Product Details

This apparatus is designed to study the behavior of beams under unsymmetrical bending, where the load is not applied along a principal axis, resulting in complex biaxial bending and potential torsion. It allows students to analyze how different cross-sectional shapes, such as I, L, and U profiles, respond to loads applied at various angles and eccentricities. The unit includes three aluminum beams with different profiles and a versatile clamping system mounted on a 360-degree protractor, allowing the beam to be fixed at any orientation. The load application point is adjustable, enabling both centered and eccentric loading. Two precision dial gauges measure the resulting horizontal and vertical deflections, providing quantitative data on deformation of beam under combined stress states. Its primary application is in civil and mechanical engineering education for teaching advanced strength of materials and structural analysis. The key benefit is the hands-on investigation of complex bending scenarios, enabling students to visualize and measure the coupling between bending and torsion, understand the concept of principal axes, and grasp the design implications for beams in asymmetric structural applications.
