Product Details

This apparatus is designed to study the principles of statics by focusing on the measurement of shear force in a statically determinate beam under various point loads. It allows students to observe how forces in equilibrium create internal shear stresses and to verify theoretical predictions through direct experimental measurement. The unit features a beam mounted on two bearing supports with a low-friction hinge positioned at one-third of the span, which enables the direct measurement of shear force using integrated force gauges. The beam can be loaded at up to three points using calibrated weights and hangers, while adjuster nuts ensure the beam remains horizontally aligned. A tape measure is provided for accurate positioning of the loads, and all components are stored in an organized system for ease of use. Its primary application is in civil and mechanical engineering education for teaching fundamental concepts of structural analysis. The key benefit is the hands-on verification of shear force diagrams, allowing students to directly compare measured values with calculations based on equilibrium conditions, thereby reinforcing their understanding of internal forces in beams and their critical role in structural design.
