Understanding the internal forces within a structure is a fundamental principle of engineering. The Bending Moments in a Beam apparatus from TecQuipment provides a clear, physical demonstration of these unseen forces. It is designed for engineering students to bridge the gap between abstract theory and practical application. The core of the equipment is a simply supported beam with a carefully engineered ‘cut’. At this cut, a system of load cells precisely measures the two key internal reactions to external loads: the shear force and the bending moment. Students can apply various loads at different points along the beam and move the cut to new positions. This hands-on interaction allows them to directly observe how forces and moments change, providing a foundational understanding of structural behavior that is essential for civil, mechanical, and structural engineering disciplines.
Using this apparatus, students develop a tangible understanding of core structural mechanics concepts. The primary application is the experimental construction of shear force and bending moment diagrams. Students learn to systematically measure these values at various points along the beam’s span. This process reinforces the direct relationship between applied loads, shear force, and the resulting bending moment. A critical skill developed is the ability to compare this empirical data directly with theoretical values calculated using principles of static equilibrium. This validation of theory with physical evidence solidifies complex concepts, helping students to intuitively grasp how load paths and internal stresses are distributed within a simple structure.

Aidex is proud to supply the Bending Moments in a Beam 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.
The curriculum focuses on fundamental structural mechanics principles. It covers the creation of shear force diagrams, the development of bending moment diagrams, the relationship between applied loads and internal forces, and the principle of static equilibrium. Students also learn to compare theoretical calculations with direct experimental results.
This apparatus is designed primarily for undergraduate students in engineering disciplines. This includes those studying civil engineering, structural engineering, and mechanical engineering who need a practical understanding of beam theory and structural analysis.
The beam is sectioned at a specific point, known as the ‘cut’. This cut is connected by a mechanism with two load cells. One measures the vertical shear force directly, and the other measures the force that translates into the bending moment at that point, providing real-time, quantitative data.
Yes, the Bending Moments in a Beam apparatus is fully compatible with TecQuipment’s Versatile Data Acquisition System (VDAS®). This allows the force and moment data to be sent to a computer for real-time graphing, analysis, and storage, enhancing the learning experience.
The equipment includes a set of calibrated weights and hangers. Students can apply single point loads, multiple point loads, and combinations of loads at various positions along the beam to study their effects on shear force and bending moment distribution.

If your wish list isn’t clear, your dreams won’t be either. When you model thoughtful planning for your CTE program, you’re teaching students how to turn their own dreams into reality.
