CHAPTER I

INTRODUCTION

Listening to the hum of a washing machine turning a dirty load of laundry into clean clothes, it's hard to believe a washing board was once considered a modern convenience. Washing machines have come a long way since their invention and some new, high-tech versions are changing the way people do laundry.

As technology invaded the world of mankind, people continued also to find alternatives to lessen the effect of using such kind of technology as a useful process of every life. The researchers find out that this electronic, heavy, place only in one position washing machine will transform into like a portable machine. This washing machine turned into a habit of exercise as if someone is making a round of a trip by using a pedal powered washing machine.

The first washing machines appeared in the 1760s. These were commonly a wooden box that was filled with clothes and rotated by hand. In 1874, another invention appeared a machine that used pegs and gears to push clothes through soapy water. In 2001 Electrolux introduced Washy Talky, the washing machine that speaks to you with such memorable phrases as "drop the detergent, close the lid and relax." And now there is Pedal Power Washing Machine. Pedal power is the transfer of energy from a human source through the use of a foot pedal and crank system. This technology is most commonly used for transportation and has been used to propel bicycles for over a hundred years. Less commonly pedal power is used to power agricultural and hand tools and even to generate electricity.

Statement of the problem

This study aims to determine the advantages and disadvantages of a pedal powered washing machine in terms of the lifestyles of the consumers, the cost, and the effect to the environment.

It sought to answer the following questions:

1. What are advantages and disadvantages of using pedal powered washing machine?

2. What are the factors to considered of the consumers to the lifestyle, cost and to the environment?

3. What make it relevant to use pedal powered washing machine over ordinary washing machine?

Scope and delimitation

This study will focus on the design of the pedal powered washing machine. This will prioritize the relevance of using the pedal washing machine over the ordinary expensive washing machine and how this will be take part in the everyday life of the humankind. The research will delimits the involvement of money, materials, and to the environment.

Hypothesis of the Study

The researcher’s speculations for the outcome of the study are:

1. Transforming used bicycles into pedal powered tools is a sustainable development.

2. Riding a bike can have more benefits than simply exercise or green-transportation that helps our ecosystem as well as the consumers.

3. This pedal powered washing machine is a great cause to mankind in terms of cost, wellness and so on.

Significance of the Study

This study will benefit the environment and lots of people especially those who use the pedal powered washing machine. This pedal powered washing machine has less cost than an ordinary washing machine drive by the electricity while this pedal powered it gives motivation to the consumer for promoting the good health as well as it promotes the friendships with our environment. It helps to recycle rather than to throw them.

Definition of Terms

This part contains the definition of terms used in this study. The terms were defined functionally, operationally, and conceptually in order to give readers a clearer and more understandable view of the topic.

Washing Machine- is a machine to wash laundry, such as clothing and sheets. The term is mostly applied only to machines that use water as opposed to dry cleaning. Washing entails immersing, dipping, rubbing, or scrubbing in water usually accompanied by detergent, or bleach.

Plastic - material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances.

Bracket- A decorative or weight-bearing structural unit, two sides of which form a right angle with one arm flush against a wall and the other flush beneath a projecting surface, such as eaves or a bay window.

Freewheel- a device that allows a bicycle wheel to revolve forward while the crank is stationary.

Machine- an apparatus using or applying mechanical power and having several parts, each with a definite function and together performing a particular task.

Motor- a machine, esp. one powered by electricity or internal combustion, that supplies motive power for a vehicle or for some other device with moving parts.

Pedal- A foot-operated lever or control for a vehicle, musical instrument, or other mechanism, in particular.

Pulley- a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.

Schematic- is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures.

