Bending of Beam Lab Report Essay

There are also some assumptions made with respect to this theory. The results of the experiment came out just as they were expected. It can be also observable that some properties of beams can also vary from one to another due to the type difference such as ductility, stiffness and so on. 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. Lower the gauge so that its small hand is at about 10 and set the gauge to zero by twisting its outer ring. Initial Clearance in New Clearance in Experimental Deflection in Theoretical Deflection in 2.

For aluminium the percentage was at 65 % to 70 % For steel the percentage was at 60 % to 75 % It is because the graph it makes from the parallel line and the theory we use the calculations 3. In order to conduct this experiment and to investigate the variation of deflection of a simply supported beam, an apparatus that contains two support points is used. If the steel data are isolated, the following graph is obtained. A clock gauge is positioned in the middle of the beam to measure the deflection. We also observed the relationship between load and deformation. Deformasi pada balok dapat dijelaskan berdasarkan defleksi balok dari posisi sebelumnya mengalami pembebanan.

Mild steel is clamped at one end and the other end left free. If the maximum deflection that the beam can resist were not taken into consideration in the design process, there would be some serious failures in structures that can lead to some serious outcomes. This equation is also appropriate because the configuration of the experiment just differs the m values. Langkah 5 Setelah konstruksi jembatan sudah jadi, beri material baja karbon. So recording the procedure in our lab book is important. Depending on the triggering accidental event, initial failure might occur in the vertical plane through the bridge axis or in transverse direction.

Initial Clearance in New Clearance in Experimental Deflection in Theoretical Deflection in 2. The relationships between these variables and. To begin with, a brief introduction on elasticity is presented, including some related definition and formulae. It also aims to make observations on the beam mode of failure. Our primary aim was to demonstrate the different techniques needed to isolate biosynthetic auxotrophic mutants using chemical, physical and transposon mutagenesis.

The specimen was then rotated after undoing the top chuck. The second portion of the experiment used knownâ€¦ 2654 Words 11 Pages Spring 2013 Lab Report Experiment 3 Bending of Beams Section ThTh12 Group 1 Ã–mer Ege Ã‡alÄ±ÅŸkan Serhat Karakuz Noyan UÄŸur Renda Turgut Soydan 20. At the beginning of the semester we were divided into several groups and were assigned an unknown of which we were tasked with identifying. If the curve has no linear region, a secant line is fitted to the curve to determine slope. Flexural testing is commonly used on brittle materials such as ceramics, stone, masonry and glasses. Following is the free body diagram of the beam attached to the apparatus and under the load at two different points. Free body diagram of the apparatus is shown below.

Therefore, the reading of the height might be different from time to other, so, the calculation of deflection is different from the theoretical. In the morning and evening its shadow strikes the pot superficially, while; it midday, around 12. These predictions were both inferred from common sense and from the theory itself. Objective: The objective of this experiment is to demonstrate the bending of a bean when loaded at the center of its length and examine its deflection when positioned in two different ways, when the flat side of the beam is support and when the thin side is supported. Stand a mirror in front of one eyepiece so that it throws an image of the sun on to the opposite wall of the room. The data showed the same trend with the theory, but lacked precision.

A simply supported beam is fixed on two ends. The steps described in Case I was repeated and data was recorded. The change in clearance of every load step was measured and data was recorded. Cantilever beam When a beam is secured on one end and is freely hanging, it is regarded as a cantilever beam. The first portion of the experiment seemed to be a practice 10 fold serial dilution using the chemical bromophenol blue, and was treated as a quantitative experiment. Although Figure B and Figure C seem similar at a first glance, a closer look reveals that the slopes of the graphs are different.

Words: 1490 - Pages: 6. Equation 2 is used to calculate the value of flexural strength. 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. Now load is increased as per the table and the deflection of beam is noted. In addition, try to find linear relationship between the load applied and the deflection of the beam and comparing the experimental deflection with the theoretical deflection. From this, the shear center was established by determining the intersection point. By this experiment, the relation between the deflection and beam thickness can also be observed and proved.

Langkah 2 Setelah mengklik Solidworks Toolbox, kemudian akan muncul tool Structural Steel dan Beam Calculator. There is a requirement for this theory to be applied on a beam. Submitted By turntable24 Words 410 Pages 2 Assignment 9 â€” Beam Deflection Experiment Report 1 L mm L3 680 314432000 700 343000000 800 512000000 900 729000000 1000 1E+09 1100 1. The direction of the deflection highly depends on the direction of load applied. Little different between the values is due to human error which cannot be minimize due to the human capabilities limitation. The change in clearance of every load step was measured and data was recorded.

A cantilever beam is supported on one end only and must be built into the wall that supports it. The frame was tapped to reduce friction and loads applied in 100 g increments upto 500 g on the end of the cord. This technique requires specialised fixtures and precision displacement measurement coupled with advanced flexural testing software. Where P is the applied force, L is the length of beam, E is the modulus of elasticity of aluminum, and I is the moment of Inertia. Apparatus The first requirement is a controllable loading machine that allows addition of the load.
