Learning outcomes of the course unit
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.
Solution of system of equations (linear, nonlinear), vectorial calculus, basics of matrix calculus, integral calculus. Knowledge of the software Maple.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
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: Written part of the examination plays a decisive role, where the maximum of 80 ECTS points can be reached. Solution of several computational problems is demanded. The problems come from typical profile areas of given subject and supplied by a theoretical question, proof, etc. The lecturer will specify exact demands like the number and types problems during the semester preceding the examination.
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 points must be reached.
Language of instruction
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.
Specification of controlled education, way of implementation and compensation for absences
Attendance at practical training is obligatory. Head of seminars carry out continuous monitoring of student's presence, their activities and basic knowledge.