Review of Related Literature and Studies

Related Literature According to India: Land of a Billion Entrepreneurs, A pedal-powered washing machine, a bicycle that runs over water as well as the road, a low cost milking machine that works on the principle of vacuum suction, an electronic walking stick that cannot be stolen, a three wheeled-tractor that uses less energy, a windmill made from bamboo and groundnut pod machines are among them. Creative Thinkering: Putting your imagination to work, said that combining “bicycle” with “washing machine” created a human-powered washing machine: an exercise bike with a lithium-ion battery that collects energy as you pedal is wired to the front-loading machine. When you pedal, you power the machine. Twenty minutes’ effort is said to give you one cold-wash cycle without drawing power from the grid. From the design for Society, stated that a pedal-powered washing machine can still constitute an advance, and the prospect that in the future washing machines with electric motors may be available to washer-women, shows the includable gulf that exist between the affluent, industrialized countries.

From The Human-Powered Home: Choosing Muscles over Motors, mentioned that for some reason people interested in human-powered devices are especially attracted to the idea of making a pedal-powered washing machine. Maybe it’s because both rely on rotary motion, making them seem like an obvious pairing. Or maybe because it’s a washing machine appears to be simple thing to construct or modify, or because doing laundry is an elemental chore that until recently in our evolutions have experimented with ways of combining bikes and washing machines, and several designs have resulted.

From Design for Environmental Sustainability, said that the project was created to react to the local demand and its first objective was improving the working conditions, which cause serious back problems and pains.

Related Studies

Pedal-powered washing machine is designed for all the consumers who don’t have enough to buy expensive Electric washing machine, and to promote health wellness to everyone who uses it.

Bicilavadora Stated that a low cost, pedal-powered washing machine that is designed around readily available parts. Its innovation is its simple design and its use of inexpensive plastic barrels and bicycle components. The Bicilavadora is reliable, easy to operate and uses no electricity. The parts are available locally, so Bicilavadoras can be manufactured and repaired in the community without depending on imported goods.

MIT's pedal-powered washing machine The product of four years of research, is made up of a bicycle frame, a bicycle chain and oil drums--all items that are inexpensive and easy to find. A prototype of the washing machine was built in 2005 by Radu Raduta, a mechanical engineering graduate student at MIT. After winning first prize for her design in the MIT IDEAS competition, Raduta received funding to continue work on the machine. Construction of the pedal-powered washing machine is relatively easy. An oil drum is cut into sections and welded together into a small barrel. A smaller inner drum is rotated during wash and spin cycles, and the whole thing is powered by a wheel-less bicycle frame.
GiraDora
A combination of washer and spin-dryer powered by a foot-pedal. Designed specifically for those with the least income living in the poorest nations, the GiraDora hopes to ease the burden of washing clothes. The portable plastic tub can be filled with soap and water before a lid is placed on top, acting as seat. Then all the user needs to do is rest on the washer, and pump the spring-loaded foot-pedal.

State of the Art The researchers has only one purpose even the past invention of this machine has only one purpose, to help the consumers and also the environment. The design is a Top-Loading kind of washing machine while the others are front loading which is more rare invention than top loading. The pedal powered washing machine is a low cost and aimed at saving electricity and it is design around readily available parts. It is a bike where you can burn calories to clean clothes. The Pedal-Powered Washing Machine is made up of recycled plastic drum and bicycle is the most important part for these are the main objects of the design, a 20 gallons of water is the maximum capacity of the drum and 1 kilo of clothes and sheets can occupy the drum. This design is to lessen the burden to wash the clothes of every consumer and just gain muscles instead. In todays’ time a lot of people are not aware of their health because there are so many invention that will help to lessen their chores but they don’t know is that they are becoming unhealthy and lazy.

CHAPTER III

RESEARCH DESIGN

This chapter presents the overview of the design of the mechanism used in this study.

METHODOLGY

This study used the applied method of research. Scientific study and research seek to solve practical problems. As defined at slideshare.net, “applied research is used to find solutions to everyday problems and develop innovative technologies, rather than to acquire knowledge for knowledge’s sake.

The aim of the research is to construct a design for the elements of mechanism of an improvised washing machine by applying human power to rotary motion.

STAND ASSEMBLY

The stand described here is to support the bicycle to be rigid.

