Learning outcomes
|
The aim of the course is to acquaint students with basic principles of analytical mechanics and oscillating movements of the body systems.
After graduation of the subject student regaining more complex and more exact look on a problems of vibration in technical practice, can calculate natural frequency of systems and apply knowledge of theory of vibration on analysis of vibrating actions in a real systems.
