Rules for evaluation and completion of the course

The course-unit credit is granted under the condition of active participation in seminars and passing the seminar tests of basic knowledge (at least 10 ECTS points out of 20 must be gained). The points gained in seminar tests are included in the final course evaluation.

Final examination:
The exam is divided into two parts. The content of the first part is a cross-sectional written test, from which it is possible to obtain a maximum of 40 ECTS points. Progression to the second part of the exam is conditional on gaining at least 20 ECTS points. If this condition is not met, the exam is graded „F“. The content of the second part is a written solution of typical tasks from the profiling areas of the subject, from which it is possible to obtain a maximum of 40 ECTS points. The specific form of the exam, types, number of examples or questions and details of the evaluation will be announced by the lecturer during the semester.

Final evaluation of the course is obtained as the sum of ECTS points gained in seminars and at the examination. To pass the course, at least 50 ECTS points must be reached.
Attendance at practical training is obligatory. Head of seminars carry out continuous monitoring of student's presence, their activities and basic knowledge.

Aims

The aim of course "Statics" is to define and introduce basic terms, computational models, theories and algorithms of static problem solutions. Acquired knowledge is necessary to continue in following courses related to mechanics of solids (Dynamics, Strength of Materials). Knowledge of static problems solutions is important for structural design of machine parts.
Students will acquire basic knowledge of mechanics of solids, description and classification of force systems, determination of their characteristics and resultants as well as possibility of their equivalent replacement. Students will be made familiar with computational models of body connections without and with friction. Also provided will be the knowledge of kinematic and static analysis of supported and connected solids and mechanisms, equilibrium solution and concept of free-body diagram. Students will be able to solve static problems using basic graphic methods and calculate the internal resultant forces and moments in straight bars.
