Abstract
This article aims to describe an experimental procedure to be used on solid mechanics classroom to measure the Young´s Modulus as a direct constant obtained from a cantilever beam fixed at one end, loaded with a range of static deflection force. This experimental procedure is suggested to graduate students in order to develop the experimental results which are compared with classical analitycal modelling and also with finite element analysis (FEM). The geometric details of the struture are also measured and modelled by the students. The main goal of this article is to develop the perception of interconnectivity among experimental results, the classical modelling and the FEM analysis. Another important point is a worthy discussion about the results deviation which must be emphasized whenever the values have different magnitude or tendency. The writting skill of students are also worked out. It is easily observed that engineering courses are reducing the long term workload and this experimental proceedure converges to a reasonable professional qualification.
