Bending moment in a beam - Lab Report Example l try to explain how bending occurs in simply supported beams, and it will also compare measured or the experimental values of bending moments with that of the theoretical values of the bending moments. The bending moments of different cross –sectional areas have different formulae of calculating the moments. This experiment will use a rectangular shaped cross-sectional beam for easier working and better understanding. The main objective of this simple experiment is to determine the bending of a beam that is simply supported that is subjected to the various loads that are arranged as shown below. The experiment will also help to compare the measured or the experimental values of bending moments with the values calculated using the theoretical approach. In this experiment, a simply supported beam, a spring load gauge and weights placed in weight hangers are used. A level spirit gauge is also used to check whether the beam is properly aligned. A simply supported beam is pivoted at a point and then loaded with different weights. A spring load gauge is connected to the beam at the pivot. The apparatus is as shown in the diagram. The span of the beam (L) and the distance to the bending moment position (x) from the left support are to be measured, and the values are recorded. The vertical distance between the pivot point and the spring load gauge (y) is to be measured too, and the value is recorded. The beam is then leveled by adjusting the horizontal spring load gauge and checked with a spirit level. Load hangers are then applied to the beam at the positions shown in the above diagram, and the positions are then recorded. Masses of 0.5 kilograms or 1.0 kilogram are added to the load hangers as shown in the table below. The beam is then leveled by adjusting the horizontal spring load gauge and checked with a spirit level. The reading from the horizontal spring load gauge is recorded. Remove all the loads from the hangers and repeat the steps from measuring and
