ME 2330 By K. L. Ting 5. Tangential and Normal components Let R(s) = x(s) i + y(s) j represent a curve and s is the independent parameter representing the arc length of the curve measured from a reference point. At s and s’, a particle moves from P to P’ and the displacement is dR (Fig. 1). If P and P’ is infinitesimally separated, i.e. ds= s’-s → 0, l dR l = ds, dR/ds = ut.

ut is a unit vector (called unit tangent) tangent to the curve at P (Fig. 2). At P and P’, let ut and ut‘ be the unit vectors in the tangent direction. The lines normal to ut and ut‘ intersect at O (Fig. 2). With ds → 0, point O is the center of curvature and ds/dθ = ρ where ρ, called radius of curvature, is the length OP. In Fig. 3, one may observe that dut is normal to ut and since ut and ut’ are unit vectors, dut/dθ is a unit vector, designated as un. un is the unit vector (called unit normal) in the direction from P to O. That is, dut/ds =(dut/dθ)(dθ/ds) = (1/ρ) un or dut/ds = k un

where k (= 1/ρ = dθ/ds) is the curvature at P.

With a Cartesian coordinate system, the radius of curvature at (x, y) can be calculated as

ρ = [1 + (dy/dx)2]3/2/ ld2y/dx2l or ρ=

where the dots on x and y represent the first and second derivatives with respect to any independent parameter, such as t or s. In a circle, the center of curvature is the center of the circle and the radius of curvature is the radius of the circle.

Let a particle move along a path R(s). Differentiating R with respect to time yields V = dR/dt = (dR/ds)(ds/dt) = ut where it again yields a = dV/dt = where = ut )dt = ut + (dut /ds)(ds/dt) = ut + ( 2/ρ)un. at represents the tangential acceleration, which is caused by the is the tangential velocity or the speed of the particle.

The Hinton Helper Passage

...of the South” Hinton Rowan Helper argued that by over focusing on slavery the slave failed to nourish its other economic facets and had become over reliant on the northern economy. Helper decried that the south had “no foreign trade,” and that southerners contributed nothing to “literature, polite arts, and inventions of the age.” He believed that the slavery was not only ruining the economics of the south, but also its culture, and the minds of its very people. Helper also declared that the talented intelligent southerner would have no reason to stay in the south and this bothered him very dearly; later in the essay Helper mentioned that non slave holding whites in the south are among the most illiterate people in the world. Helper felt that slavery was bringing economic and cultural destruction to his home land. In addition to slavery making the south subservient to the north, Helper also argued that southerners outside the slavery system were severely disadvantaged. He claimed that poor southern whites were “regarded with less esteem than Negroes” and were “infinitely worse off” than even their slave counterparts. Helper was arguing that over focusing on slavery caused the government to neglect those not exploiting slave labor to get by. Not only did this lead to poverty for many poor white folk but it also gave tremendous power to a select few slave holders who became disproportionally wealthy and controlled and unfair amount of society. Helper also bemoaned southern......

Case of Industrial Disputes

...services--Held termination was not retrenchment and consequent compliance with section 25-F not necessary--But termination held unjustified and inequitable--Scheme formulated by the Supreme Court. For relief to drivers--Directions for giving retirement benefits, providing alternative jobs and payment of compensatory amount proportionate to length of service rendered by the drivers. Matter/facts - The termination of services of helper (in C.A.No. 1862) was unjustified and also illegal being in contravention of the provisions of Section 25-F of the Act. The High Court erred in treating his case on par with cases of other drivers. The appellant-workman will, therefore, be entitled to his retirement benefits as a driver from the date of his employment as a helper. He would further be entitled to be reinstated in service as a helper with all arrears of back wages as a helper. In case he opts for receiving the compensatory amount under the scheme framed by this Court, he may do so for the period beginning from the date from which his services as a helper were terminated. [637D-F] 627 The appellants (in C.A. No. 1859-61) were appointed as drivers and had put in a long service to the satisfaction of the respondent Corporation. Subsequently on their medical examination it was found that they had developed defective eye-sight i.e. they did not have the required vision for driving the buses.

