(1) become aware of physical phenomena in mechanics, (2) know different techniques for measuring useful variables in mechanics (extensometry, accelerometry, photoelasticimetry, stroboscopy, etc.), (3) develop the practical implementation of theoretical concepts and thus promote their assimilation, (4) knowing how to validate experimental results: critical analysis of the quality and relevance of the measurements carried out, comparing experimental results and results from theoretical or numerical approaches, (5) know how to write a report of practical work and design office, (6) deepen and apply theoretical knowledge in a practical situation.
