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 replacement. Students will be made familiar with computational models of body connections without and with passive resistances. 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 graphics methods.

Prerequisites

Solution of system of equations (linear, nonlinear), vectorial calculus, grounding of matrix calculus, integral calculus (line, double and triple integral)

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

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 15 ECTS points out of 30 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 70 ECTS points can be reached. Solution of several computational problems is demanded. The problems come from typical profile areas of given subject and can be 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.

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.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars is required. One absence can be compensated for by attending a seminar with another group in the same week, or by elaboration of substitute tasks. Longer absence may be made up via special tasks according to instructions of the tutor.
Course-unit credits are awarded on the following conditions:
- active participation in the seminars,
- good results in seminar tests of basic knowledge,
- solution of additional tasks in case of longer excusable absence.
Seminar tutor will specify the form of these conditions in the first week of semester.
