 30 hours per semester

Learning outcomes

The course is aimed at gaining basic knowledge from the area of calculations of stresses and deformations of linear elastic bodies, as well as skills in independent solution of simple practical tasks.
The student has the skills needed to design machine parts subjected to tensile, compression, flexure, torsion, shear and combinations thereof.

Prerequisites

Knowledge of issues to be addressed within the thesis, especially of matematics and mechanics.

Assessment methods and criteria

Grade (Using a grade system), Oral examination, Preparation of a presentation
Credit: attendance at the exercises min. 80%, submission of the required presentations in the terms given. Examination: knowledge of the curriculum content already dealt with. The result of a subject examination is expressed on a sixpoint scale: A "výborně" (i.e. "excellent"), B "velmi dobře" (i.e. "very good"), C "dobře" (i.e. "good"), D "uspokojivě" (i.e. "satisfactory"), E "dostatečně" (i.e. "sufficient"), F "nedostatečně" (i.e. "fail").
