The Physics Of A Physics Class For Four Years Now - 895 Words

1) I was taught early on by Dr. Jacobson in PHYS 109 to employ a common five step process that I always use in physics (every physics class for four years now). The steps are: 1) Identify the givens (draw/label), 2) Identify what it takes to be solved (or what specific quantity the question asks for), 3) Write down all useful relations involving both the givens and what is needed to solve, 4) Attempt to solve, 5) Reflect on the feasibility of solution or correctness. This process is good and does not fail me; however, I always use it no matter if a problem is trivial or not. My consistent leaning on this process has a downside. It not only restricts me to a sequential form of thinking about solutions (possibly masking alternative approaches), but I often take much longer on physics problems than most. I am the type of student with good to high grades on homework assignments, but poor- passing, but poor performance on tests. I don’t believe this category of student is uncommon. As a student, I feel that I have comparably infinite time to work on a tough homework problem than the blip of time allotted to a problem on a test. I think other students share that outlook. To elaborate more on the downside of my loyal use of the above process I note that there are many problems in physics with different approaches to solutions (it’s one of the things I love about physics). By sticking hard to the above process, I often grab the first approach that pops out of relations in stepShow MoreRelatedMy Favorite Weekend Activities At Cal Poly Pomona986 Words   |  4 Pagesprogramming class, my application was the most impressive.

Balancing of Rotating Machines Free Essays

BALANCING OF ROTATING MACHINES The first thing to be explored to control vibrations is to try to alter the source so that it produces less vibration. This method may not always be feasible. Some examples of the sources of vibration that cannot be altered are earthquake excitation, atmospheric turbulence, road roughness, and engine combustion instability. We will write a custom essay sample on Balancing of Rotating Machines or any similar topic only for you Order Now On the other hand, certain sources such as unbalance in rotating or reciprocating machines can be altered to reduce the vibrations. This can be achieved, usually, by using either internal balancing or an increase in the precision of machine elements. The use of close tolerances and better surface finish for machine parts (which have relative motion with respect to one another) make the machine less susceptible to vibration. Of course, there may be economic and manufacturing constraints on the degree of balancing that can be achieved or the precision with which the machine parts can be made. The presence of an eccentric or unbalanced mass in a rotating disc causes vibration, which may be acceptable up to a certain level. If the vibration caused by an unbalanced mass is not acceptable, it can be eliminated either by removing the eccentric mass or by adding an equal mass in such a position that it cancels the effect of the unbalance. In order to use this procedure, we need to determine the amount and location of the eccentric mass experimentally. The unbalance in practical machines can be attributed to such irregularities as machining errors and variations in sizes of bolts, nuts, rivets, and welds. In this section, we shall consider two types of balancing: The static unbalance can be corrected by removing (drilling) metal at the chalk mark or by adding a weight at 180 ° from the chalk mark. Since the magnitude of unbalance is not known, the amount of material to be removed or added must be determined by trial and error. This procedure is called single-plane balancing, since all the mass lies practically in a single plane. †¢The single-plane balancing procedure can be used for balancing in one p lane that is, for rotors of the rigid disc type. If the rotor is an elongated rigid body, the unbalance can be anywhere along the length of the rotor. In this case, the rotor can be balanced by adding balancing weights in any two planes. For convenience, the two planes are usually chosen as the end planes of the rotor. However, in many practical applications, such as turbines, compressors, electric motors, and pumps, a heavy rotor is mounted on a lightweight, flexible shaft that is supported in bearings. There will be unbalance in all rotors due to manufacturing errors. These unbalances as well as other effects, such as the stiffness and damping of the shaft, gyroscopic effects, and fluid friction in bearings, will cause a shaft to bend in a complicated manner at certain rotational speeds, known as the whirling, whipping, or critical speeds. Whirling is defined as the rotation of the plane made by the line of centers of the bearings and the bent shaft.

