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 Deflection lab report beam itself.
We can see from the data that when load are added along the length of the wood it tended to bend more than when adding weight to it width. If we increase the loads, deformation will also decrease.
According to Raymond Aurelius Higgins there is a great different in values of elastic modulus, which shows that there are some errors in the experiment and those errors needed to discussed in order to get accurate values for elastic modulus. It can also be concluded that the experimental elastic modulus of same material is different in every case and really depends on the beam type, shape and loading place.
From this experiment we learned that when when a Deflection lab report will be placed with the wide side on supports it will show les deflection and is more efficient to use.
From these experiments it can be concluded that the deflection in a beam under a constant force depends on its type, shape, material and point of application of force. 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.
Following tables and graphs show the result of the experiment. Error in the beam experiments could be form two sources one in apparatus error and second is human error.
Steel graph for cantilever show very abnormal values of displacement.
From this it can be concluded that the second moment of inertia is property of beam which resist the bending or deflection of beam. The beam was turned around in such way that the shortest side of the cross section is on the support.
It also has liner response between load and displacement but its value of displacement for the given load is more than that of the brass which shows that aluminum is more ductile than that of brass as explained by B.
Now each graph will be discussed here. Because the thin side has more inertia, it will have more resistance in changing its state. The dimensions of the beam was measured Deflection lab report the cross sectional area and the moment of inertia were calculated.
There are some errors between the theoretical and the experimental deflection. Next, the beam was placed on the stand such that the widest side of the cross section is on the supporters, and the scale was reset. The beam was loaded the mid-length in 2. Instrument error includes inaccurate dial gauge, apparatus not balance on horizontal surface or beam is already deformed.
A personal error includes observation and calculation with wrong method or lack of experience in experimentation.
The change in clearance of every load step was measured and data was recorded. According to the table the value of elastic modulus for brass is about Values of the displacement of bam for brass is greater than steel because according To Kenneth G.
Personal error can find out by repeating the experiment with some experience person and can be removed by practices. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.
As mentioned before, with this experiment we concluded that the deflection of a beam is different depending on its position.Vice versa, when the load is removed, the deflection decreases as well, it can also be noted that the theoretical deflection is higher than the experimental deflection.
This can be due to the errors committed during the lab work as well as the effect of limiting factors such as inaccuracy of readings for more than two decimal places. R. Ehrgott 2/11 01/28/01 I.
OBJECTIVES To observe, evaluate and report on the load deflection relationship of a simply supported beam and a cantilever beam.
Essays - largest database of quality sample essays and research papers on Deflection Of Beam Lab Report. 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.
We will write a custom essay sample on Bending of Beam Lab Report specifically for you. Deflection of Beam Lab Report Aim Aim of this lab work is to study and understand the deflection of beam made of different materials Objective Study and understand different types of beams Study and understand the permissible load of different beams.
Now you Leah Perez Page 3 of 20 9/21/10 Lab Report: Lab #3 Beam Bending Experiment will load the beam with weights in 25 lb increments, starting at 25 lbs and ending at lbs or until you reach in deflection/5(3).Download
