Prerequisites
Students must know basic notions of Applied Mechanics, namely: equilibrium, mass centre (centroid for geometric shapes), concentrated forces, distributed forces and internal force diagrams. Some background on Mathematical Analysis and Algebra is also useful, concerning function graphs, differential, integral and matrix calculus and methods for solving linear equation systems, homogeneous and 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.
