methods. The solving of a such system implies four cases: compatible system with unique solution, simple-indeterminate compatible system, double-indeterminate compatible system and incompatible (impossible) system. The correspondence between the analytic (synthetic) method and the graphic (visual) method is evident for the three space fundamental elements: point, line and plane.

GRAPHICAL RECONSTRUCTION AND FEM ANALYSIS METHOD FOR SMALL DIMENSIONAL FUNCTIONAL PARTS
The paper describes in which way an efficient and conclusive analysis procedure could be successfully applied for parts with functional role for small dimensional bearings. The main issue was to establish to what extent,...
THE ROLE OF INDUSTRIAL DESIGN IN THE PROCESS OF MODERNISATION OF RAILWAY VEHICLES
The present paper shows the role of industrial design in the process of modernisation of railway vehicles, illustrated through a study case – personal experience. The collaboration with the “Electroputere VFU Pașcani” fa...
APPLICATION OF FOLDED SURFACES IN CIVIL ENGINEERING
The paper presents the usage of folded surfaces as parts of a building system. This type of surfaces is not often used in constructions, even though the structures get to have a very special and spectacular design. The a...
TEACHING BASIC ELEMENTS IN TECHNICAL DRAWING – ORTHOGONAL PROJECTIONS
The paper presents applications developed using AutoCAD and 3D Studio MAX programs. These applications are constructed such as to enable, gradually, the development of the spatial abilities of the students and, at the sa...
STROPHOIDS, A FAMILY OF CUBIC CURVES WITH REMARKABLE PROPERTIES
Strophoids are circular cubic curves which have a node with orthogonal tangents. These rational curves are characterized by a series or properties, and they show up as locus of points at various geometric problems in the...