Boy Scouts of America free essay sample

The Scout Oath reads, On my honor I will do my best to do my duty to God and my country and to obey the Scout Law; to help other people at all times; to keep myself physically strong, mentally awake, and morally straight. The Scout Law states, A Scout is trustworthy, loyal, helpful, friendly, courteous, kind, bedient, cheerful, thrifty, brave, clean, and reverent. In addition to the mission, Boy Scouts of America have a vision statement: The Boy Scouts of America will prepare every eligible youth in America to become a responsible, participating citizen and leader who is guided by the Scout Oath and Scout Law. Boy Scouts of America was established in 1910 as a part of the international scout movement and was chartered by Congress in 1915. In 1910 BSAs mission was to teach [boys] patriotism, courage, self-reliance and kindred values. Although the mission is worded different today, it till holds true to the core mission of teaching boys ethical values. We will write a custom essay sample on Boy Scouts of America or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The National Executive Board governs the Boy Scouts of America, however the National Council runs Boy Scouts of America. The National Executive Board are elected members, regional presidents and up to five youth members. The 2012 report listed 76 members. The board is directed by an elected volunteer, the National President. The CFO is given the title Chief Scout Executive and serves as the secretary of the National Executive Board and is a nonvoting member. To date there have been 1 1 Chief Scout Executives and 33 National Presidents. Wayne Perry, a retired businessman, is the current National President. In May 2014 Robert Gates, a retired civil servant and university president, will take over from Perry and serve as the National President. Wayne Brock was appointed to Chief Executive Scout in August 2012. The National Council is a much larger entity than the executive board. The council consists mostly of volunteer Scouters who are elected National Officers, Executive Board Members, regional presidents, local council representatives, members at large and honorary members. The councils role is to promote the Scouting program within a designated geographic area. They have four major functions, membership, fund development, maintain standards and policies and serve organizations using the scouting program. Daily operations of the National Council are directed by the Chief Scout Executive and other national professional staff however the whole National Council only meets on an annual basis. BSA can be summed up as one movement with six programs, Tiger Cubs, Cub Scouts, Webelos Scouts, Boy Scouts, Varsity Scouts and Venturing. All of the programs have the same ims of building character, learning the responsibilities of citizenship, and developing personal fitness. The programs mostly differ according to age group. Tiger Cubs is for boys in first grade. Cub scouting is for boys between the ages of 7 to 10. Webelos Scouts is for 10 year old boys. Boy Scouts program is for boys between the Venturing is for young men and women between the ages of 14 and 21. Tiger Cubs, Cub Scouts and Webelos Scouts are family and home centered programs whereas Boy Scouting is designed as an outdoor program. Varsity Scouting emphasizes high dventure and Venturing is more of a focus on leadership and growth through teaching others. Exhibit 1 shows the membership of each program at the end of 2012. Cub Scouts (including Tiger Cubs and Webelos Scouts) had the largest membership with Just over 1. million members. It seems the introductory programs are more popular than other programs. As a whole BSA is well known throughout America, in fact, they are a big part of American Culture. People associated with BSA are usually described as earnest and honest individuals and media continues to highlight Scouting community projects and acts of service. The BSA isnt all good though, like all organizations there is a sha dow side. In BSAs case, this shadow side includes numerous sexual abuse cases and discrimination against homosexuals. Prior to 1994 there were 2,000 reported cases of abuse. The BSA introduced the Youth Protection Program in 1988 leading to more accountability among leaders and less opportunities for abuse. More recently, BSA has been put in the spotlight because of their stance on homosexual leaders. In July 2012 a BSA committee reviewed the BSAs stance on homosexuality and came to a unanimous decision ecommending that the BSA should maintain their policy about not allowing homosexual adult leaders. This was followed by cuts in financial ties and a great deal of public oppression. In May 2013 the BSA National Council voted to remove the policy, emphasizing that membership should not be based on sexual orientation because all sexual conduct is not allowed. All in all BSA is a well-organized organization with a long-standing history that has had a significant impact on American culture. Its deep roots probably lead to ingrained business practices that re hard to change although the change in policy concerning homosexuality proves that the National Council can change policies if they can gain a majority for a certain decision.

