This torsion testing module is designed for analyzing the torsional behavior of rods made of different materials. The system features fully adjustable chucks, allowing users to apply angular deflection to test specimens. A precision potentiometer measures the angular twist, while a load cell records the applied torque. The unit includes three rods of different materials (solid and hollow) to compare torsional resistance, elastic shear modulus (G), and the impact of missing material on torsional stiffness. The modular design allows students to vary rod length, providing deeper insight into the relationship between length, deflection, and applied torque. The system is fully integrated with EDAQ software, enabling real-time data acquisition, analysis, and visualization through a USB interface hub. Users can study the torsion formula, compare shear modulus values, analyze second moment of area (J), and evaluate the mass-to-torsional resistance efficiency of solid vs. hollow rods. The package includes two chuck assemblies, three rods of different materials, a Vernier caliper, two cables, hexagon tools, a storage tray, and a comprehensive user guide, making it an ideal learning tool for engineering students and researchers studying mechanical properties and structural behavior.