Materials
12 ft. (3.7m--3/4"(20mm) angle, 1/8"(3.2mm) wall thickness
8ft. (2.5m--1/2" (12.5mm) x 3/16" (4.7mm) flat steel.
1 - 1" (25mm) x 6" (15.25cm) cold-rolled steel rod for axle extensions.
16--1/4" (7mm) x 5/8" (16mm) bolts, nuts, lock washers
2 --3/8" (10mm) x 3/4 "(20mm) bolts, washers
2 -extra rear axle nuts which fit the bike to be adapted.

PROCEDURE 1. The stand assembly is divided into two parts: the rectangular base frame and two triangular upright supports. (See Figure 3). Measure and cut the five pieces of 3/4" (20mm) angle specified for the base frame. MITRE the corners at 45 degrees so they fit together tightly and form square corners.
[pic]

FIGURE 3 BASE ASSEMBLY

2. Weld the rectangle together. Do not weld the center frame member to the rectangle yet. 3. Measure and cut as specified the 5 pieces for each upright support. 4. Carefully assemble the upright support pieces for welding, being sure to leave a 1/8" (3.2mm) gap in the base of each support. (See Figure 3). This gap will mate with the center frame member of the base frame, allowing the upright supports to slide to accommodate different rear axle widths. Note that the two upright supports are not identical. They are mirror reflections of one another. Also note the orientation of the various pieces of angle, how they fit together etc. See drawings and photos of stand. (FIGURES 3 & 4) [pic]

FIGURE 4 UPRIGHT SUPPORT ASSEMBLY

5. Weld each upright support assembly together into a secure structure. 6. Place the upright supports onto the base frame, and position the center frame member so that it mates with the gap in the side supports. Mark its position, and weld it in place. OVERALL ASSEMBLY 1. First off you need to obtain a conventional washing machine, a bike, and a toolkit. Try to find either a broken washing machine and bike or ones that are no longer being used, following the “reduce, reuse, recycle” mantra! 2. Modify your washing machine: a. Remove the outer metal shell, usually white in color, from your washing machine by removing and unscrewing every bolt on the machine. b. Take out the electric motor from your washing machine frame. c. Remove the pulley from the motor’s shaft. d. Take off the drain hose that connects the tub to the pump. e. Save the belts from the pulley. 3. Modify the Trainer using your pulley a. Buy three tension pins from a hardware store and a drill bit. b. Drill three even spaced holes on the pulley. c. Have the pulley positioned on the fly wheel so that it is centered and drill through the flywheel. d. Hammer in the tension pins. 4. Piecing it all Together a. Position your bicycle stand and the washer in a position that you think will work for the design. b. Measure/Estimate how long of a belt you will need. c. Take the belt from step 1 to a hardware store and get one that’s the same except closer to the estimated size that you need, which will most likely be longer than the one you have. d. Drill and attach a large piece of plywood under your washer. e. Attach the belt with the training stand resting on the piece of plywood. f. Test your configuration. g. Drill holes to attach the training stand feet. h. Modify your configuration as necessary. 5. Try washing your clothes in your new nifty laundry machine!

...I. INTRODUCTION Pott’s disease is a presentation of extrapulmonary tuberculosis that affects the spine, a kind of tuberculous arthritis of the intervertebral joints. Scientifically, it is called tuberculous spondylitis. Pott’s disease is the most common site of bone infection in TB; hips and knees are also often affected. The lower thoracic and upper lumbar vertebrae are the areas of the spine most often affected. Pott's disease, which is also known as Pott’s caries, David's disease, and Pott's curvature, is a medical condition of the spine. Individuals suffering from Pott's disease typically experience back pain, night sweats, fever, weight loss, and anorexia. They may also develop a spinal mass, which results in tingling, numbness, or a general feeling of weakness in the leg muscles. Often, the pain associated with Pott's disease causes the sufferer to walk in an upright and stiff position. Pott’s disease is caused when the vertebrae become soft and collapse as the result of caries or osteitis. Typically, this is caused by mycobacterium tuberculosis. As a result, a person with Pott's disease often develops kyphosis, which results in a hunchback. This is often referred to as Pott’s curvature. In some cases, a person with Pott's disease may also develop paralysis, referred to as Pott’s paraplegia, when the spinal nerves become affected by the curvature. The disease progresses slowly. Signs and symptoms include: back pain, fever, night sweats, anorexia, weight loss, and...

