In this experiment we come to know how different amalgamation of loads and distances causes the variation of bending moments across the length of a beam. Another attribute of this report is that it envisage about the agreement of theoretical values calculated with those which are calculate during the experiment. The experiment was designed to foster creative thinking and to make the study of structural analysis more meaningful by incorporating the concept of design, model, test, observe and discuss.

Firstly, to compare the theoretical internal moment with the measured bending moment for a beam under various loads, and Secondly, to measure the shear force at a normal section of a loaded beam and to check its corroboration with theory. The basis of this experiment is to give students a hands-on experience and give them an idea of structural analysis and its application in Material Science and Engineering through real-life examples such as bridges, etc. This experiment bears exemplary significance in the careers of Material Students as it integrates Material Analysis, Stress Analysis, Structural Study, Force Application and Theoretical Calculations. Normally a beam is analysed to obtain the maximum stress and this is compared to the material strength to determine the design safety margin. It is also normally required to calculate the deflection on the beam under the maximum expected
