Comparative Flexural Analysis of Cantilever Beam at Various Loads Using Analytical, Computational and Experimental Techniques

Measurement of strain and stress plays a crucial role in advancing research in mechanical engineering. In this paper, the bending strain and stress of the steel cantilever beam subjected to concentrated loads at the free end are investigated using analytical, experimental, and numerical approaches. The experimental investigation was carried out through the use of a strain gauge sensor connected with a Wheatstone quarter-bridge configuration. The strain gauge used in this experiment is interfaced with the NI SignalExpress software in conjunction with the NI modules to ensure accurate data acquisition. The experimental measurements provide essential benchmark values for comparison with the numerical results. The numerical simulation is developed using ANSYS Workbench. The comparison results show that the experimental values have good agreement with the simulated FEM and analytical values. The findings of this study provide valuable insights into the bending strain characteristics of steel cantilever beams and contribute to the advancement of mechanical engineering research.
