Subject description	
Aims:
To provide to the engineering students the fundamentals of the forces and strains in the operation and design methods of electromechanical structures and devices. The students should acquire the ability to assess the forces and strains in and the operation of various structural elements
Tasks serving the fulfillment of the aims of the course:
•	Basics of engineering mechanics (statics, strength of materials) 
•	Analysis of the forces and strains in the operation of various structural elements 
The core material, the methods of education, and the requirements of the course should incorporate those knowledge, proficiencies and skills, which make possible to train electrical engineers having convertible knowledge.	
Topics to be covered: 
Equilibrium of forces in electromechanical structures and devices: basic concepts and laws, forces, basic calculation methods, methods of calculation of resultant forces, and center of gravity, determination of first order moment and of reaction force, concept of constraints
Basics of stress analysis: concept and types of strains, stress-strain functions and diagrams, general problems of design for stress, state of stress and deformation, stresses and deformations in bars 
Elements of electromechanical structures and devices: locking elements, moving/mobile elements, driving- and actuating elements.

* Class meetings accomodate  program of the lectures with calculation of examples and practical solution of problems. .			
Assessment and evaluation:	
Students are recommended to attend lectures, class meetings are mandatory.
Requirements of the signature:
- test encompassing lecture topics
- home assignment and a presentation about it. 
Admittance to examination is a home assignment and presentation submitted on due date and at least 40% level on each mandatory test.
Failed tests can be made up last week.
Missing home assigments can be made-up till the last class meeting for a fee. 
Prerequisites of the advanced examination are the minimum of mid-semestrial results of 70%. 	
Evaluation  of the exam:	
Written examination including the theoretical material of the semester. 
Evaluation is composed by scores. System of scores is made out by the responsible.
The threshold for pass mark (including the results of home assignment and mid-semester test) is 40 %. 
Pass mark will incorporate test and examination results.