Question: Write a memo in response to the case study . The memo must be logically structured, free of grammatical errors, professionally styled; in addition, follow the writing conventions for memos as discussed in the lecture. Answer: To: Mrs. Rania Singh, Customer Service Agent. From: The Director of Sigma Globe Date: 30th July 2017 Subject: To obey recommendations discussed in the memo The propaganda of this memorandum is to give an insight on the changes in the information provided to the future prospect for business. The change in policy will help in the betterment of the service provided by the organization to its clients. The agents of Sigma Global are advised to get approval of the material prepared for local marketing and advertising. As it is the most basic and initial projection of the organization to the local clients. Agents are warned and adhered to avoid unethical advertising and marketing to lure prospect clients. False information to the students will hampers relationship with the organization and is not acceptable at any cost. Agents should understand that we aim to guide the student and not to mislead them. It will result in Agents termination if found guilty of charge It had brought into our attention that our clients are finding it difficult to comprehend to the information on different services provided by the organization. To clear their misunderstanding it is necessary from our behalf to change the rules and policy to enlighten the student in a language that they would understand and comprehend best. Students are finding it difficult to understand the answer of few basic questions, which should have been clearly delta with by out agents. It is it important from our behalf to help the student choose the best university as per their need and preferences. To start with, agents should make the student comfortable and ask question regarding different aspect of their need and requirement. Agents should work on the soft skills and try to build repo with the student to understand their want. The inquiry should be conducted in a conversation manner so that it will make students comfortable and help them to easily interact and convey their requirement once that phase is cleared, the agent will now ask about the education qualification and would try to understand what the student want to pursue and from where. If the student have proper knowledge about the course and the institution he want to opt from the Agent will then ask related and relevant question to understand all the requirement o f the student and will try to suggest best alternative if needed. Agents are requested that student with no proper knowledge about courses and universities should be approached with calm and willing to help attitude as it will make them ease and help them open up. We want to make them understand that we are willing to help and shying away will hinder the process. Agents will ask these students about their aspiration and motivation and would try to figure the reason they want to study abroad. In addition, once the agent, relevant information about the course, understands it and university which will help accomplish the desired results should be provided. Agents are asked to provide information of the relevant universities and colleges offering the degree the student require as well as clear overview of all the other alternatives, the ranking of different universities as well as eligibility of different universities based on merit list should be made clear to the students from agents end. Agents are requested to ask question about financial stability and source of income from students to help them acquire the best university and accommodation facility whilst their stay abroad. Agents are requested to represent all the universities and colleges in equal and fair manner to the students, so that it would look like as a choice given to the student to choose upon. It will give the versatility to the student to determine the place and the university he would like to opt. Agents are request to make students understand that studying aboard is all about practical implementation and usage of the education. It is equally important from students behalf to look into the different recreational activities and co-curricular prospects given by different universities and fun learning sessions provided by the universities. Agents are informed that it is necessary to understand the need of students requirement about the stay and the option we have and can provide to the students. Accommo dation advice to the student should be accurate and must be exactly as promised. It is important that the expectation that they will have about the accommodation met as per requirement or else it will hamper the after sale service which will again lose us prospective clients. Agents are requested to inform students about all the facilities that can be availed from the organization and it is important for the agents to advice the students taking admission in the distant universities and colleges about the transportation facility which can be availed by them from our organization. Agents should let the students know that we are providing a substantial amount to every student to help them start in the new country, which can be utilized for the transportation allowance. The initial transportation fee will be given special discount of 20% if booked with the full amount of admission fee and rest of the expenses. Agents are informed that students need assurance about the university and the value of degree after completion of the course. It is necessary to provide proper information about placement cell and universities previous record of accomplishment agents should bring students attention about important rules and regulation, which needs to be mandated by the students in the country they will go for studies. Agents are warned again about providing false hopes, guarantee of permanent visa and work placement to attract the student is wrong practice, and Agent should avoid it. Honesty to build strong relationship with the students during the application process creates a transparency about the procedure. Honesty is a virtue and same is the motto of the organization so Agents should uphold companies values to its clients References Olaleke, O.O., Taiye, T.T. and Olumide, E.O., 2014.

