Motor Efficiency Practical - Physics - 1550 Words

Stage 1 Physics – Practical Aim: To calculate the weight limit held and the efficiency of an electric motor. Method: 1.) With all materials gathered, start by plugging the Power Supply Unit (PSU) into a free plug, making sure the PSU is switched to 6V. 2.) Attach the Crocodile clips from the PSU to the ammeter and motor as shown above in the labelled diagram, making sure the voltmeters clips are attached to the motor. 3.) Starting with 20g of weight attached to the string on the motor (as seen above) perform 3 experiments with each weight group (20g, 40g, 60g, 80g) and record their voltage, time and current. 4.) Have one person reading the ammeter, one person timing the weights reaching the top of the motor, and the†¦show more content†¦There are many sources of error that shouldn’t be ignored throughout this practical exercise. Stick to the safety instructions to ensure maximum protection to both the devices and the students. Analysis and Evaluation: (real life motor efficiency situations) The initial task was aimed to test whether the motor could life a range of valued weights between 20 grams and 100 grams. Whilst testing the motors capacity to hold certain weights, an input and an output formula were used to calculate the efficiency of the motor. This was relative to the Voltage, Current, time, gravity, height (string off the ground) and the mass of the weights. Fortunately each of the three sets of four given weights was successfully lifted by the motor across a variation of times. This data also changed the readings on the voltmeters and ammeters. The results that were calculated along with the efficiencies were both successful and astounding to come across especially as the graphs trend above goes up and down, rather than in a single direction. On a larger scale, the example of a Lego made motors efficiency can relate to that of a modern day car and the efficiency / energy waste that comes from it. The internal combustion engine is an engine in which the combustion of a fossil fuel mixes with air in a chamber of the operational fluid flow circuit. In an internal combustion engine, the development of high temperatures and highShow MoreRelatedUse Of Electricity And Its Effect On Our Lives955 Words   |  4 Pagesimprove our lives.

Pro Clean Free Essays

Company overview/ Statement of Problem Pro Clean LLC is an old-timer carpet cleaning business. It was owned and managed by Kevin Wilson and located in Knoxville, Tennessee. Wilson had to manage almost all functions of Pro Clean daily activities. We will write a custom essay sample on Pro Clean or any similar topic only for you Order Now In this industry, the problems Pro Clean faced are how to stay competitive and still make above average returns with one of his main competitor the King Rug. King Rug has a resolute business structure and is able to charge its customers with high prices which make King Rug much more profitable than Pro Clean. Another problem that Pro Clean has to face is the rapid expansion process. At the onset of the expansion, the business had started to churn cash as a result of the increased payroll expenses and the lease payments for the company’s vehicles. Wilson’s return on investment was dismal. Cash flow quickly became a problem and Wilson resorted to using his business and personal credit cards to finance his business. Environmental Scanning/ Stakeholder Analysis Demographics of Pro Clean are composed mostly of customers from Knoxville, TN. Being located in the Suburban district and close to Condominiums near the City Center; most of its customers come from single-income families, above $250,000 annually. Most of these homes had pets/ young children. 20% of the business made up of the regular customers. Economically, Pro Clean is doing fine with its source of Revenue made up of cleaning carpet (77%), upholstery cleaning (9%), area rug cleaning (5%), tile and grout cleaning (5%), carpet and fabric protection (3%), and drapery cleaning for (1%). The culture of the customers of Pro Clean is those of frequent use. Average Pro Clean customers had their carpets cleaned every 12 months. Technologically, Pro Clean had improved from stuffing envelopes with direct mail material, answering phone calls and giving estimates to setting up a webpage so customers can easily and instantly know about the company’s profile and service. Pro Clean is just a local business thus it is not thinking about expanding to another country, however, it sought to expand locally with much difficulty Industry Analysis Pro Clean’s NAICS code is 339994. According to the United Census Bureau, a 339994 is a â€Å"Broom, Brush and Mop Manufacturing† Pro Clean conducts a pure competition in where there are many other competitors selling similar ervice in the industry. Its main competitors are D-Clean, King Rug, Green Clean, Right Clean and Kleen Clean. The industry is a growing market. The market grew approximately 5 percent per year, which was what Wilson’s business averaged as well. Currently, Pro Clean had built up a respectable 5 percent market share in Knoxville Now for Porter’s five forces model of Pro Clean, they are very weak to withstand the threat of new entrants because a number of national janitorial cleaning and carpet cleaning chains were advertising aggressively to establish new franchises in the city. The bargaining power of supplier of Pro Clean is rather weak. For a cleaning company, Pro Clean can pretty much buy their source of cleaning products pretty much from different suppliers and switch products without hurting the company’s balance sheet. The bargaining power of buyers of Pro Clean is rather