Learning outcomes of the course unit

The students will be acquainted with design and calculation of individual machine parts so that they can apply their knowledge to the construction and calculation of more complex construction units and machines.

Prerequisites

Students are assumed to have the knowledge of Fundamentals of Design and of material science, mechanics of solids, which they have obtained in 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 award are active participation in seminars and submitting all assignments. The examination comprises written and oral parts. Written part consists of a multiple-choice test and one theoretical question. The oral part consists of the discussion about the test and of a possible additional question. To pass the exam, it is necessary to reach 60% of all tasks in both parts. Classification is in compliance with the directives of BUT.
