This apparatus is used to investigate the elastic behavior of frames under applied loads. Frame deflection is measured in the required direction (vertical or horizontal) and at selected points, allowing comparison between theoretical predictions and experimental results. The apparatus is supplied with U-shaped and S-shaped frame models that can be configured with fixed, hinged, or simply supported boundary conditions. Load is applied using calibrated weights and hangers to ensure accurate and repeatable loading. Frame deflection is measured using two precision dial gauges mounted on magnetic stands. The apparatus features a rigid and robust chassis, which allows easy specimen mounting and minimizes experimental errors during testing.
