Bending of Beam Lab Report Paper Where P is the applied force, L is the length of beam, E is the modulus of elasticity f aluminum, and I is the moment of Inertia. For a beam of rectangular cross section, say of width w and thickness t, the same mid spam deflection of the centrally loaded beam when the flat side is supported, then be compared to that when the thin side is supported. The moment of inertia for the respective situations are given by: II = WTG/12 and 12 = wet/12 It could be readily verified that the later situation offers less deflection under the same load. 2. Introduction: In this experiment we tested the deflection of a beam when it is placed with its widest and shortest side of its cross section on the supports. In order to examine he deflection of the beam, we applied the load at the center of its length. In addition, observing the deflection on the beam, we wanted to observe if the behavior of the deflection would be different when the position of the beam changed. After conduction the experiment we conclude that when the beam is positioned with its widest side on the supports, deflection happens faster and as more load is applied the deflection increases. . Experimental Procedures and Setup: Case l: The dimensions of the beam was measured and the cross sectional area and the moment of inertia were calculated. Next, the beam was placed on the tan such that the widest side of the cross section is on the supporters, and the scale was reset. The clearance between the middle of the beam and another beam placed on the top of the stand was measured. The beam was loaded the middlemen in 2. 745 lbs. Increments up to 6. 745 lbs. The change in clearance of every load step was measured and data was recorded.

Source of Error: There are some errors between the theoretical and the experimental deflection. This error might have happened because of the inaccuracy in measuring the length between the beam and the ground, which happens because of not measuring the length perpendicular to the beam itself. Therefore, the reading of the height might be different from time to other, so, the calculation of deflection is different from the theoretical. . 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. This is due to the fact the beams inertia change as the position changes. When the beam is placed on its flat side its inertia is less than when sectioned on its thin side where the inertia is bigger. This means that because the flat side has less inertia there will be less resistance in changing its position, so it will deflect more. Because the thin side has more inertia, it will have more resistance in changing its state.
