Product Details

This apparatus is designed to study the fundamental principles of statics by allowing students to experimentally determine both the shear force and bending moment in a statically determinate beam subjected to various point loads. It provides a practical method for observing how forces in equilibrium create internal stresses within a structural element and for verifying theoretical calculations against measured values. The unit features a beam mounted on two bearing supports, incorporating a low-friction hinge with two degrees of freedom positioned at one-third of the span to facilitate simultaneous measurement of shear force and bending moment. The beam is loaded by up to three point loads using calibrated weights and hangers. Internal forces are indicated directly by force gauges, with the bending moment calculated using a known lever arm. Adjuster nuts ensure the beam is horizontally aligned, and a tape measure allows for precise load positioning. Its primary application is in civil and mechanical engineering education for teaching structural mechanics and material behavior. The key benefit is the hands-on comparison between experimental results and theoretical predictions, enabling students to visualize and quantify the relationship between applied loads and the resulting internal shear and moment, thereby deepening their understanding of structural analysis and design.
