Bending Lab Report Final Essays
Bending Lab Report Final Essays Bending Lab Report Final Paper Bending Lab Report Final Paper The second part of the lab will focus on using the ISM 04 Beam Apparatus to determine the deflection f point-loaded simply-supported beams made of steel, brass or aluminum. Using the deflection measurements, an examination of the relationship between deflection and material properties will be shown along with a comparison of the materials based on their strengths and deflections, both theoretical and experimental. The last objective of this laboratory is to verify the theory of pure bending using the SMASH Beam Apparatus. Introduction Engineers use beams to support loads over a span length. These beams are structural members that are only loaded non-axially causing them to be objected to bending. A piece is said to be in bending if the forces act on a piece of material in such a way that they tend to induce compressive stresses over one part of a cross section of the piece and tensile stresses over the remaining part (Ref. 1). This definition of bending is illustrated below in Figure 1. Figure 1 Bending on a Cross Section 5 It can be seen from Figure 1 that the compressive force, C, and the tensile force, T, acting on the member are equal in magnitude because of equilibrium. Therefore, the compressive force and the tensile force form a force couple whose moment is equal to either the tensile force multiplied by the moment arm or the compressive force multiplied by the moment arm. The moment arm is denoted, e, in Figure 1. Figure 2 Bending Action caused by Transverse Loads Figure 2, shown above, is an illustration of bending action in a beam acted upon by transverse loads. Bending may be accompanied by direct stress, transverse shear or torsions shear, however for convenience; bending stresses may be considered separately (Ref. 1). In order to separate the stresses it is assumed that the loads are applied in the following manner: loads act in a plane of symmetry, o twisting occurs, deflections are parallel to the plane of the loads, and no longitudinal forces are induced by the loads or by the supports (Ref. 1). A beam or part of a beam that is only acted on by the bending stresses is said to be in a condition of pure bending. However for many circumstances bending is accompany by transverse shear. The term flexure is used to refer to bending tests of beams subjected to transverse loading (Ref. ). A visual illustration of the transverse shear and bending moment can 6 be seen in the shear and bending moment diagrams of the beam. It is important o note that in a symmetrical 2-point loading scenario, the center portion of the beam will be in a condition of pure bending as such the bending stresses may be considered separately. Deflection of a beam is the displacement of a point on the neutral surface of a beam fr om its original position under the action of applied loads (Ref. 1). Before the proportional limit of the material, the deflection, A, can be calculated using the moment of inertia, modulus of elasticity along with other section properties that will depend on the given situation imposed on the beam. The position of the load, the type of load applied on the beam, and the Engel of beam are examples of section properties that depend on the situation. The deflection equations for two common cases are listed below in equations (1) and (2). Case 1: Center deflection of a simple beam with freely supported ends and concentrated load, P, at the mid-span (Ref. ). Equation (1) where: A = deflection, (mm) P = load, (N) L = length of beam, (mm) E = modulus of elasticity (N/mm) = moment of inertia of section about the neutral axis, (mm) 7 Case 2: Center deflection of a simple beam with concentrated loads, each equal to P, at third points of span (Ref. 1). Equation (2) P load, (N) moment of inertia of section about the neutral axis, (mm) Deflection is a measure of o verall stiffness of a given beam and can be seen to be a function of the stiffness of the material and proportions of the piece (Ref. 1). Deflection measurements give the engineer a way to calculate the modulus of elasticity for a material in flexure. The stiffness of a given material is calculated using the following equation: Equation (3) p = load, (N) Stiffness (N/m) 8 A beam may fail in any of the following ways: A beam may fail by yielding of extreme fibers, in long span beams compression fivers act like those of a column ND fail by buckling, in webbed members excessive shear stress may occur and stress concentrations may build up in parts of beam adjacent to bearing blocks (Ref. 1).

Good or Bad Performance for Cities Essay Example | Topics and Well Written Essays - 750 words
Good or Bad Performance for Cities - Essay Example In several studies, graffiti was found to have the following advantages to the cities: (1) it revitalizes the city through ââ¬Å"controlled graffitiâ⬠; (2) it is a form of community beautification by spicing up urban blight and (3) it educates the public through disseminating relevant social issues. On the other hand, graffiti has still been viewed as a form of vandalism and a crime in many societies. The City of Calgary, for example, penalizes those caught doing graffiti with a $5000 fine. It is viewed as a waste of time and resources as the city would eventually resort to cleaning and removing them. The costs of removing them are tremendous and take a financial toll to the government. The Journal Live news of graffiti report ââ¬Å"unwelcome art attacks cost à £1m a year MORE than a million pounds is spent every year cleaning up graffiti in the North-East". In addition, prison sentences were handed to members of a gang who work on making graffiti and were found to have destr oyed ââ¬Å"hundreds of buildings and railway bridges in their distinctive tags over eight months, giving transport operators a huge clean-up bill amounting to à £140,000â⬠. The actions of graffiti artists are evaluated according to their specific objectives or purpose for doing their art form. Most governments have recognized the evolution of graffiti art as continuously transforming. Stowers (1997) averred that ââ¬Å"whether or not all of the public agrees that graffiti art is good, bad, or extremely valuable is a different discussion.

