To prepare the application of the mentioned knowledge according to the assignment of topic of PhD thesis.

Teaching methods

Individual consultations


The subject deals with kinematics and dynamics of systems of particles and a solid body, differential mechanical principles, integral mechanical principles, canonical equations and transformations, a solid body. Emphasis is placed on the kinematics of rotational motion of solid body, dynamics of solid body, such as the equivalence of systems of forces acting on a solid body, Euler dynamic equations, the Lagrange function for a moving solid body.
