Prerequisites
Students have to have basic notions of Applied Mechanics, namely they have to know concepts of equilibrium and mass centre and geometrical object centre – centróide, of concentrated force and distributed force load, of internal forces diagrams of simple structures. Not much knowledge is required from Mathematical Analyses, except of graph of functions, integral of polynomial forms, matrix calculus and methods of linear algebraic equation system solution, when homogeneous and equally when non-homogeneous.

Teaching method
Teaching involves lectures and labs. There are also office hours available to clarify some concepts and students’ doubts. Lectures intend teaching of fundamental theoretical concepts, illustrating their application on simple problems relevant for comprehensive understanding. Lectures are given in slide presentations, prepared by instructors. Students have printed version available during the respective lecture. Labs complement theoretical concepts. Active students’ participation is stimulated by the resolution of practical assignements.