Maureen Frye Essay Example for Free
Maureen Frye Essay Marureen Frye made numerous mistakes in trying to implement her plan, a plan that was going to directly affect the salespeople of Quaker Steel Company as well as the District Sales Managers (DSMs), among other departments in the company. Her major mistake was sending a short-descriptive memo to the sales representatives. Why was this a major mistake? For one, Frye is trying to change the way the sales people allocate their time between big and small accounts, and yet she has not spend enough time in the field and with these salespeople. Although her simulations to optimize sales efforts might be correct, they are based on cold numbers and computations, sitting behind a computer, without taking into account the human factor that goes into those sales efforts. She does not have a feel for how they operate, where does their current success come from, what do they think and feel about how they are doing their job, and above what do they think it can be improved. Not only did Frye ignore the salespeople but she did not make good use of the relationship she thought she had with the DSMs. In fact, she had discussed her project with the Chicago DSM and he had seems to like to idea, with indicates that if more effort was put to introducing her plan to the other DSMs, using her good relationships with them, they could possibly perceive the idea well too idea of using the middle man. If she had no time to spend on the field and get to know the salespeople better, she made the mistake of not taking advantage of the relationship between the DSMs and the salespeople. Due to the hierarchical level of the DSMs, she is probably closer to them. As it is mentioned in the article, the DSMs leave a lot of free space to the salespeople which means that they are used to making their own decisions. This fact shows that the DSMs and the Salespeople have a special communication to understating each-other and to get the work done well. Thus, if a new project needs to be implemented, the DSMs are the most probable people to get through the salespeople and having them on board about this project is significantly important. This powerful link should have been taken advantage by Frye. Not having considered the above-mentioned steps, thus working in person with the salespeople or/and lobbying with the DSMs, Frye should have at least used the power of her superiors, Israel and Bethancourt, not only byà approving it but also as means of enforcement. For example, have them sign the memo she sent or give a direct order to the DSMs for its application. However, needs to be emphasized that this solution used on its own, is a last resort one just because she didnââ¬â¢t make use of the other options. This option would definitely be interpreted as a scare tactic, however it might have worked. As a manager or as the leader of her project, Frye first needs to find the authority from within and then also use the power given to her from her bosses. This option could be best used in collaboration with the previous options.

Isaac Newton :: Biography, Science
Isaac Newton was a brilliant scientist who discovered many important things. The sources for this report are Encyclopedia" and the book "Isaac Newton: The Greatest Scientist of All Time" by Margaret Jean Anderson. Sir Isaac Newton was born on December 25, 1642 (according to the Julian calendar which was in use then; the date was January 4, 1643, according to the Gregorian calendar in use today), at Woolsthorpe, near Grantham in Lincolnshire. His widowed mother remarried when he was three years old, leaving him in care of his feeble grandmother. Eventually his mother was persuaded to send him to grammar school in Grantham. Later, in the summer of 1661, he was sent to Trinity College, at the University of Cambridge. Isaac Newton received his bachelor's degree in 1665. After an intermission of nearly two years he returned to Trinity College, which elected him to a fellowship in 1667. Isaac Newton received his master's degree in 1668. Newton ignored much of the established curriculum of the university to pursue his own interests: mathematics and natural philosophy. Proceeding entirely on his own, he investigated the latest developments in mathematics and the new natural philosophy that treated nature as a complicated machine. Almost immediately, he made fundamental discoveries that were instrumental in his career in science. Sir Isaac Newton, the English mathematician and physicist, is considered to be one of the greatest scientists in history. He made important contributions to many fields of science. His discoveries and theories laid the foundation for much of the progress in science and math since his