Helper Questions About Fungi

...Question about topic: Why does fungus grow in caves more than out in the open sun? Background Information: Fungi enjoy living in damp and dank areas. For example near large water sources, such as, rivers, streams, and springs in the woods. They are unable to be self-sufficient due to being unable to produce their own food independently with photosynthesis. They must absorb nutrients vital to sustain themselves that is most readily found in woods or forests with water sources in or near by them. The fallen leaves and flowing water bring many nutrients to them through the flow of the water as well as the decay of the leaves that contain some of the nutrients of the tree it once was a part of. They are also capable of living inside plants and animals. Also aiding in the decomposition and fertilization, fungi help decompose plant and animal materials (i.e. waste, flesh, etc.). My hypothesis: I hypothesize that fungi grow in dark areas with water sources and other miscellaneous animal traffic due to the independence from the sun and animal traffic leaving waste and other materials as they come and go. Experiment: The experiment is to first purchase fungi and split them into two equal amounts. Once separated take the first half and plant them next to the flowing water source leaving openly exposed to the sun. Next take the left over half of fungi, plant them in a dark closed in area with the flowing water, such as a wood box flipped upside down. Once that is done set...

Housing Helpers Case Study 1

...Housing Helpers Case Study 1 By Kevin Wilkerson BUS-4046 Employee and Labor Relations U07A1 Instructor Andrew Ansoorian May 26th, 2014 As the contract negotiation continues between Beth and Jim: Beth: That sounds very tempting Jim, but even though the CPI has risen by just 2%, the cost of living has risen by 3.5% and the working force needs that money now to support their families. Jim: Well, is there any other thing that we can propose that might get us closer to an agreement? Beth: Well, Jim, I think that we will hold a membership meeting to see where the members stand on this issue and your offer of 2% each year for 4 years. Jim: Ok, we will reschedule another session after the meeting. Another meeting resumes: Beth: The members have met and we have a couple of other proposals that might be of interest to you. Jim: Ok, what do you have in mind? Beth: We would like to propose a 3%. Cost of living allowance increase as well as an additional 5 days paid vacation for all employees, and work hours that are flexible such as 4 10 hour days or a 5/4/9 schedule which would keep production up, but allow the employees to spend more time with their families also. Jim: Beth, we simply cannot afford for employees to receive such a pay increase right now, but the alternative work hours might be something that we can talk about. Beth: HR has run the numbers, and the number of employees that have seniority and are getting up there in age are costing us more......

Being an Effective Helper

...Being an Effective Helper Some people are limited in their social interaction; this may be a result of how they were brought up by their parents. Maybe they were home schooled or sheltered as a child. Maybe they were simply not allowed to interact with anyone outside of their family unit. Not every person is capable of learning the same way. As an instructor, you have to be aware of this fact and be able to recognize a person’s inability to learn a certain way and to help provide guidance in the correct direction, a path that will allow them to find their own way of learning the specific task sought after. Personally, there are multiple situations or client personalities that I feel that I would have difficulties in helping. The majority of them come from previous encounters with those types of situations or types of personalities. I know that for myself to improve as an instructor and a helper that I must find a way to see beyond these prejudices that I hold. It can be difficult to get past a certain distaste, as a small child my parent’s forced me to eat Brussels sprouts, and to this day they absolutely disgust me. I have tried to eat them on numerous occasions and I am not sure if it will ever happen. The first example that comes to mind is dealing with stubborn and difficult people. In my experience as a flight instructor, I have encountered this type of person in two different aspects. The first is that they believe that they are better than they actually......

How to Be a People Helper

...How to Be a People Helper is a book by Dr. Gary R. Collins, it is based on the belief that people helping must be built on the Bible, God’s Words, and must be consistent with the Great Commission in which Jesus commanded his followers to make disciples of all nations. This edition has been revised, and changes were added in counseling techniques, approaches to training, research findings, and types of problems. There are many books on counseling; however, How to Be a People Helper has continued to be the basis for people helping training programs in a number of churches, colleges, and Christian organizations. This book is translated into several foreign languages and it is written to help people become skilled Christian people helper who serves Christ by helping others. Dr. Gary R. Collins is a Clinical Psychologist and is the President of the American Association of Christian Counselors and the editor of Christian Counseling Today. He refers to Christians who wants to learn counseling skills as people helper or lay-counselor. He admits that lay-counseling may be even more useful than professional counseling. He states that while professional psychological help is vital in dangerous life-threatening situations, lay-counseling is the matter of everyday life and therefore, is compulsory as the means of keeping people in a healthy psychological state in their daily routine. He believes that psychological help should not be a mere treatment with the help of test and......

