INTRODUCTION

A hydraulic fluid power system is defined as a means of power transmission in which relatively incompressible fluid is used as the power transmitting media. The primary purpose of hydraulic system is the transfer of energy from one location to another location and this energy into useful work. In this project fabricated model of Multipurpose Hydraulic angle forming machine will describe. Metal forming can be defined as a process in which the desired shape is obtained through the deformation of metals plastically under the action of externally applied force. The type of drive depends upon the length of the stroke needed and loads on the ram. In this project we have applied to the hydraulic force for the angle forming machine. The Hydraulic drive is used when a very heavy pressures is required on the ram this is used for drawing and forming operation .System pressure can be generated in the form of any physical action which results in a compression over the Hydraulic system.

BASIC PRINCIPLE 2.1 PASCAL’S LAW Fig no:1 * Pascal’s law states that the pressure applied anywhere to a confined liquid it transmitted equally to every portion of the surface of the containing vessel. * Refer the above fig. When a force is applied to the liquid by a piston, the liquid transmits this force equally to all surfaces of the container.

2.2 HYDRULIC PRINCIPLES

There are certain governing principles in a hydraulic system
1. All liquids are non-compressible and can be used to transmit power.
2. Any load to be lifted offers resistance to flow of liquid. This resistance to flow is pressure.
3. If the capacity of the pump is more, then it pumps out more liquid. If it pumps out more liquid, then it makes the hydraulic actuators (hydraulic cylinder) (or)…...

Mortgage Calculations

...Mortgage Calculations Alisha Logue MAN 222 Instructor Alan Jones Sept. 26, 2013 Calculating a mortgage loan can be difficult. With the help of www.mortgage.com, they offer an online calculator to assist you. By using this tool you are able to plug in all the needed figures and find out the totals of taxes, interest, etc. One feature it also allows you to do is see totals with or without extra payments. (citigroup.com)Extra payments towards your loan's principal can substantially decrease the amount of interest you pay over the life of your loan. By paying extra amounts each month, you will be able to repay your loan much more quickly(2013). For a $225,000 home, the mortgage loan is $21,375. A term of 15 years with a 5% interest rate with no extra payments is going to be higher than having extra payments. With no extra payments added, it will take the whole term of 15 years to pay off the loan. Adding a $100 extra payment will take only eight years and two months. You save about $4364 in interest paid by adding an extra payment each month. Adding an extra payment a month, the taxes and insurance and the mortgage insurance would be the same if you did not have an extra payment. Taxes and insurance would run about $123 and the mortgage insurance $0. Between having an extra payment and not having one, the principal and interest is $100 difference. The principal and interest total is then $169 with no extra payment, $269 with an extra payment. Total......

Stress

...Jared Sanchez Contemporary Health II October 20, 2012 Stress: The Constant Challenge Coping with stress can be a constant challenge and it can be hard for someone to handle by themselves. Stress can come from many things such as failing a test, getting into a car accident, and even a break up with a significant other. Stress can be developed by anything that makes you worry about more than you should be worrying about it. Stress-producing factors can be pleasant or unpleasant and can include physical challenges, goal achievement, and events that are perceived as negative. Dealing with stress is hard because without support someone can be really hurting themselves and not even know it. It’s physically, emotionally, and mentally impossible for someone to carry the weight of the world on their back no matter whom you are. Stress, such as many other terms, is misunderstood by people because they don’t really know the precise meaning. Stress is the general physical and emotional state that accompanies the stress response. Stressors are the specific reasons that stress happen. A stressor is any physical or psychological event or condition that produces physical and emotional reactions. First dates with a girlfriend or an upcoming final exam are examples of stressors. Sweaty palms and a pounding heart are symptoms of the stress response. Every time someone goes through stress there is always a response to it. Responses to stressors however can include a wide variety of......

