Structures - Bending Moments
This video demonstrates the Matrix Bending Moments experiment operating in manual mode, giving students a practical understanding of how loads create bending moments within a beam. By following the included curriculum workbook, learners collect real experimental data and compare measured values with theoretical calculations, reinforcing key principles of structural engineering and mechanics.
During the experiment, students move a fixed load to multiple positions along the beam while the integrated load cell measures the resulting forces. The measured data is recorded, analyzed, and used to calculate support reactions and bending moments before being plotted on a graph for comparison with theoretical predictions. This hands-on investigation helps students visualize how load position influences internal beam forces and structural behavior.

Why Study Bending Moments?
Understanding bending moments is fundamental to structural and civil engineering. This experiment allows students to investigate how beams respond to different loading conditions, validate engineering theory through experimentation, and build confidence interpreting structural analysis using real-world measurements.
