Analysis of engineering mechanics problems solved by descriptive geometry methods

Abstract

The article shows the possibility of using descriptive geometry methods for solving problems of theoretical mechanics. The solution of problems of mechanics associated with the analysis of plane and spatial systems of forces is considered. The graphic solution of problems was carried out using the image of force vectors using orthogonal projections. A comparison of the results of graphical constructions with an analytical solution is presented.

“…On the other hand, from an educational point of view, there have been numerous initiatives to improve the skills of students in the learning and utilization of various competences of subjects related to engineering graphics which comprise the curricula in many engineering fields. There has been research on possible innovations in the practice of teaching engineering graphics [6,7], graphic thinking [8], the teaching of the discipline based on the technique of project-based learning (PBL) [9], the effectiveness of three-dimensional modelling [10], and the importance of descriptive geometry [11], as well as on solving certain mechanical problems [12]. Likewise, various studies have been carried out on the evaluation of the acquisition of competences, which either highlight the importance of spatial visualization [13], evaluate the results through an inventory of graphic engineering concepts [14], or directly establish methods to evaluate the engineering drawings made by students [15].…”
