Abstract In this experiment, a simply supported beam is used and the variations of deflection of a simply supported beam with load, beam thickness and material are investigated. It is found that the deflection of the beam changes linearly with the load and as the beam thickness increases, the beam deflection decreases. In addition, since different materials have different modulus of elasticity, deflection of different materials under a specific load is different. Depending on the results of the experiment, it is observed that the measured deflection values under different loads and for different materials overlap the Euler-Bernoulli Beam Theory.
Introduction Beams can be described as a structural element that withstands load. Although beams are considered mainly as building structural elements, automobile or machine frames also contain beams to support the structure. Some applications require beams to support loads that can bend the beams, therefore it is important to observe the behavior of the beams under bending forces and which parameters have an effect on this behavior. If the maximum deflection that the beam can resist were not taken into consideration in the design process, there would be some serious failures in structures that can lead to some serious outcomes. In this experiment, an overhanging beam is used, which can be defined as a beam simply supported at two fixed supports and having both ends extended beyond the supports. In order to conduct this experiment and to investigate the variation of deflection of a simply supported beam, an apparatus that contains two support points is used. During the experiment, the relationship between the deflection and the load is to be observed by changing the load applied to the