Sickle Cell Disease Essays (513 words) - Hemoglobins,

Sickle Cell Disease The genetic disorder I was told to research was the Sickle Cell Disease. I will explain what mutation causes this disease, the characteristics of it, and what has developed in the area of gene therapy because of it. The Sickle Cell Disease is an inherited disease. The gene for hemogoblin-S (which causes the disease) is the most common inherited blood condition in America; although most people only inherit one copy of the gene for HbS, while the other gene, hemogoblin-A, is normal, and can override HbS, blocking the disease. These people have the HbS trait, but not the disease, therefore leading a normal life. For an offspring to acquire the disease, both parents must have the HbS gene, yet the child only has a 25% chance of having Sickle Cells. You cannot catch the disease, you are born with it and it is present for life. There are many complications and harmful effects as the result of the Sickle Cell Disease. The disease causes hemoglobin in the red blood cells, when it does not receive sufficient oxygen, to form into long, sickle shapes with a sticky, chemical surface. When blood cells are this form, they cannot go through the capillaries, blocking off both blood and oxygen. Fortunately only 20% of all red blood cells become Sickle Cells; the sickle cells have a shorter life span; and most blood cells go through the capillaries before becoming sickle-shaped. The most painful effect known from Sickle Cell Disease are episodes of pain called Sickle Cell Crisis, where the body is in need of oxygen, either from physical activities or a sickle blood cell blocking blood passages that lead to organs. The first day is the worst, where devastating pain goes to the arm, leg, and back, along with the shortness of breath. The other symptoms of Sickle Cells include: strokes, increased infections, early gallstones, yellow discoloring of eyes and skin, low blood cell counts (anemia), and delayed growth. For the cause of the Sickle Cell Disease, there has been many research going on in the area of gene therapy. Labs around the world are trying to fix the basic genetic defect, by placing the correct amino acid in the hemogoblin before or shortly after birth. This method would result in the cure of the root of the problem. Currently researchers are finding a safe way to perform this method. To try to ease the pain caused by Sickle Cell Disease, a substance that can prevent red blood cells from sickling without causing harm to other parts of the body, hydroxyurea was found to reduce the frequency of severe pain, acute chest syndrome and the need for blood transfusions in adult patients with sickle cell disease. Droxia, the prescription form of hydroxyurea, was approved by the FDA in 1998 and is now available for adult patients with sickle cell anemia. Studies will now be conducted to determine the proper dosage for children. The Sickle Cell Disease is a state of suffering, yet it is not as serious as it used to be, where children with the disease was not expected to live through childhood. Now with aggressive treatments, victims' lives are prolongs and improving its quality; and with the researching completed, a full cure of the disease can be possible.

Drugs and My Large Ass essays The Internets popularity has risen greatly in the last few years and its popularity has forced most industries to go online. The Internets millions of users have attracted commercal banks. People are increasingly using the Internet for financial services in addtion to using the Internet for research, education, The last few years have seen an explosive proliferation of the Internet, with millions of users around the world logging on for a growing number of purposes. People shop, research, take classes and file their taxes on the 'net, and, increasingly, are using online banking services to manage their personal finances. Personal computers, telephonic banking and increasingly sophisticated automated teller machines are becoming commonplace as consumers abandon daily or weekly trips to their local bank branches in favor of more convenient electronic financial service. Although consumers appreciate the speed and convenience of electronic banking, there is growing concern over the security of Internet transmissions. H.R. 2937, for example, provides for the recognition of digital authentication in place of signatures, a move that has supporters praising the technological savvy of the banking industry, but leaves some critics deeply concerned at the possibility of misuse by criminal hackers. While ATMs are a more "secure" form of electronic banking, consumers are paying in other ways. Fifty-four percent of the nation's banks add surcharges for the convenience of using the ATMs of their competitor's banks, and many independent ATMs operated by non-depository institutions are charging fees as well. Critics, led by Sen. Alfonse D'Amato, D-N.Y., are calling for a ban of these surcharges, saying that banks are profiting by "gouging" customers with outrageous fees. Others argue, however, that banks make little or no profit off the surcharges, and that independent ATM ...
