Vol.17, No.3-4 (2020)

All issues

Dear colleagues,
Although certain activities regarding preparation of this issue were carried out in due time, by the end of December 2020, the beginning of 2021 brought something unexpected - we met ‘face to face’ with the coronavirus, what prolonged the publication of this issue. Such a ‘meeting’ has necessarily set a single priority – preservation of life and health. Fortunately, it was still possible to execute the relevant activities on preparing for printing, and now the readers have an issue that offers four papers from certain thematic areas of the authors’ researches. This issue of the journal MAŠINSTVO brings papers from applied researches in the field of mechanical testing, application of the planned experiment in the field of plane sample mechanics, application of QFD method in a specific production environment, and application of standard methodology in analyses using wastewater treatment plants.
In order to present scientific-research and professional capacities, the journal follows new trends and practices in multidisciplinary areas.
Also, it contains the information about the scheduled 12th Scientific-Professional Conference “QUALITY 2021”, which I warmly recommend as another important project of the Faculty of Mechanical Engineering of University of Zenica and as the opportunity for presenting the scientific-research and professional research results in certain thematic areas.
Special sections traditionally continue to present scientific- research and economic capacities from the surrounding areas.


Sincerely,
Fuad Hadžikadunić, Editor-in-Chief

DESIGN OF EXPERIMENT AND MATHEMATICAL MODEL OF BENDING STRENGTH OF SOLID WOOD PANEL

The aim of this paper is to present a sufficiently adequate and accurate mathematical model of the breaking force of a solid wood panel. For that purpose, an experiment with thirteen repetitions was designed and done. The input sizes that varied on three levels are the density of the wood and the thickness of the solid wood panel. Since the central...
