Technical report on the Trolley Jack. Technical report on the Trolley Jack1.  Ã‚  Ã‚   Introduction In this report, several aspects of trolley jack shall be discussed. These include a description the product or what it is, how it works, health and safety issues surrounding the machine and its components. The report shall also include the design criteria, methods of manufacture and product comparison. In this comparison, the product shall be considered with reference to other similar products and also its cost against the quality and functionality of the product. Towards the end of the report, a review of the whole report shall be done and general observations made. At the end, references from which information was researched shall be outlined. 2.  Ã‚  Ã‚   Product Description According to Corneilse, Marr, Mogotsi and van der Hee (2007), a trolley jack is a portable piece of equipment that can be used to raise one side of a vehicle for instance when one wishes to change a vehicle tyre. It has been found out that an average trolley jack can lift a mass of up to slightly more than 2 tons. A single stroke of a trolley jack raises a load to for about 4 inches which is sufficient for trolleying. This trolley type can lift up a load for a maximum of 15.5 inches. It is thus appropriate for robust jobs yet it is relatively affordable. 3.  Ã‚  Ã‚   Trolley Jack design and manufacture As the name suggests, the jack has properties of a trolley in that it can be pushed along courtesy of its wheel and two castors. The body of this device is made of steel (heavy-duty). The reason for the use of this metal is because of its tensile strength: It does not twist or bend easily. So as to calculate the cost of manufacture of trolley jacks, quantity is a key consideration. This is because the larger the quantity is produced, the lower the average cost of manufacture (Tooley, Tooley Dingle, 2004, p. 34). Therefore the average cost of manufacture is the total cost divided by quantity manufactured. 4.  Ã‚  Ã‚   The Components of the Product As earlier stated, some of the parts of the device are the saddle and the release pedal. Other parts include a wheel, two castors, the lifting arm, control handle and the main body. The wheel and two castors are essential for its movement while the lifting arm is useful for making strokes. The main body covers the mechanical system that raises loads. 5.  Ã‚  Ã‚   How it works The Automotive repair and maintenance: Level 2 stipulated that a trolley jack uses a hydraulic system to raise a vehicle. To do so, a saddle is placed under the vehicle in the correct position. According to Keeting, Sutton and Abrahams (2008), the next step should be to block the wheel so that it does not roll. The vehicle should be on the handbrake. Thereafter, a control handle is used for raising the vehicle after which it is worked on. However, after lifting for some height, the user should check whether the jack is still in its position. Safety stands or axle stands should then be fixed for safety purposes. Later, a release pedal is used to lower the vehicle. 6.  Ã‚  Ã‚   Comparison with other products’ quality, cost and functionality In view of most technical experts, all what is considered in jacks is how high or low the device can lift for example a car. Therefore, a good jack should provide a maximum lift for to a vehicle so as to have maximum space for work. Another aspect on the functionality of the product is how fact it can work that is the number of pumps needed to reach the highest level. Additionally, functionality is based on the maximum weight the device can lift. Bearing in mind that there are many aspects which could be considered in rating jacks in general, when the above were considered in one of the investigations, the following types were rated to be the best in this order: Clarke CTJ3000QL, JCB70003 and Kamasa GE4841. An average Trolley Jack produced by KarKare costs about 45 Sterling Pounds. According to Tooley, Tooley and Dingle (2004), the company produces about 12,000 units of trolley jack. Another type of Jack called Ellis Jack or Cam-type jack at most 6*6-inch timbers placed side by side and joined by steel champs. 7.  Ã‚  Ã‚   Health and Safety Issues when Using the Trolley Jack In their Fundamentals of technical rescue, the International Association of Fire Chiefs and National Fire Protection Association (2009) cautioned that when a technician is carrying loads on a jack, they should ensure that the load does not shift. This is because uneven distribution of weight can make the device to tip over and fall thus endangering the health safety of the user. In addition, whenever one is using a trolley jack, they should ensure that it is placed on a flat surface. The surface must also be hard so that it does not give way when a heavy load is being lifted. Therefore if the surface is soft, it is important that the user places a hard board or a steel plate under the jack for an even distribution of weight. It is also important to note that with regard to vehicles, a trolley jack should only be used to lift the vehicle but not to hold it place. One must use jack stands whenever working beneath the vehicle to avoid being crushed incase the device loses grip. When jac king a vehicle, one should block its wheels so that it does not roll. A tire should never be changed on a highway. 8.  Ã‚  Ã‚   Conclusion and general observations This technical report was meant to describe some aspects of the trolley jack. This was successfully done through an initial outline of the way themes were to be tackled. Thereafter, the description of the device was done followed by its design and manufacture, its parts, how it works and some of the safety and health issues associated with its use. Later, the device was compared with other similar devices in terms of its cost, quality and functionality. It was clear that the product is relatively affordable and can do heavy jobs. Although the trolley jack is generally efficient, it was observed that the hydraulic models are usually slower particularly when being lowered. It is thus satisfactory that heavy jacks should be used with heavy vehicles such as Lorries and buses in which speed is not of great importance. References Corneilse, M., Marr, S., Mogotsi, S.

