Due to their purpose, long and narrow components like bars, beams, and columns frequently experience compressive forces along their long axis. Under the influence of critical compressive forces, such parts can lose stability and deform laterally. The precise word for this sudden or continuous loss of stability is buckling. In this case, it is not the material that ails but the component shape. Many times, the elastic zone of the bar’s stresses is still present. The clear demonstration of elastic buckling of bars under varied influences can be made with the SM-1427 device. Depending on the buckling condition, a bar is clamped or supported at both ends in this experiment. A compressive force is applied to the bar by a load mechanism. A force gauge measures the applied force and shows the results. The bar’s lateral deflection is displayed on a dial gauge. Additionally, this experiment demonstrates how other elements, such as the material and cross-sections, influence buckling behaviour. The impact of additional shear forces is demonstrated by another experiment. In this experiment, the buckling bar’s joint is subjected to a shear force via a cable and a weight. The experiment’s components are clearly organized and safely stored in a system of storage. The SM- 1400F mounting frame is used to house the full experimental equipment
