Product Details

This apparatus is designed to demonstrate the principles of statics by studying bending moments in a statically determinate beam subjected to various point loads. It allows students to experimentally determine bending moments and verify equilibrium conditions, illustrating how external forces affect a rigid body and how reactions at supports can be calculated. The unit features a beam mounted on two bearing supports with a low-friction hinge positioned at one-third of the span to simulate a point where bending moment is measured. The beam can be loaded at up to three points using hangers and a set of calibrated weights. A force gauge connected to a fixed lever arm quantitatively indicates the bending moment, while adjuster nuts ensure proper horizontal alignment of the beam. A tape measure is included for precise positioning of the loads, and all components are stored in an organized system for convenience. Its primary application is in civil and mechanical engineering education for teaching fundamental concepts of structural mechanics. The key benefit is the hands-on verification of theoretical calculations, enabling students to directly compare measured bending moments with those predicted by static equilibrium equations, thereby reinforcing their understanding of force distribution in beams and other structural elements.