Linear Motion In One Dimension Lab Report Example | Topics and Well Written Essays - 500 words

Linear Motion In One Dimension - Lab Report Example All freely falling objects experience a downward acceleration. Using the symbol g to represent such special acceleration, the value increases with decreasing altitude. The value of g is around 9.8 m/sec2 at the earth’s surface. Because friction is neglected and the assumption is made that the free fall is not dependent on altitude over short distances, the motion of the freely falling objects is equal to the motion in a single dimension under constant acceleration thus making it possible to apply constant acceleration equations. The recorded coefficient r values are both close to 1 indicating that the plotted points are closer to the experimental values. As per the recorded values, the increasing x values had a positive gradient whereas the decreasing x values had a negative gradient. Therefore, it is true that X increases at a constant rate with time, hence equation 1 is justified The velocity after the bounce was higher because of the impulsive force exerted on the glider at the track’s end. Again, the recorded value of acceleration is reasonable because the velocity is reversed at the track’s end meaning there was a moment when no acceleration is acting on the glider. In the inclined track, the glider was observed to move under a constant acceleration before or after bouncing and this is in harmony with equation 1 which states distance has a direct proportion to the square of time. The slope of velocity against time line matched the previously calculated acceleration value. The slopes of the velocity time graphs in the inclined track with the six blocks also matched the earlier on calculated acceleration value. The trend observed in the all the three cases validates the linear motion equations. An analysis of the drawn graph gives acceleration values that are consistent proving that constant acceleration equations can be used in describing linear motion in one

Circumstantial Evidence Within The Casey Anthony Trial Research Paper

Circumstantial Evidence Within The Casey Anthony Trial - Research Paper Example did not merit proving the case of intended murder of Caylee beyond reasonable doubt, it is evident that the prosecutors had adduced evidence that had sufficiently served the principle of ‘reasonable doubt’ as a requirement of the law (Sarokin, 2011). Circumstantial Evidence is the important piece of evidence in criminal cases prosecution, owing to the fact that only a small percentage of crimes would be executed out of existing direct evidence. If all cases were to depend on direct evidence where a witness was present when the accused committed a crime, only a meager criminal file cases would even pass for trial (Fanning, 2009). After all, what would hinder the defendant denying being involved even when the witness still witnessed the crime being committed? In this respect, Circumstantial Evidence is vital for criminal trial, since it provides for the relevant pathway through which reasoning can be applied, so at to reach to a conclusion regarding how the crime was committed. The Casey Anthony Trial appears to have deduced sufficient circumstantial evidence, only that it was not executed properly. First, false testimony that Casey gave to the law enforcement officers when they set on investigating the case is sufficient to indicate that the defendant was determined to obstruct the course of justice (Ashton & Pulitzer, 2012). Despite the fact that reasonable doubt as a basis of determining the guilty or not guilty verdict for the accused is a necessity, nothing could be more indicative of the fact that the defendant must have known something about the death of Caylee than the false statements. Therefore, Casey was lying so that she could obstruct the law enforcement officers from being able to conduct a fruitful investigation. Casey had lied to her mother that Caylee was either with a nanny, in the beach, in the house and a host of other places for the whole time that her grandmother was asking for whereabouts (Russell & Cohn, 2013). Additionally, Casey lied

