| Course abstract | |
| The aim of the study course is to master the main basic principles of theoretical mechanics. Force computation in static structures, mechanical movements of material solid body, and research into their conditions. It develops logical thinking and create a knowledge base for the acquisition of technical disciplines. | |
| Learning outcomes and their assessment | |
| Knowledge – understanding the difference between force and moment of force, the calculation of forces by the projection method and ability to compile equilibrium equations. Understanding how to determine the moment of force, and count them. Understanding of work and power in mechanics, work computation – 1. And 2. Test.
Skills – ability to look at the condition of various solid objects and structures in an abstract and analytical way, and how it effects on other mechanical systems – practical and independent works. Competences – ability to use the basic principles of theoretical mechanics in practical work and research, as well as the invention and implementation of technically innovative processes – 3. and 4. Test. |

| Requirements for awarding credit points | |
| Grade with a mark:
ofour tests must be written successfully (at least 4 points) osuccessfuly done all independent works. |
|
| Description of the organization and tasks of students’ independent work | |
| Independent work – to solve theoretical problems of mechanics, to master in depth the topics covered in lectures and perform independent works:
1st Independent work: Addition of vectors by projection method. 2nd Independent work: Addition of forces of the system of connecting forces. 3rd Independent work: Addition of forces and moments of a distributed force system. 4th Independent work: Determination of friction force. 5th Independent work: Determining the center of gravity of a figure's area. 6th Independent work: Calculation of power according to the work done by force. |
|
| Criteria for Evaluating Learning Outcomes | |
| The test with a mark is formed as the arithmetic mean of the sum of the assessments of the tests. Grade with a mark is made of the arithmetic mean of the sum of all marks (tests and practical works). | |