weak also, because the customer can switch to another cleaner company in town where it might have a service which Pro Clean doesn’t have. In addition, there are approximately 60 cleaners in town competing in the same industry as Pro Clean. Substitute products are a huge disadvantage for Pro Clean. Some new customers who are not used to carpet cleaners preferred to buy the cleaning products and do the cleaning by them. The commercial cleaning market was serviced by janitorial service providers that offered a one-stop service to commercial businesses which Pro Clean does not offer. The intensity among the companies is cut throat. The market is very competitive because the firms have similar service and almost equal status among buyers. The other companies are killing each other to differentiate themselves from their competitors by conducting additional source of revenue. For example, King Rug derives a substantive portion of its revenue from rug cleaning at its place of business and did well with cross selling and up-selling. Pro Clean however, did not successfully up-sell Company Analysis Pro Clean vision is to be the number one carpet and rug cleaners and â€Å"ready to take on even the best in Knoxville† Pro Clean’s mission to accomplish this vision is to â€Å"stay in touch with all its customers by sending out quarterly newsletters. † The current goal of Pro Clean is to organize their organizational structure where it had inaccurately expand too fast and thus hurting company’s current cash flow. To achieve this goal, Wilson had to lay off one of his cleaning technicians. He temporarily transformed the cleaning technician position to that of sales and office administration. Wilson had to spend his personal time trying to develop the business as well as dealing with administrative and clerical tasks. SWOT ANALYSIS Strength: 1. Pro Clean has 5% overall market share of Knoxville carpet cleaning market 2. Its market shares grows at 5% annually 3. Their business venue is located in the city northeast residential district (most of its customers are residential people) 4. It has loyal customers which generates 60% of its income Weakness: 1. It has a poor organizational structures 2. Lower price charged to its customers making it to have difficulty covering overhead costs 3. It expanded too quickly, making a small return on investment. Opportunities: 1. Pro Clean might be able to target not only residential areas but also commercial as its main competitors do not target commercial areas 2. Pro Clean continue charging a lower price than its main competitor in the rug cleaning business Threats: . Pro Clean competes in a highly competitive market 2. Other companies might crush Pro Clean by offering a cheaper service fee 3. Any frequent-customers who suddenly become unsatisfied might turn its revenue down. Pro Clean’s philosophy is that â€Å"each and every client is the most important facet of our company†. Pro Clean’s core competency is its ability to make on-site estimate visits, while other competitors gave approximate estimates ov er the phone and followed up with a detailed price once they were on site to clean. Porter’s value chain of Pro Clean is important to the health of the company. Their network (existing customers, technology and follow ups) are the most crucial in the relation of its income statement. They must keep on doing whatever they do best not to lose any existing customers otherwise the company’s operating income will suffer. STRATEGIC ANALYSIS The corporate strategy of Pro Clean is at a low level because it does not conduct any other form of business other than cleaning services. It has a cost-leadership business strategy as compared to its main competitors; it charged the least fee for cleaning services. Pro Clean ability to keep its existing customers is certainly a positive effect on the company’s image and it also can give a positive â€Å"free advertisement† to these customers’ relatives. The culture of Pro Clean is that the human resource works as a close knit team. While Wilson is out, his employees will routinely visit real estate agents and other referral sources for half of the day while others spent the remainder of the day in the office. ALTERNATIVE/SOLUTION The two main problems mention above is the significantly low pricing which makes it unable to cover its overhead costs while its main competitor can; and the other problem is the wrong decision of the expansion which was rather too soon for the company to handle. The main opportunity which Pro Clean might be able to consider is that it should aim for not only residential area carpet cleaning but also commercial area as it will hugely increase the number in their sales. Also, I believe that the expansion has already happened but it produces a little, if any, a positive return on investment. The way I would take advantage of this is to either sell the extra capacity/ plant or to maximize its ability to produce different product/services which might be able to generate more revenue for Pro Clean. For example, not only they do the cleaning business, but they also manufacture their own brand of Pro Clean cleaning products. I believe that Pro Clean can survive if these problems were to be exploited. With additional capital and better company strategies implications, Pro Clean will be able to dominate the cleaning industry locally. End Note Page How to cite Pro Clean, Essay examples