Philosophy of Counseling Essay Example for Free

Philosophy of Counseling Essay The purpose of the school counseling program is to guarantee academic, social, and professional success among all students. School counseling is s collaborative relationship between students, school counselors, teachers, parents, administrators, and the community. Through these partnerships, the counseling program will develop a support system to enhance student achievement and promote growth of future productive citizens. The role of the school counselor is very active. School counselors must be an assertive advocate by creating opportunities for all students to foster their dreams and achieve their goals. A dedicated counselor plays a major role in the school through research, data, collaboration, individual counseling, group counseling, career planning, and caring for the students overall well being. The school counselor serves as a leader and team member; working with parents and school personnel to make sure that each student succeeds. Human nature can be viewed as all individuals are considered equally good. People are creatures of habit and learn from their cultural upbringings and the ones around them. Now days, students deal with poverty, single-parent households, thoughts of suicide, neglect, abuse and so much more. In this complex society, it is necessary to provide learning experiences which will empower the child to overcome life challenges and set achievable goals. Goals can be reached by change. I feel an individual can change through awareness and influence. Students have to want to change and be aware that there is a need for change. The role of the professional school counselor is to support and influence the student. Change is achievable by tracking data and giving constructive feedback. The counselor will assist student in their academic, social, emotional and personal change and help to decide the best ways to successfully achieve their goals. Disaggregating data is the foundation for the school counseling program. The use of these resources will track student progress and provide evidence for growth. Data also helps the school counselor understand what is and is not working in the counseling program. If a student is not successful then we are not providing the correct interventions for that particular student. The changing needs of students, families and schools require professional school counselors who are current with new counseling programs. These programs must focus of students academic, career, and personal/ social needs. I feel as society changes that the students are setting the new goals for the counseling program. It is essential for the school counselor to foster and set realistic achievable goals for the student.

Kaleidoscope Essay -- Descriptive Essays

Kaleidoscope â€Å"Some are transformed just once / And live their whole lives after in that shape. / Others have a facility for changing themselves as they please.† -Ovid It finds its way into my hands—the small kaleidoscope—a trinket my grandfather passes along to me after finding it at the bottom of his toolbox one afternoon. â€Å"Hold it up to the light, Lauren,† he advises me, upon witnessing my attempts to unlock the kaleidoscope’s magic by aiming it towards the shadowy pavement. With hands clasped, eyes squinted, and head cocked, I finally spot the colored chips, a glittering lattice of blue, green, and yellow, stagnantly arranged and defined. â€Å"Turn it, now,† my grandfather orders, smiling. Suddenly, the clear composition unravels. It becomes a moving color war, triangles and rectangles interacting, skirting around one another to form patterns that linger only fleetingly before changing again. I gasp, intrigued. â€Å"That’s the beautiful part,† my grandfather observes. â€Å"It’s beautiful when it’s turning.† The challenge of cleaning out my desk drawers in preparation for the move to New York results in my stumbling across an old coloring book. I leaf through the pages, startled by the number of pictures I’d left only partially colored. With quick, shaky movements, it seems as if I had simply jumped from shading one image to the next, as if there were something complete about leaving the figures incomplete. Sitting at my desk, fourteen years older, I laugh at my rendition of Big Bird, whose characteristically yellow feathers I had made blue and whose feet (I suppose I had decided) were altogether undeserving of color. And yet I get a sense that thi... ... of wholeness, but the acceptance that I’ll always be a work-in-progress that creates the satisfying illusion of completeness. Although ignorant of his own words, my grandfather has gotten it right: It is beautiful when it’s turning. We, as human beings, are not able to ossify what we perceive to be our â€Å"identity†; it will be forever changing—a kind of surreal, confounding, and complex reflection of our human experience. We possess innumerable facets, like little tubes of color that remain separate until some creative force removes all the caps and mixes them together. It is that mà ©lange that initiates a masterpiece of identity—a masterpiece that is ever changing and never quite finished, but fulfilling in its progression. And it is precisely this understanding that makes the next stroke of the brush a little bit clearer, the portrait itself a bit more revealing.