P-ISM
When writing a short observe, pen and paper are nevertheless maximum herbals to use. The five pen technology with virtual pen and paper makes it possible to get a digital reproduction of handwritten facts and have it ship to virtual devices through BluetoothP-ISM (Pen Style Personal Networking Gadget) that is nothing but the new discovery that's developed by means of the Nec Co-operation in 2003 . It's far truly a new invention in the computer and it is related to communique area. Honestly, this may have a remarkable effect on the pc discipline. In this tool, you will locate Bluetooth as the main interconnecting tool between extraordinary peripherals.INTRODUCTIONLaptop impacts our lives in a far larger manner then most of us may have an idea. It has grown to be a compulsory requirement in most professions with a view to use pc software. Modern computer systems which can be primarily based on integrated circuits are small enough to fit into mobile gadgets, however, imagine having a computer a good way to suit into a pen.Imagine a global wherein everybody can use modern IT without being a professional. P-ISM is a system gadget including five functions: it includes a CPU for processing, it also used as a conversation pen, it carries a very small projector within it, and also it has a digital camera scanner and a battery with it. P-ISMs are linked to each other via short-range Wi-Fi generation. The P-ISM (Pen-fashion personal Networking machine bundle) is best a prototype underneath growing level by NEC employer. In 2003, Geneva held the ITU telecom phrase exhibition which exhibited a conceptual $30,000 prototype of a P-ISM designed by means of the Tokyo-based totally NEC employer.A PC that uses an electronic pen (called a stylus) as opposed to a console for input. Pen PCs for the most part require unique working frameworks that help penmanship acknowledgment with the goal that clients can compose on the screen or on a tablet as opposed to writing on a console. Most pen PCs are hand-held gadgets, which are too little for a full-estimate console.WORKING PROCESSThe P-ISM (Pen-style personal Networking system gadget) consists of a gadget of five pens that everyone has unique capabilities, Figure 1: Working of P-ISM? CPU penCPU capability is dead by mistreatment the pen itself. ââ¬Å"P-ISMâ⬠is additionally referred to as computing engine Processors used within the pen is that the twin-core processor and it's miles labored on the premise of home windows OS.? Communication penP-ISM uses Wireless Bluetooth technology for the communication and transfers the information to a different system. P-ISM additionally also will create a connection to with any cellular device and also it can use the Wi-Fi technology. ? Virtual keyboardP-ism provides associate degree integral virtual optical maser keyboard that may be a new widget. The operating of the P-ISM is that it emits the optical maser beams on the table surface that forms a keyboard On this specific keyboard, this can be done by a 3D IR sensing element technology with optical maser technology to induce a full-size keyboard. ? Led ProjectorThe pen contains an Led projector within it. So it can project an led monitor with the size of A4 and the resolution of the screen is approximately of 1024*768. The monitor projected by the P-ISM gave more clarity for the projection and a gave a good picture to the viewer.? Digital CameraWe had a photographic camera within the form of a pen. It is helpful in video, Videoconferencing; merely it's known as a net cam. It's additionally connected to different devices through Bluetooth. The key advantage it's little that is well transportable. It's a 360- Degree communication Device. We've seen video phones many times in movies.Advantages of P-ISMWhat makes the P-ISM totally different from all of the prevailing elements is that its form likes pens. Pens are quite common objects that we supply around on everyday basis; by carrying simply four pens you'll produce a laptop. So, its transportable and may be carried simply.As the pen is a smaller amount visible and it's easier to require it out with you, the scale and weight are plenty less and it will probably priceless because it can use less material.P-ISM adopts Bluetooth technology for informatio n transfer that may be a wireless technology.Disadvantages of P-ISMThe P-ISM is formed from five loose pens which are able to move around with any amendment within the movement of the area. in an exceedingly train journey, there's tons of movement which is able to shake the pens around and shake the projection of the keyboard and screen. So, this can't be as stable and economical as a portable computer.Also, these pens area unit terribly little and fragile so that they are broken simply whereas handling them or carrying them around. One pen itself prices quite a striated muscle thus you can't risk damaging or losing them.ConclusionThe specialized gadgets are getting to be noticeably littler and conservative. This is just a case of the beginning of this new innovation. We can expect all the more such advancements later on; it appears that data terminals are boundlessly getting littler P-ISM.

The Things They Carried By Tim O Brien - 2000 Words
Disorder, destruction, and death became the description for the Vietnam War. This war affected the soldiers more than any other war, even before they would ever go. As American soldiers left to fight the disorderly and deathly war, Americans were going through one of the most confusing time periods in American history: families being split by the draft, the fear of the communist domino theory, and the search for a new soldier to find oneself in the midst of all the chaos. The invention of the television affected American citizens more than any other war. The television became popular to American households in the 1950s, so when the Vietnam war began, anybody who owned a television gained the ability to stay updated and informed on the progress of the war. The Vietnam War was not just a time of fear, confusion, and change for the American soldier, but also for the American citizens back home, fearing what could happen to their families and their country.
