<![CDATA[In structural design, appropriate criteria are required to ensure that structures can safely withstand applied loading conditions while achieving optimal performance. Stress analysis is one of the most important aspects of structural engineering design. Stress in structural components can be evaluated theoretically, numerically using finite element analysis, and experimentally through direct measurement techniques. Previous studies have investigated stress analysis in structures such as wall jib cranes and beams using finite element software, as well as experimental stress measurements employing strain gauges integrated with Arduino Uno microcontrollers. In this study, stress analysis of rectangular beams was carried out using theoretical calculations, finite element simulations, and experimental measurements employing strain gauges integrated with an Arduino Uno microcontroller. The beams were designed with identical dimensions and material properties. Each beam was simply supported at both ends and subjected to different loading configurations. The stress results obtained from the theoretical, numerical, and experimental approaches showed good agreement. The highest error was observed at the lowest stress level, with a deviation of 5,44%. This discrepancy is attributed to the performance characteristics of the BF350 strain gauge sensor, which operates more effectively at stress levels above 20 MPa. Furthermore, under the same total applied load, beams subjected to two concentrated loads exhibited lower stress concentrations than beams subjected to a single concentrated load.]]>