...Stress When the body is in stress it creates glucocorticoids, which are made in the adrenal glands. These glucocorticoids are epinephrine and cortisol, which both accelerate immune cells to move from the bloodstream into the tissue if needed to fight against an infection, and when the infection is gone, they return the body to homeostasis. When a person is in stress, these glucocorticoids do the same thing as if they were fighting an infection; however, if the body is in constant stress, it will continue to "fight the infection" and will not return the body to homeostasis. This can cause glucocorticoid receptor resistance and can cause the body to develop an even higher risk of depression, upper respiratory infections, diabetes, autoimmune disease, slower healing, and even cardiovascular disease (1). The body's stress response kicks in when you feel there is a possible threat, which is necessary to ensure the best chance of survival. In the brain, the hypothalamus and the pituitary control the stress response. The adrenal glands also aid in controlling stress response by the kidneys. When the brain senses danger, it sends nerve signals down the spinal cord to the adrenal glands telling them to release adrenaline, which then increases the sugar in the blood, the heart rate, and the blood pressure. The hypothalamus sends signals to the pituitary gland telling it to release factors that travel quickly through the blood stream and stimulate the adrenal cortex to produce......

...Work related stress develops because a person is unable to cope with the demands being placed on them. Stress, including work related stress, can be a significant cause of illness and is known to be linked with high levels of sickness absence, staff turnover and other issues such as more errors. Stress can hit anyone at any level of the business and recent research shows that work related stress is widespread and is not confined to particular sectors, jobs or industries. That is why a population-wide approach is necessary to tackle it. Definition of stress Stress can be described as: "The adverse reaction people have to excessive pressures or other types of demand placed on them at work." Stress is not an illness – it is a state. However, if stress becomes too excessive and prolonged, mental and physical illness may develop. Well-designed, organised and managed work is generally good for us and when insufficient attention to job design, work organisation and management has taken place, it can result in Work related stress. Work related stress develops because a person is unable to cope with the demands being placed on them. Stress, including work related stress, can be a significant cause of illness and is known to be linked with high levels of sickness absence, staff turnover and other issues including fatigue which in turn can lead to errors in the workplace. We can say that “Stress causes some people to break, and other to break records.” Stress or pressure......

(ii) L Ltd needs to have incentive for the change. - Can transfer pricing method be changed to provide the incentives? - Are there savings in selling and distribution to decrease the TP? - Would negotiation be effective? - How important is divisional autonomy? c) to recommend, with supporting calculations, what transfer prices you would propose.  M Ltd has the capacity needed, so transfer price need to be > variable costs  Assuming that we only change the price of the extra 8000 units: L Ltd’s profits increase if its variable costs are reduced more than £1. This is because selling 8000 units more reduced L ltd’s profits by £8000. M Ltd should be able to cover its variable costs to increase its profits. VC= £200/1000l = £0.2/l. One drum needs 25 l -> variable costs £5 per drum. £5 < TP < £8 where TP is the transfer price for the extra units. ...

Stress

...Extra Credit: Stress Documentary Stress: Portrait of a Killer, an enticing documentary about the effects of stress on the human body and how it shapes society. The documentary tackles various aspects of how stress affects mammals, from studies of baboons in Kenya by a Stanford Neurologist to how humans with different ranks in society react to stress. A key in the documentary of which I found most interesting is how humans find it difficult to turn off the stress response feeling after a stressful event. 30 years ago scientists found out that stress wasn’t the result of just stomach ulcers, but stress itself causes the immune and digestive system to not function properly which causes the bacteria in the stomach to give people the sensation that the ulcers are the reason behind stress. There is various health risks discovered through the study of stress on baboons. The two hormones adrenaline and glucacorcacoids exerted from the baboon’s blood revealed that stress could cause major cardiovascular diseases that can lead to heart attack. Stress revealed increased heart rates and blood pressure, primary a result of damaged artery walls, restrict blood flow and clog blood canals, which can lead to heart attack and death. Other studies observed on obese people showed that stress can lead to dangerous fat cells being stored around the abdomen which causes different reactions to hormone growth and attitude. Dopamine is another hormone discovered to be crucial in turning stress into......

