Structures - Torsion of Rods
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.

Why Study Torsion?
Torsional loading is an important consideration in the design of shafts, drive systems, fasteners, and structural components. This experiment gives students practical experience measuring the effects of torque on different materials, helping them connect engineering theory with real-world mechanical behavior and material performance.