Skinhead and It Fashion Codes

Skinhead subculture is originated among working class youths in United Kingdom in the 1960s. The first skinheads were greatly influenced by Jamaican rude boys and British mods. Originally, the skinhead subculture was primarily based on elements of fashion, music and lifestyle, not politics or race. However, with the revival of skinhead in 1970s, the emergence of white power skinheads made them largely related to race and politics. Today, I will explain the skinhead identity by showing two clips from Romper Stomper and my partner Silvia will introduce different factions and politics of skinheads as well as their condition nowadays. Clip ] This clip presents the conversation between Hando and the woman in his room, illustrating his main purpose of becoming skinhead. Hando’s life as a skinhead is largely related to Nazi. As showed in the film, his room is decorated with a great number of Nazi objects including the Nazi helmet, posters, flag, book and tattoos on his body. The neo- Nazi culture commodities are used as subcultural capital, which is expected to raise their status and help differentiate themselves from others.However, audience of mainstream will interpret these subculture capitals as strange, deviant things and hence regard skinheads as a subculture which cannot be accepted by the mainstream culture. Although not clearly indicted in the film, the activities of these skinheads seem to be depicted as deviance that violates social norms. The first clip we intensively represents the deviant image of skinheads through scenes such as using violence to the Asians, and close-up of their unusual living place.Deviant acts can be a way to predicate identity, thus against norms of the dominant culture and in favor of a subculture. Fashion The identity of skinheads can be also maintained through fashion and music. Fashion is an essential element to distinguish skinheads’ identity not only from that of mainstreams, but also from different factions. Thro ugh fashion, skinhead groups form unique resources for individuals to project an image and hence achieve their identities. Skinheads are visually identified by their short hair and unique clothing styles.Although various factions of skinheads may have tiny differences in dressing, they all conform to a general dressing style which includes braces, fitted jeans, ‘sta press trousers’, button-down shirts, polos, boots, and flight jackets. Moreover, skinheads favor of several brands such as Ben Sherman’s button-down shirts, Fred Perry’s polos and Doctor Marten’s boots. The choice of particular fashion items is orchestrated by skinheads to reflect their collective identity. Furthermore, skinheads also use fashion to distinguish between factions.For example, several skinheads use different color laces in their boots to show their political identity, or stance on race. White laces refer to white power skinheads, red laces stand for communism and a combinat ion of yellow, black, and blue laces refer to anti-racist SHARPs. In addition, tattoos are used to identify different affiliations. Number 69 can be found in those who pay homage to the peak of 1969 of skinhead subculture, while nazi symbols can be found on those racist skinheads.MUSIC Music is another critical aspect for skinhead identity. Traditional skinheads were heavily impacted by Jamaican ska and reggae music. In 1960s, skinhead music was labeled as ‘skinhead reggae’ by record companies. Some bands such as Charmers, Desmond Riley were singing about skinheads. Thus, this early music reflects the clean cut fashion which is indicative of skinhead style. In 1970s, the emergence of Punk music not only drew skinheads’ attention, but also the mainstreams.Since many skinheads label themselves as the periphery of mainstream culture, a new form of punk called Oi emerged to uniquely express skinheads’ frustration and ideology. Similar to fashion, difference co uld be found in various factions’ Oi music. For example, racist skinheads’ music can be easily distinguished because the themes of their songs are racism, largely differ from others. That’s the end of my part; let’s welcome Silvia to introduce the factions and politics of skinheads and their condition nowadays. http://v. youku. com/v_show/id_XMzIyNTQ0ODI4. html

Discrimination Is Still Very Much Alive - 847 Words

He s capable of more than just transferring the residents to their rooms! He can take care of anyone just as well as you can! screamed my teacher to the head nurse. I was in a nursing program that only accepted ten students, only one was a guy. We trained in a nursing home and had to feed, change, and bathe the residents. He was assigned to assist a male nurse who was only allowed to help the residents move because he was the only strong one of the group. Apparently he wasn t gentle or caring enough to help with anything else. He missed out on the learning experience that this program was suppose to give him. This was the first time I ve witnessed discrimination in the workplace. I was completely disgusted to say the least. I realized that discrimination is still very much alive and it doesn t only affect women, but men too. I grew up to my mother telling me about the many times she was treated badly for being a Hispanic working woman, so typically when I hear about discrimination I think of race or gender. I think most people assume the same thing. When in reality it s much broader than that. Job discrimination is when someone is being treated unequally as everyone else because of their race, sexual orientation, religion, disability or even age.
