Learning outcomes
|
The aim of the lessons is to introduce to basic constructional elements using especially for transport means and equipment, to explain their properties and function principles and to teach students to perform necessary calculations associated with machinery design and material selection.
After completing the course the student controls the issue of machine parts used in the field of transport machinery and equipment in terms of design, materials and technology, assembly and disassembly. It can analyze the external effects acting on the components and these can then be properly dimensioned.
