A bending of beam experiment is a common laboratory experiment in which the deformation of a beam under load is studied. The goal of this experiment is to understand how the beam behaves under different loads and how the various physical properties of the beam, such as its material properties and cross-sectional shape, affect its response to these loads.

The experiment is typically set up as follows: a beam is placed on two supports, with one end of the beam clamped to a fixed support and the other end resting on a moveable support. A load is then applied to the beam at various points along its length, and the deformation of the beam is measured using a displacement sensor or a strain gauge.

There are several factors that can affect the bending of a beam. These include the material properties of the beam, such as its Young's modulus (a measure of its stiffness) and Poisson's ratio (a measure of its lateral strain under load); the cross-sectional shape of the beam, such as its width, height, and shape; and the type and magnitude of the load applied to the beam.

In the bending of beam experiment, the results of the measurements are typically plotted as a graph showing the relationship between the applied load and the beam's deformation. This graph can be used to determine the beam's stiffness and its ability to resist bending under different loads.

One of the key findings from the bending of beam experiment is the relationship between the applied load and the beam's deformation, known as the beam's bending moment. This relationship is described by the beam's bending moment equation, which is a mathematical expression that relates the applied load, the beam's cross-sectional shape, and its material properties.

In conclusion, the bending of beam experiment is a useful tool for studying the deformation of beams under load and understanding how various factors, such as material properties and cross-sectional shape, affect the beam's response to these loads. This knowledge can be used to design stronger, more efficient beams for a variety of engineering applications.

## (DOC) Lab Report for Beam Bending (1)

There are different beam theories postulated up to now to describe the behaviour of beams under loading. Connect the strain gauges to the strain meter. Then 2N more is applied, and total load achieved to 4N and the displacement value is read. Each material was positioned upright as well as flat to test different methods for efficiency. Because the thin side has more inertia, it will have more resistance in changing its state. First simply supported beam which have supports at its both ends, second is overhanging beam which have length extended over its supports, third is overhanging beam which have more than two supports and fourth is cantilever beam which fixed only at one end and other end is free.

This is due to the fact that the second moment of inertia of beam is much more than that of plank due to which it deflection is much less than that of plank. Initially the displacement value of aluminum beam is measured with the very same procedure as in steel beams. When load is applied to the beam crakes may lead to quick failure of beam much before it is expected. Title: Deflection and Bending of Beam 2. The experiment also aims to show how the material property affects maximum deflection. The resulting dial gauge reading is recorded.

A suitable load is placed on the load hangar. Beams provide support to the structures by resisting against the forces which are applied on that structure. TABLE II P lbs. The values in the displacement gage are read after each 2N weight addition. The width and depth of the beam specimen is measured and the readings is recorded.

The above experiment is repeated to obtain another set of reading. A dial gauge with 0. It is observed that the deflection of the beam changes linearly with the load and as the beam thickness increases, the beam deflection decreases. Figure B : Max Deflections of Different Materials Under Various Loads Figure B : Max Deflections of Different Materials Under Various Loads Using the tabulated data, the following graph can be obtained to show how each sample deflected under various loads. Elasticity of Beam 4.

Abstract In this experiment, a simply supported beam is used and the variations of deflection of a simply supported beam with load, beam thickness and material are investigated. The results of the experiment came out just as they were expected. Since the moment of inertia depends and varies with h3, it is enough to observe the change in slope with varying h3. Length of Beam 3. Experimental Procedures and Setup: Case I: The dimensions of the beam was measured and the cross sectional area and the moment of inertia were calculated.

The dial gauge is positioned at the mid-span of the beam to measure the resulting deflection. Lastly, students continued to repeat measuring the minimum and maximum for each of the ten weights and recorded all the values in the excel seed file. As the elastic modulus increases, it is harder to deflect the beam. The beam specimen is placed on the knife-edged supports. The tables will demonstrate the experimental and theoretical deflection for each case. 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.

It defines the relationship between stress and strain in a material. The distance between the two supports is equal to the span of beam used. The steps described in Case I was repeated and data was recorded. Comparing the deflection of both plank and beam shows that to reach the highest value of 13 mm deflection plank takes 4 KN of load whereas beam takes about 9 KN of load which shows that beam has much more resistance against deflection as compared to plank. 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 placing the 3 mm steel beam on the experiment apparatus and the gage is set to zero value, the beam is subjected to some loading right in the middle section. Treating knots in a beam as a system of two ellipses that change the local bending stiffness has been shown to improve the fit of a theoretical beam displacement function to edge-line deflection data extracted from digital imagery of experimentally loaded beams. A pair of pinned support. Step 8 and 9 is repeated for a few more load increments. We also observed the relationship between load and deformation. Type of Beam i.

Moment of inertia of beam is its shape dependent property which shows the beam ability to resist bending moment applied on it. Bending Moment Analysis 5 2. Experimental Procedures Experiments were conducted on three different materials: pine, Douglas fir, and steel. The test is repeated other beams. Depending on the results of the experiment, it is observed that the measured deflection values under different loads and for different materials overlap the Euler-Bernoulli Beam Theory. The free body diagram for a left-hand portion of the beam.
