Learning outcomes of the course unit

Students will learn the basics of the function and application of selected machine parts, especially machine parts intended for transmission of normal force and energy absorption as well as the design in terms of most frequent limit states.

Prerequisites

Students are required to have the knowledge of Fundamentals of Design, Material Science and of mechanics of solids, which they have obtained in the previous part of their study at FME BUT.

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

Terms of the course-unit credit: Written solution of all assignments (maximal number of points is 5). Two check tests (maximal number of points is 15). Maximal number of points obtained from seminar is 20. Minimal number of points necessary for course-unit credit is 10.
