Learning outcomes
|
Derivation and application of basic equation of elasticity theory. Technical problems - torsion and bending. Formulation of boundary value problems. Introduction to variational methods. Basics of fluid mechanics and thermodynamics.
The subject provides basic orientation in selected parts of physics necessary for later specialized study - understanding the processes, quantities and equations.
