the three equations of equilibrium. 2: Hooke’s Law, Poisson’s Ratio and Modulus of rigidity. Hooke’s law, Poisson’s ratio and shear modulus (modulus of rigidity) all share a common bond. They are considered to be individually the same for a specific material. hooke’s law is formulated as F=kx; Poisson’s ratio is formulated as = (lateral strain / axial strain) and shear modulus is formulated as G= E/(2(1+" " )). 3: polar moment of inertia and angle of twist. Determinate systems: (ISO-STATIC)
Simple Stress and Strain The strength of materials are expressed from the point of view of machine designer. A machine designer needs to know the properties of different materials so that he can select the most suitable material for each part of a machine. A machine designer uses his information of stress to make sure that the stress is reasonable and that each part of the machine is sufficiently strong. Strength of materials is the scientific area of applied mechanics for the study of the strength
5.1 Introduction Structurally, the Salt Range is the result of tectonic forces imposed during the lateral phases of the Himalayan orogeny in the late Cenozoic time; the occurrence of the thick, incompetent Salt Range formation at the base of the sedimentary sequence has strongly influenced the structure. 5.2 GENERAL STRUCTURES OF THE PAIL-BAHDRAR AREA Structural features were essentially the result of gravitative flow process (a tectonic diaprisim) involving the subsurface flow of highly incompetent
Writing 1 I begin my hike in comfortable clothes, a camelbak, flashlight and my ticket to view the caves. The first thing I see is the large rockslide above the visitor’s center. The rockslide is called talus slop. A talus slope describes a type of rockslide that is a loose debris piles. Talus slopes have mild to moderate rockslides as rocks slide down the pile. I was surprised when one such rock hit my head dead center. Facing the American Fork Canyon in the Wasatch Mountains of Utah, USA I see
pressure for a person in such a position to succeed. If they do not, then it is their job on the line. Therefore, they deserve to receive a large sum of money for the work that they do. It is the only way to compensate these employees for the tremendous strain that their job puts on them. It is essential that the employees get paid the amount of money that they deserve. Pay Should Reflect Performance When CEOs are being given big paychecks, they are expected to perform at a high level. There success is
Since the introduction of the fog/combination firefighting nozzle by Dr. Oyston Charles in the 1960 's, the discussion between the traditional smooth bore nozzle vs. fog/combination nozzle for fire attack has been ongoing and heated at times. My research has informed me that the debate between the smooth bore nozzle and fog nozzle has always and will continue to be openly controversial, particularly over the last two decades as the fire service has taken a deeper interest in firefighter safety and
Reginald Mouton 11/16/2016 Youngblood Defensive Argument Essay Some people may say they don’t really want to run track of do any of the field events. Others believe they are too slow and then the last handful of people are scared to risk getting injured. Track & Field may seem like one of the best sports to keep the human body healthy and active. But the question is how stress is but on the human body muscles when running competitively? Is it enough to pull a muscle or how about the risk of falling
Area of the Long Point Fault The Long Point Fault is located in Harris County, which covers 83,450 square miles located with in Houston, Teaxas City Limits. Research specifies that there are three sections of the Long Point fault that appear to be active; some sections of the Long Point fault have averaged more than 2 cm per year of vertical offset over the last 20 years. Evidence of the faults concludes it is a natural fault. The reason for activity is not caused by man, even though man’s activities
during running. Playing football you may encounter the same injuries as playing basketball and running or even worse if playing full contact football. The most common sports injury is strains and sprains that occurred during sports activity. Stretching and warming up the body is a good activity to prevent strains and sprains this is commonly done before doing any physical

The Skill of Writing Writing and reading are two essential skills that we need to have in order to succeed in any field of study that we have chosen. Without these two we would not be here, wouldn’t be writing right now and would be considered the lowest class of our society. There are different aspects of writing that each of us may, or may not, excel at. Some of us are creative enough to write short stories or even novels on fiction while others, like me, are better at writing essays. To accomplish
Representation of Society in Euripides' Medea During the time of Euripides, approximately the second half of the fifth century B.C., it was a period of immense cultural crisis and political convulsion (Arrowsmith 350). Euripides, like many other of his contemporaries, used the whole machinery of the theater as a way of thinking about their world (Arrowsmith 349). His interest in particular was the analysis of culture and relationship between culture and the individual. Euripides used his characters
Eye Strain as a Result of Computer Use In the twentieth century, technology is at an all time high in the world. This technology includes research, stock market shares, computers, medical advances, and a vast variety of other things. Among the advanced technology is a break through of computer use. Almost everyone at sometime in their day is using a computer for one task or another. Computers have taken the world and reshaped the possibilities of ideas and dreams in the past decade. Millions
Medial Epicondylitis occur in the forearm, on the inside of your elbow. Medial epicondylitis is when the inner forearm muscles (called the forearm flexors) are overused by activities dealing with wrist movement. When these tendons that attach to the medial epicondyle (bony tip on elbow) are swollen it causes medial epicondylitis. This injury can also be referred to as “Golfers Elbow” because it is more common in golfers. The injury can happen in any activity, but affects the most dominant arm. Signs
lift an object if it is too heavy or too bulky for good balance. Get help or use mechanical aids such as a dolly or hand truck. 2. Keep the load as close to the centre of your body. The farther the load is from the small of your back, the greater the strain. That is the reason a heavy compact load is easier to lift than a bulky, lighter load - you just cannot get the bulky object close to you. The best way to handle a compact load is to squat down close to the load with one foot alongside it and the
about the illness or disability, that this will never help the child or the parent. I also found it interesting when she spoke about support within the family as well as outside the family. Lastly, I thought it was important for her to mention the strain that a family with a disabled child will incur. Reflection: ...
What are the differences between an acute injury and a chronic injury or disease? An acute injury is one that happens during a single event not over a period of time while a chronic injury could develop or worsen over time. Chronic injuries usually happen as a result repetitive trauma to the same area injuring it worse every time. If not treated, an acute injury can turn into a chronic injury. There are many times of acute injuries, many of which result from sporting accidents. An acute injury is
Munson, Young, Okiishi, and Huebsch (2010), is defined as “a substance that deforms continuously when acted on by a shearing stress of any magnitude” (p. 4). Fluids can also be described as a component that constantly undergoes physical changes due to shear force which is a force that acts tangentially to its area (Massey & Ward-Smith, 2012). Fluids have certain properties that liquids and gases have in common which differentiate it from solids such as its ability to flow and change shape. However, the
Introduction and Literature Review Context Freeform surfaces prevail in contemporary architecture. Over the past two decades there has been a surge in the use of smooth, curved surfaces, which can be attributed to improvements in 3D modelling techniques and advances in finite element analysis. The complex geometries, examples of which can be seen in the Figure ? below, pose challenges in developing a feasible building envelope using conventional building materials such as steel and concrete. This
Composites are similar to essays; they are both an arrangement of parts coming together. Composites, however, have two essential phases: matrix and dispersed phase. The matrix’s responsibility is to be covering the materials being used to form a new type of supply. Composites are also known as two or more type of materials being combine to create a new material that could be used in different real world applications. Commonly, composites are formed because it could be reusable, cheaper and sometimes
