Understanding how materials behave under twisting forces is a fundamental principle in engineering. Torsion, or the twisting of an object due to an applied torque, is a critical stress that engineers must analyze when designing everything from vehicle axles to building structures. The Torsion Testing Machine (30 Nm) from TecQuipment provides a clear and practical way to explore these principles. Designed for engineering students and educators, this benchtop machine allows for hands-on experiments that demonstrate the relationship between torque and angular deflection. It serves as an essential tool for any materials science or mechanics laboratory, enabling students to move from theoretical concepts to tangible, measurable results in a safe and controlled environment.
Using this machine, students develop essential skills in material analysis and mechanical testing. The primary learning objective is to investigate the torsional properties of different materials. Students learn to calculate the modulus of rigidity (shear modulus) by applying a known torque and measuring the resulting angular twist. They can directly compare the stiffness and strength of various materials like steel, brass, and aluminum under torsional loads. This hands-on experience solidifies their understanding of elastic and plastic behavior, as they can observe the point at which a material no longer returns to its original shape. These skills are directly applicable in designing and analyzing components that experience twisting, such as drive shafts, suspension bars, and structural fasteners.

Aidex is proud to supply the Torsion Testing Machine (30 Nm) to learning institutions across the Midwest. We are committed to equipping educators and students in the region with the industry-leading tools they need to succeed. Our team ensures that schools and training centers receive dedicated support and service.
The curriculum focuses on fundamental principles of materials science and mechanics. Key topics include understanding the relationship between torque and angular displacement, determining the modulus of rigidity (shear modulus) for different materials, and observing the behavior of specimens in both elastic and plastic deformation regions under torsional load.
This machine is designed for higher education and vocational training programs. It is ideal for undergraduate students in mechanical, civil, materials, and structural engineering disciplines who are studying strength of materials, solid mechanics, and material science.
The machine is designed to test a variety of metal specimens. Standard specimen packs often include materials like brass, aluminum, and steel, allowing students to directly compare their distinct torsional properties.
The machine can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®). This optional software allows for real-time data logging, graphing, and analysis, enhancing the educational experience by automating the data collection process.
The machine includes a transparent, interlocking safety guard that encloses the test area. This guard prevents the machine from operating when open, protecting students and operators from moving parts and specimen failure.
