The suspension takes a hit when a car goes over a bump or into a pothole. The process is repeated again and again for different weight. Internal stresses bending stress develop in the beam. The hammer and the… 2654 Words 11 Pages 2013 Lab Report Experiment 3 Bending of Beams Section ThTh12 Group 1 Ömer Ege Çalışkan Serhat Karakuz Noyan Uğur Renda Turgut Soydan 20. 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. If we increase the loads, deformation will also decrease. There was a second test performed in this investigation demonstrating the influence the 2nd moment of area, also known as the second moment of inertia, had on the load carrying capacity of the beam.
Initial Clearance in New Clearance in Experimental Deflection in Theoretical Deflection in 2. 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. Change is shape of the body is called deflection and change in the dimensions is called strain. Some different types of beam are describe below Simple supported beam Simple supported beam is one which has support at its both ends but does not face any moving resistance Fixed beam Like simple supported beam fixed also has support at its both ends but fixed beam has moving resistance Over hanging beam Over hanging beam also have support at both of its ends like simple supported beam but one of its ends is free and extended further from the end support Double over hanging beam Double over hanging beam is just like over hanging beam, the only difference is that its both ends are extended beyond the end support Continuous beam Continuous beam is one which has large length and it is supported by more than two supports Cantilever beam Cantilever beam is one which has its one end fixed and other end is free to vibrate Trussed beam Trussed beam is a special type of beam which has increased strength due to additional rods and cables in beam In this experiment only two types of beam will be discussed one is simple supported beam and other is cantilever beam. Words: 1104 - Pages: 5. The beams analyzed will have three configurations: an I-Beam type where the steel flange width, bf, is greater than the timber web thickness, tw; a Box Beam configuration where the steel flange width is equal to the timber web thickness; and an Architectural Beam style where the steel flange width is less than the timber web thickness and the steel flanges are totally encapsulated within the timber web. This load shows the strength of any beam with respect of the load applied on it.
Displacements from the initial axes are called bending or flexural deflections. . The strain gages are connected into a power supply which is adjusted to 10volts using the array of electrical terminal, and connect a multimeter to the S+ and S- terminals to read the strain. . To measure deflections and strains in a simply supported steel beam. We also observed the relationship between load and deformation. Typically, if one were to place a weight towards the free end of a cantilever, some bending, or flexion, would be expected.
. The deflection of beam is noted using the digital dial. Before testing each steel beam, the deflection gage is set at zero 0 value. 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. Table 2 Test Specimen Properties Note: The length for the two beams was held constant for Experiment One. Initial Clearance in New Clearance in Experimental Deflection in Theoretical Deflection 2. An experiment is a way of investigation a cause and effect relationship between independent variable and dependent variable.
The moon and stars cannot be observed in this way because the light coming from them is too weak. The second part of the experiment had one point load applied at different lengths. Dynamic Systems and Controls Laboratory Experiment 2: Fundamental Frequency of a Beam Due: October 9th, 2015 Submitted: October 9th, 2015 Table of Contents Abstract 2 List of Symbols and Units 3 Theory 4 Procedure and Experimental Setup 8 Sample Calculation 9 Error Analysis 12 Results 13 Discussion and Conclusion 16 References 18 Appendix 19 Abstract The experimental analysis of rotating equipment and the fundamental frequency of an attached beam was achieved by attaching a motor to a simply supported beam with adjustable weights. . Data of experiments was written in their respective tables. It is very important to calculate the permissible load of all the beams in order to get a safe structure. Displacements from the initial axes are called bending or flexural deflections.
Front Cover The Vibrating Spring - Experiment 02 Many objects in the real world have a frequency at which they vibrate. To begin with, a brief introduction on elasticity is presented, including some related definition and formulae. Nonetheless, Experiment 1 proved effective in determining fairly accurate values for structural stiffness. . Words: 1490 - Pages: 6. .
Words: 794 - Pages: 4. In order to examine the deflection of the beam, we applied the load at the center of its length. . To compare the analytical and experimental values of strains in the beam. The theoretical value of stiffness was also calculated using equation 7. From this, the researchers are able to observe behaviour and be able to see cause and affect relationship between. The length of the battery will be determined from the time the head lamp was turned on to when the light quit shining.
Using the inverse of the slope from the linear trend lines of aluminum and steel, experimental stiffness was calculated. . The beam was loaded the mid-length in 2. . Words: 1585 - Pages: 7.
Words: 7410 - Pages: 30. The steps described in Case I was repeated and data was recorded. The following equation also shows that the larger the structural stiffness is, the less deflection a beam will have. . .
Dimensionally, the structural stiffness of the beam will also increase with a larger width and larger height and decrease with a longer length. Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. This means that because the flat side has less inertia there will be less resistance in changing its position, so it will deflect more. Langkah 5 Setelah konstruksi jembatan sudah jadi, beri material baja karbon. The theoretical deflection, theoretical stiffness, average, and standard deviation were calculated for each mass using equations 1, 7, 8, and, 9, respectively. 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.
