Principle knowledge of - vectorial calculus, matrix calculus, integral calculus, and solving of differential equations.

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 51 points must be reached.

Aims

Students will be made familiar with the basic methodology and determination of stress and deformation of the simplest mock-up rod. Defining basic limiting conditions for simple and combined loading. Students will learn the basics for elasticity-solid design of bodies or machinery parts.

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

Attendance at seminars is required. One absence can be compensated by a seminar with another group in the same week, or by elaboration of substitute tasks. More absences can be compensated by special tasks according to instructions of the tutor.