Social Evaluation of Preverbal Infants

... The authors of the article, Hamlin, et al. hypothesized that preverbal infants do social evaluation. The hypothesis is then confirmed with the results suggesting, “preverbal infants assess individuals on the basis of their behavior towards others” (Hamlin et al. 2007). They prefer a helpful individual to a hinderer, prefer a helper to a neutral individual, and prefer a neutral individual to a hinderer. They assessed 6 and 10-month-old infants by measuring their looking times and their preference of choice. They conducted 3 experiments and in these experiments they used a helping stimulus, a hindering stimulus and a neutral stimulus. In experiment 1, when infants were encouraged to choose between the helper and the hinderer, they prefer to choose the helper. When 10-month-olds, but not 6-month-olds, watched the climber approaching the hinderer which is novel to infants, they looked longer at the screen, compared to when the climber approaching the helper which is unsurprising. In experiment 2, “infants overwhelmingly chose the helper when this action was embedded in a social context”. In experiment 3, it is clear that the infants prefer the helper and avoid the hinderer when they were both paired with a neutral stimulus. In general, young infants have a preference for those who cooperate with others to help them achieve their goals, and a dislike for those who impede others goals. These findings are very interesting because it made me think about various subjects related...

Client Paper

...Client Paper Holly Regan BSHS/305 December 15, 2014 Cassidy Hawf Client Paper In order to be a proficient and efficient helper in all facets of the helping field of human services, the helper must first be diverse. Diverse individuals have an upper hand when it pertains to assisting client needs efficiently and their expertise in the proper helping skills to use for each range of problem. The range of problems client's encounter is addiction, homelessness, or mental illness. It is within these ranges of problems the helper must implement a variety of skills to assist the client on how to manage effectively or cope with such issues. When envisioning a client and the problems that can be attributed from the past, the present, and in the future, the helper needs to look at the whole person and not just the problems directly. “Problems for clients are rarely single issues, and the human service professional should approach each client with the expectation of more than one problem. In fact, one problem can cause, influence, or at the very least be related to other difficulties,” (Woodside & McClam, 2011). Range of Problems The range of problems that a client may face can be short-term or long-term. Short-term problems are issues such as being an unemployed or displaced worker, poor living environment, or spousal abuse can be resolved by implementing a plan that will affect each problem by creating a positive outcome. Long-term problems like addiction,......

...relationship. The helper (human service professional) brings their training, knowledge and skills to help with working through the client’s problems. According, An introduction to human services (7th ed). Client and helper relationships have a few distinct characteristics: First, helping relationships are brought together for an agreed-upon purpose and are goal oriented. Second, a helping relationship happens within a time period which usually means that is occurs over several sessions, depending on the problems and issues that the client faces. The relationship ends when the expressed goals are accomplished. Third, the helping relationship carries authority. Meaning that the helpers knowledge and skills that allows them to work with the client toward resolving the problem. Finally, this relationship is for the client. The client is the focus always, their strengths, problems and concern are reason the relationship exists. There are five stages of the helping process is Preparation, Client Arrival, Exploring the problem, Intervention Strategies and Termination. Before the initial meeting between the client and the helper, the helper should make that all preparation is complete. This include the physical setting that should make the client comfortable and necessary paperwork completed. Upon the clients arrival and they have adapted to the surrounding the helper should inquire what problems did that client want to share. During this part of this process the helper has to......

