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: active participation at seminars, written solution of all assignments, 2 basic knowledge tests with possibility of answers selection. Any test must not be evaluated by F grade.
Examination requirements: exam evaluation includes 20% of the assessment from seminars and 80 % of multiple choice test assessment. Any part of the exam must not be evaluated by F grade. The test is conducted using electronic testing system.
