To acquire the basic engineering concepts, skills and competences in the field of checking, dimensioning and load capacity calculation of supporting structures, determination of deformation of supporting structures and determination of stresses of statically indeterminate supports. The aim of the teaching is to introduce the theoretical concepts, to illustrate them by examples close to the practice of mechanical engineering, to develop appropriate practice in solving problems.

He/she can apply the acquired technical scientific principles, rules, contexts and procedures in solving routine tasks in the field of mechanical engineering.
Requirements, evaluation and grading
Mid-term study requirements
At the end of the semester, students will write a 90-minute final exam in the lecture class. The maximum score available for the final exam is 100 points. A student who has not met the passing score may write a 100-point retake exam during the last week of the semester. Students who take a retake exam will forfeit their previous exam marks. To be admitted to the exam (§ 11 TVSZ), the end-of-semester mark must be at least 40.
Exam requirements
The end-of-semester score will be taken into account in the evaluation of the exam. A good mark (4) will be awarded for a score of 75-85 and an excellent mark (5) for a score of 86 or above. Acceptance of the mark offered is not compulsory. The exam is written. The written exam will give a maximum of 100 marks and will take 90 minutes. The mark will be awarded on the basis of the marks obtained in the written test in accordance with the TVSZ.
