CE250. Mechanics I (Strength of Materials) (ects: 7)
This course is aiming to provide knowledge concerning the type of loading cases, the physical meaning of stress and strain as well as analytic procedures for their determination. Furthermore, significant target of this course is also to teach the students the methods for dimensioning structures.