How important is next day air shipment to the customer experience?Is it worth the cost? How might you change it in the cost-conscious environment facing the company in late 2008? Offering rapid delivery at no additional charge is a good way to provide exceptional service to WOW customers. Capos always try to beat customer potential, under-promising and over- delivering. Ultimately, this meant operating the warehouse in the evening would usually be delivered the next day, even though the standard delivery arms were for UPS ground, which had a 4-5 day delivery expectation.The customer experience regarding this shipment which delivers their products to them only in one day is awesome and they feedback wow to the company. However, when Capos guaranteed next-day delivery for all orders during the 2006 holiday season and 2007, customer satisfaction reduced. Since they expect the delivery to arrive in the next day, they were no longer as wowed as before, when it was a surprise upgrade. Furthermore, guaranteeing next day delivery set customers up for disappointment on those rare occasions when the deliverance was late due to inevitable problems.So Capos decided to no longer promise the next delivery, but still offer the same service. Customer satisfaction increased again as they receive their shoes earlier than they expected. As capos continued to increase delivery speed, shipping cost as a percentage of net sales remained constant. And by 2008, capos was one of the top three UPS overnight shippers. In this case, Capos is able to get more satisfied customer and more word of mouth, with the expectation of sales increase.The next day air shipment seems to worth the cost. In 2008, customers become more price conscious because of economic down. If capos decided to back off from its desire to ship all orders for overnight delivery, for instance, using ground delivery for all customers that Were within a twit-day delivery from its warehouse, it estimated that savings could be significant. As we can see in Exhibit 5, Capos have a very high level of gross margin(35%) but relative low operating income (3. 4%).If we reduce the cost of overnight delivery, we can expect the operating income will be higher. In addition, because customer are so price-sensitive in 2008, Capos might want to save the cost from overnight shipping and may be WOW its customer with some price related strategies. For example, a lucky price reduction after a customer has purchased an item or a lucky voucher shipped with their shoes for next purchase. 3. How would you expand the business? Would you add more product, more geographies, or by selling private labels?As you expand the business, how can the company become more profitable, particularly in light of the costs associated with the focus on service? Considering the challenges faced by capos in 2008, I would recommend capos to add more products. So Capos will expand the business still giving a best quality to the customer with the immediate speedy delivery, superior customer service for better feedback. There are 4 reasons why I think Capos will succeed by selling more products like cloths and accessories.Brand equity and customer base: Capos has successfully built a positive brand image among customers with a large customer base (about 3% of US population) Evolutionary operation system and other inventories like call center : This system is one of the most completive advantages Capos have developed. It enabled Capos to deliver WOW not only to customer but also to brands and its employees and keep the cost low at the same time. The culture of Capos The experience learned from doing shoes business. Recommend the following investment in order to expand with new products.There will be some additional cost occur to Capos, but they are expected to be covered by higher revenue. Recruit people with experience previously on expanded products like cloths and accessories. They need those new people both on operations and call center services. The right people will help capos to find good products and brands and forecast demand. Also, capos need to hire new people and train old people in call centers, so that customer will be ell served when they have some questions about closes or accessories.Adjust their operation and inventory system to satisfy the need of managing new products. Although the new products will be in fashion industry just like shoes, the requirement for categories, stock and inventory are slightly different. Capos need to invest to make their existing system serve the new products. In this way, they will maintain a great customer satisfaction level at an lower average cost level because of scale of economics. They need to redesign the website and maybe insert a recommender system in order to aka a more convenient customer shopping experience.For example, if a customer chose a pair of shoes of certain style, capos may recommend a dress to match that shoe. In this way, we expect some old customers from shoes will switch to cloths as well. However, the recommender system can be complicated and expensive. In order to provide a superior customer experience, I recommend capos to provide some unique service to help customer to choose the right size online. For example, it can provide a service that members can fill in all the measures of their body, and the system will commend the right size for s/he based on the data they get from manufactures.In this way, the return rate is expected to decrease significantly. 4. How would you expect the environment of a more cost-conscious consumer to affect Capos business? What can Capos do in such an environment to maintain sales growth? Capos has the feedback facility to allow customer to write their review and comment. If the cost-conscious consumer are not satisfied with the price, we can tell from those feedback. If a lot of cost-conscious consumer stopped shopping at Capos, we can tell from the total sales.
