This video demonstrates the Matrix Torsion of Rods experiment in manual mode, where students investigate how different materials respond to applied torque. Following the included curriculum workbook, learners compare the torsional characteristics of brass, aluminum, and steel rods while collecting experimental data for analysis.
During the investigation, students install each rod, measure its dimensions, and gradually increase the angle of twist while recording the torque required at each increment. The experiment is repeated for each material, allowing students to compare torque-versus-angle relationships and better understand material properties, torsional stiffness, and structural behavior through practical experimentation.

This video demonstrates the Matrix Bending Stress experiment using data acquisition mode, allowing students to investigate how bending loads create stress within a beam. Using the included curriculum workbook, learners configure strain gauges, collect real-time measurement data, and perform engineering analysis to validate theoretical calculations.
Students begin by configuring a quarter-bridge Wheatstone bridge circuit using strain gauges and precision resistors before applying incremental loads to the beam. As each load is added, measurements are captured through the integrated data acquisition system and exported for analysis. The resulting data allows students to calculate bending stress, compare theoretical and experimental results, and gain practical experience with strain measurement techniques used throughout structural and mechanical engineering.
