Projeto preliminar de uma bancada didática para estudo de flexão em vigas engastadas e biapoiadas utilizando extensometria

Abstract

During the undergraduate course in Mechanical Engineering, students take several subjects, such as mechanics of solids, strength of materials and industrial instrumentation, which are taught largely with the presentation of theoretical concepts of stresses, deformations, sensors and instrumentation for measurements of quantities. For a better understanding of the content, as well as providing a practice experience, the development of tools that help in process of learning and improvement in the quality and stimulation of the student, it is a way of complementing this knowledge. The didactic bench is a device with different assembly configurations, involving different loads and beam profiles, being able to provide practical data for the study of bending in cantilevered and fixed ended beams. The present work aims to carry out the preliminary project of a didactic bench to study bending in cantilevered and fixed ended beams using strain measurements. The methodology used was projection. As a result, we have the preliminary design of a didactic bench aimed at student of Engineering courses, helping in the visualization, understanding and theoretical-practice relationship. Still the feasibility of its construction remained demonstrated, based on accessibility to materials and cost. Also stand out the alternatives of conceptions for its confection, as well as easiness and practicality of use.
