Entry knowledge

Basic knowledge of mathematics and physics from secondary school is required.

Rules for evaluation and completion of the course

The course is finished by credit and final examination. The credit is a necessary condition for final examination entrance. To gain credit, the students should pass two control tests during the semester. The active presence in practical classes is checked. A written exam consists of the part, in which the example is elaborated, and the theoretical part. To pass the exam successfully, both parts should be accomplished.


The definition of monitored instruction and the method of its implementation is annually updated by the guarantor of the course

Aims

Students will be acquainted with reactions and internal forces of statically determinate plane beams and frames, and geometric properties of cross-sections (centroid, second moments of area). They also will be acquainted with basic concepts and assumptions of the linear elasticity and strength theory, such as stress, displacement, and deformations and looked into dimensioning of structures.


The students will be able to solve reactions and internal forces of the plane statically determinate structures, to design centroid and second order moments of gross-section, solve simple and compound stresses to and compute strain in a section, to find materials and dimensions, to calculate deformation within bend.
