A bending moment is an internal force that is induced in a restrained structural element when external forces are applied.
Figure 1 bending moment apparatus Figure 2 free body diagram In this experiment load of different magnitude will applied on beam at the same place and bending moment will be calculated using the following formula.
Thus, the relationship between the stress, bending moment and the load can be determined. Torsional moment or Torque, T An external torque tends to twist a circular member about its longitudinal axis. The bending moment in Case 1 is higher than Case 2 because the P applied in Case 1 is at the center of the beam.
Theory Beams A structural element which is designed and used to bear high load of structure and other external load is called beam. The percentage error is low and it proves that the experiment was carried out carefully. When analysing an entire element, it is sensible to calculate moments at both ends of the element, at the beginning, centre and end of any uniformly distributed loads, and directly underneath any point loads.
Following tables and graphs show the result of the experiment. Introduction and Background Theory Definition of a Beam Members that are slender and support loadings that are applied perpendicular to their longitudinal axis are called beams. The dynamometers were zeroed and horizontal beam alignment was carried out when placing the weights.
Next, we have the fix the load hangar in between the beam. Experimental Procedures and Setup: The stress and strain relationship is linear and elastic. The experiment was carried out by setting up two edges support on the base of two structural frames with an equal separation distance on both ends.
In these diagrams, the abscissa horizontal axis indicates the position of the section along the beam, and the ordinate vertical axis represent the values of the shearing force and bending moment at any section along the length of the beam.
The two edge supports were set up on the base of the structural test frame at a distance of mm from edge to edge. Reading results for load vs bending moment Discussion From the table above, it can be noted that the load is directly proportional to the bending moment.
The change in clearance of every load step was measured and data was recorded. Measure the length of L and a once again after different load is applied on the beam.
Furthermore, there is a slight moving, vibrating or oscillating of the load while recording the shear force. The following experiments were carried out: For example, a simply supported beam is pinned at one end and roller-supported at the other, a cantilevered beam is fixed at one end and free at the other, and an overhanging beam has one or both of its ends freely extended over the supports.
One of the possible reasons is that the position of load applied might not be exactly at the center middlethe load might slightly away from the center and due to this reason, the dynamometer gives reading of both shear force and bending moment at the particular position.
From the experiment, it is found that decreasing the distance from a reference position need lesser bending moment. Repeat to obtain accuracy and ask different members of the group to perform the same experiment.
First, turn the dial gauge to zero and then the digital recorder to zero as well. Frank Durka and Hassan al Nageim, Conclusion The conclusion to this report is that the deflection and load are directly proportional and deflection increases as greater load is placed on the beam.
It is a good sign as it shows the laboratory experiment was carried out efficiently with few errors.

8 Summary and Conclusion parameters that influence on the joint structural behaviour were considered and the main conclusions are: The prediction of the bending moment. Conclusion: As mentioned before, with this experiment we concluded that the deflection of a beam is different depending on its position.
We also concluded that when the beam is positioned with its thin side on the supports it is able to carry more load than when it is positioned with its flat side on the supports. Conclusion From this experiment we were able to determine how shear force from ENGR at University of Ontario Institute of Technology%(8).