Return Calculations

...Chapter 1 Return Calculations In this Chapter we cover asset return calculations with an emphasis on equity returns. Section 1.1 covers basic time value of money calculations. Section 1.2 covers asset return calculations, including both simple and continuously compounded returns. Section 1.3 illustrates asset return calculations using R. Updated: June 23, 2011 1.1 The Time Value of Money This section reviews basic time value of money calculations. The concepts of future value, present value and the compounding of interest are dened and discussed. 1.1.1 Future value, present value and simple interest. Consider an amount $ invested for years at a simple interest rate of per annum (where is expressed as a decimal). If compounding takes place only at the end of the year the future value after years is: = $ (1 + ) × · · · × (1 + ) = $ · (1 + ) (1.1) Over the rst year, $ grows to $ (1+ ) = $ +$ × which represents the initial principle $ plus the payment of simple interest $ × for the year. Over the second year, the new principle $ (1+ ) grows to $ (1+ )(1+ ) = $ (1 + )2 and so on. 1 2 CHAPTER 1 RETURN CALCULATIONS Example 1 Future value with simple interest. Consider putting $1000 in an interest checking account that pays a simple annual percentage rate of 3% The future value after = 1 5 and 10 years is, respectively, 1 5 10 = $1000 · (1 03)1 = $1030 = $1000 · (1 03)5 = $1159 27 = $1000 · (1 03)10 = $1343 92 Over the rst year, $30 in......

Stress

...A Conceptual Analysis of Stress Alanda James University of South Alabama Abstract Stress is a prominent factor that affects the lives of people who deliver healthcare to patients every day. It is important to examine the concept because unhealthy stress can cause multiple effects on the caregiver and patient. Positive forms of stress can be beneficial to practice, and negative forms of stress can put practice in danger. A conceptual analysis of stress will strategically define the concept, explore antecedents, and pinpoint consequences associated with stress. The mental and physical effects of stress will be examined, and the link between effects and antecedents will be established. The antecedents of stress are essential to identifying the underlying problem, and prevention methods can be implored once those problems have been identified. In addition, cases will be presented reflecting the use of stress to educate the reader with knowledge and recognition of the concept. A model case, related case, contrary case, and borderline case are given in the text as examples to illustrate the concept of stress. A Conceptual Analysis of Stress Stress is a concept that derives from strain placed on a human being. Dictionary.com (2012) defines stress as “mental, emotional, or physical strain or tension”. Positive and negative aspects of stress exist depending on the particular incident or situation. Stress can be activated when a student is nervous about presenting a speech,...

Stress

...DEFINITION OF STRESS Based on Organizational Behavior text book, stress is defined as an adaptive response to a situation that is perceived as challenging or threatening to a person’s well being. Stress is a physiological and psychological condition that prepares us to adapt to hostile or noxious environmental conditions. Stress is typically described as a negative experience. This is known as : Distress : the degree of physiological, psychological and behavioral deviation from healthy functioning. Eustress : a necessary part of life because it activates and motivates people to achieve goals, change their environments, and succeed in life’s challenges. DEFINITION OF STRESSOR/CAUSES OF STRESS Stressors can be defined as any environmental conditions that place a physical or emotional demand on a person. There are three of the most common stressors. STRESSOR EXPLANATION Harassment and Incivility Psychological harassment – includes repeated and hostile or unwanted conduct, verbal comments, actions, and gestures that affect an employee’s dignity or psychological or physical integrity and that result in harmful work environment for the employee. Sexual harassment – a type of harassment in which a person’s employment job performance is conditional and depends on unwanted sexual relations (called quid pro quo harassment) that unreasonably interferes with work performance or creates an intimidating, hostile, or offensive working environment.
