A beam is a structural component that resists bending primarily to support loads. Compressive, shear, and tensile stresses are experienced internally by the beam. The apparatus is used to measure the deflections and slopes of a beam that is bending and to compare those readings to those obtained from differential equation and Area Moment Method calculations. The beam has two adjustable height end supports with anm interchangeable knife edges and a cantilever end clamp. For point loads, load hangers are utilised, while many weights are used for uniform loads. Dial gauges are used to measure slopes and deflections. In both building and mechanical engineering, beams are important structural components. A beam is a bar-shaped structural element that is loaded both parallel to and perpendicular to its longitudinal axis. Its cross-sectional dimensions are significantly lower than its length. The force perpendicular to the longitudinal axis causes in bending of the beam,, which is a deformation of the beam. The beam is considered as a one-dimensional model based on its size. The stress and strain that arise from applying a load to a component are the subject of the study of material strength. A straight beam is a good example of many key ideas in material strength. SM-1404’s investigation beam can be assisted in a variety of ways. This results in systems that are statically determinate and indeterminate and can be loaded by up to four sets of weights. The points where the load is applied are movable. The resulting deformation is measured by three dial gauges. Three articulated supports that have built-in force gauges immediately indicate the support reactions. The height of the articulated supports can be changed to account for the deadweight of the beam under inquiry. The effect of geometry and elastic modulus on the deformation of the beam under load is demonstrated using numerous beams of various thicknesses and compositions. The experiment’s components are all organised clearly and kept safe in a storage system. The frame contains the entire experimental setup. The comprehensive course materials outline the foundations and offer a step-by-step walkthrough of the experiments.
