Purpose of the Discipline Studying 
Formulation and solving problems related to the analysis of strength, rigidity, stability and vibration of structural elements. Increasing of the professional competence level in solving problems in various fields of mechanics. As a result of the teaching the student should be able to: – to compile a design model of a component or structural element; – to perform the calculation of the stressstrain state under tensioncompression, shear, plain transversal bending, torsion, skew bending and eccentric tensioncompression; – to evaluate stresses and deformations under a uniaxial, plane and generalized stress state; – to use the differential equations of the elastic line for deflection calculating during bending; – to evaluate deflections and angles of rotation for beams and frames using the MaxwellMohr integrals and the Vereshchagin method; – to perform calculation of statically indeterminate systems by the method of forces; – to evaluate the dynamic stresses in beams under impact; – to evaluate the critical load corresponding to the loss of stability of the rectilinear form of the deformed state.
