Mechanics of Materials Lab: Bending Stress in a Beam Analysis

This assignment is a practical report on an experiment investigating bending stress in a beam. The report begins with an introduction to the theory of bending stress, including the flexural formula and stress distribution within a beam subjected to bending moments. The experimental setup is described, which includes a loading frame, load cell, and strain gauges to measure strains at various locations on the beam. The experimental procedure involves applying incremental loads and recording strain gauge readings. The results are presented in tables and graphs, showing the relationship between bending moments and strain readings. Discussions include the calculation of bending moments and analysis of the strain data. The report concludes with references to relevant literature, providing a comprehensive analysis of the experiment on bending stress in a beam. The document covers the objective, theory, equipment used, experimental procedure, results, and discussions, and a link to a Desmos graph, all related to the practical application of mechanics of materials principles.
