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 sciences 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:
-activity in tutorials

Aims

The objective of this course is to inform students about basic mechanical components and the methodology of their design. The course integrates findings learned in theoretical and technological courses, especially fundamentals of Design, materials Science, statics and strength of materials.

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

Participation in lectures is recommended, participation at seminars is checked and recorded - two absences are allowed.
The student must have the textbook Shigley: Mechanical Engineering Design. Examples can be solved in Mathcad or MS Office Excel.
The lectures based on Shigley´s textbook are not avalable in Moodle system.

Recommended optional programme components

Not applicable.
