- Course objectives
- Course of theoretical mechanics, a part of the course of theoretical physics.
Main objectives: to master the fundamentals of Lagrangian and Hamiltonian approaches to mechanics, to understand the basic mechanics of rigid body, theory of elasticity and fluid mechanics and to be able to solve problems from these areas.
- Learning outcomes
- The student will be, after finishing the course, able to: solve mechanical problems using Lagrange equations; identify integrals of motion in a given situation; analyse the problem of motion in the central potential; plot phase trajectories for simple systems; clearly explain the meaning of the tensors of stress, deformation and inertia and describe their propeties; solve simple problems of liquid flow and elastic body deformations.
- Hamilton variation principle, Euler-Lagrange equations, curvilinear coordinates, the form of Lagrange function.
- Conservation laws - cyclic coordinates, generalised energy, conservation of momentum and angular momentum of an isolated system, theorem of E. Noether.
- Integration of equations of motion - one-dimensional motion, motion in central potential, effective potential, Kepler problem, scattering of particles, cross-section, Rutherford formula.
- Hamilton canonical equations, canonical transformations, Poisson brackets, Liouville theorem, motion as a canonical transformation, Hamilton-Jacobi equation.
- Basics of rigid body mechanics - tensor of inertia and its diagonal components and deviations moments, angular momentum, rotational kinetic energy, motion of a spinning top, Euler equations.
- Theory of elasticity - displacement vector, deformation tensor, stress tensor, surface and volume forces, Hooke law for isotropic medium, equation of equilibrium for isotropic bodies.
- Hydrodynamics - the vector field of velocity, streamlines, tensor of velocity of deformation, vorticity, continuity and Bernoulli equations, equations of motion of fluids (Euler equations, Navier-Stokes equations).

- Teaching methods
- 2 hours of lecture + 2 hours of tutorials per week. The lecture presents the theory and the tutorials are devoted to exercising the theory by solving problems.
- Assessment methods
- Final examination has both written and oral parts. Home work is required during semester. To be able to sit for the examination, the student must gather enough credits that can be obtained for home work and for written tests during semester.
- Language of instruction
- Further Comments
- The course can also be completed outside the examination period.
The course is taught annually.
The course is taught: every week.
