ANALYTICAL MECHANICS | FMEN15 |

**Aim**

- give basic knowledge about the principles, the conceptions and methods in analytical mechanics based on Langranges and Hamiltons formulation of the laws of the classical mechanics.
- provide a basis for further studies in classical mechanics and quantum mechanics.

*Knowledge and understanding*

For a passing grade the student must

- provide knowledge of the most important results in the analytical mechanics.
- be able to formulate theoretical models for mechanical systems based on Langranges and Hamiltons methods.
- have some knowledge about the relation to the classical statistical mechanics and quantum mechanics.

*Skills and abilities*

For a passing grade the student must

- be able to analyze some simple models for mechanical systems using computer program (Matlab, Maple etc.).
- be able to perform an analysis of a mechanical problem and to present the results in a well-written report.
- be able to describe some engineering problems in industrial applications that can be studied using analytical mechanics.

*Judgement and approach*

For a passing grade the student must

- be able to evaluate achieved results based on the problem formulation at hand as well as physical limitations.