...IT1115 Exercise 4 Virtual and Cloud Computing 1. There’s a huge difference between client/server and peer-to-peer networks. For instance, a peer-to-peer network has no central server. Each workstation on the network shares its files equally with the others. There’s no central storage or authentication of users. Conversely, there are separate dedicated servers and clients in a client/server network. Through client workstations, users can access most files, which are generally stored on the server. The server will determine which users can access the files on the network. Peer-to-peer networks should be installed in homes or in very small businesses where employees interact regularly. They are inexpensive to set up (comparatively speaking); however, they offer almost no security. On the other hand, client/server networks can become as big as you need them to be. Some support millions of users and offer elaborate security measures. As you can imagine, client/server networks can become very expensive. 2. The main advantages of using virtual machines are Multiple OS environments can exist simultaneously on the same machine, isolated from each other; Virtual machine can offer an instruction set architecture that differs from real computer’s; Easy maintenance, application provisioning, availability and convenient recovery. The disadvantages of using virtual machines are When multiple virtual machines are simultaneously running on a host computer, each virtual machine may......

Human Services and Helping Skills

...the most important skills for a helper to practice. When you actively listen to the client it is easier to relate to the individual and to get a better understanding of what exactly the problem is, as well as what caused the problem. Active listening will and remaining nonjudgmental will help the client to: feel more comfortable, more relaxed, important, understood, be more trusting and possibly even forth coming with information. Active listening, being nonjudgmental and observing will help with assessing the problem and help the client realize that you care and want to provide guidance so they can achieve the goal of self-sufficiency. Communication is another vital helping skill for human service professionals to practice. Communication can be verbal as well as nonverbal. One important thing to remember when communicating verbally is the tone of voice used. When speaking, the helper needs to speak with a soft, calm, slow and steady voice keeping and even tone throughout the conversation. The helper should also not speak until the client is finished because cutting a speaker off in the middle of talking shows lack of respect and could potentially offend the client. Nonverbal communication is another form of communicating, and it is just as important as verbal communication. Examples of nonverbal communication consist of eye contact, body language (posture, arm crossing, foot tapping and more), hand shake, posture, smile, and more. The helper must be mindful of body......

...will be able to offer them. Keeping a low even tone and making eye contact are very important as it lets your client know that you care and want to help them. Invite them in and to the seating area where you will be able to start building a relationship of trust. 3. Exploring the problem(s) – At this point the helper should be asking the client what they think the problem(s) are and be asking questions of the client to try and ascertain if the client has a realistic idea of their issues or if the helper sees more or different issues than the client. Trying to get to the root issues so that they can then address these problems and work towards resolution. 4. Intervention – At this stage in the helping process the helper and the client have agreed on the issues at hand and it is time to discuss how to move forward and get a plan in place by setting goals. 5. Termination – Once the helper and the client have followed the intervention plan and all goals have been met then the end of the helper/client relationship is called termination. (Woodside & McClam, 2011, chapter 7) It is very important to know that there are certain things that you as a helper can do to make your job go more smoothly. Knowing how to work with people, make the feel comfortable and at ease talking to you even if they are there involuntarily as a condition of their probation or parole or because DCF is involved in their case. Communication is key and you will both give and receive verbal......

Filipino Helpers in Hong Kong

...Filipinos helpers in Hong Kong are at the risk of being maltreated Introduction Castillo Clariza Avenales who was in her age of 33, had her right thumb being chopped by her male employer after she reported his sexual misconduct to his wife last year. She was not the first one experienced such an unfortunate incident. Hong Kong, which comes to the top rank in world domestic labor employment, has long been seen as somewhere nearby to earn good salaries for better livings by the Filipinos. However, these people might place themselves under the danger of being abused in this workplace. In a 2001 survey conducted by the Hong Kong Human Rights Monitor which is a shadow committee of the United Nations, 1000 maids out of 2500 claimed they were physically abused while 175 of them said they were either harassed or raped. (Stafford, 2001, p. 5) This number was underestimated, according to the Hong Kong Overseas Maid-Employer Association dean, since it was not precise and scientific enough as the police figures which the authorities never revealed. It is actually not uncommon to see Filipinos getting involved in discrimination, unfair treatments, and even violence. Discrimination, unfair treatments, abuses and violence Gatmaytan (1997) stated that “Filipinas are imported by other countries for jobs their own citizens will not perform and for wages domestic citizens would not accept,” (p. 247) which is very true. In Hong Kong, Filipinos are receiving salaries that two times or...