...Introduction Dengue fever has become a common problem in the typical community. Its main cause being the clogged drains, unsanitary canals, and polluted surroundings. In these environments, the insect spreading dengue, Aedes aegypti, thrives. The researchers decided to focus on the root cause of the disease. The researchers would like to find an alternative, more economical method of exterminating them in their breeding places other than commercial insecticides. And in this pursuit to find a substitute, the researchers came across the guava fruit (psidium guajava), which had promising properties. (insert stuff about why we chose guava blahblah about properties….. use RRL for info.) The guava fruit was collected, osterized, soaked in ethyl alcohol, concentrated and evaporated to obtain a semi-solid extract. There were six blocks for replicates, five groups with 100mL water and different guava extract concentrations each – 3%, 5%, 8%, 12.5%, and 15% - and commercialized larvicide as positive control and one setup with dechlorinated water with 1mL ethanol. The commercial larvicide proved to be the most effective, but the guava extracts also have a positive effect on the larvae, though minimal. The study should be able to aid in the reduction of health problems brought about by Aedes aegypti. It may also help the community in controlling the mosquito population at an early stage by means of an eco-friendly larvicide. Not only will it be eco-friendly, it will also...

After having years in the work force without a degree, we know that if wewant to move up in our careers or obtain our dream job; a college degree is preferred. However, once we return to school, we're not in a student mentality anymore. Especially having a full-time job with, or without, having to support a family. For this reason, being academically successful comes with various steps that involve setting goals, learning styles, writing process, resources and having integrity. Setting goals can give you a long-term vision and short-term vision. In other words, an educational and career goal. It focuses on your acquirement of knowledge and helps you to organize your time and your resources so that you can make the very most of your life on how you planned it. As a result, the first step is to have an education goal. It’s always great to have an educational goal that will lead you to your career goal. For example, my educational goal is to obtain a bachelor's degree in Organizational Security and Management. The reason I set that as my educational goal is because my career goal is to become a peace officer (law enforcement officer) and then transition over to an air marshal when I obtain sufficient experience.

...Introduction       An organizational design specifies and describes the formal and the informal structures and processes within an organization through which the organization pursues its mission and objectives. An organizational design, thus, is the framework within which an organization functions. Both internal forces and external forces influence the character of an organization’s design. An organizational design tends to be defined in terms of structure, processes, and size (Chatain & Zemsky, 2007; Knoll, 2007; Zismer, 2011).       The findings of a description and an assessment of organizational design of a group practice family medicine clinic are presented in this paper. The description and assessment include the identification of the internal forces and the external forces that have influenced the nature of the organizational design of the clinic. The effects of these forces on organizational structure, organizational processes, and organizational size are addressed in the paper. Specific consideration is given in the discussion to the effects of accountability mandates on the organizational design of the clinic. The Internal Forces and the External Forces Affecting the Organizational Design of the Clinic       The external forces that act on the organization in this case, a group practice family medical clinic, exerted a greater effect on reshaping the organizational design of the practice than has been true of the internal forces that also drive changes in...

The aim of this study is to look at the effect of changes occurring in the global and/or regional economic environment on the multinational operations of “Unilever” during the period 2001-2006. The global and regional environment is passing through tremendous changes since the start of the year 2000. Globalisation, deregulation, financial liberalisation, economic reforms, advances in technology, enhanced activities of merger and acquisitions (M&As), launch of the euro as a single currency, changing corporate governance, etc amid financial crises such as recessions following the event of 9/11 etc all have affected the operations of Unilever. These all have led to more accommodating monetary and fiscal policies in the East Asian economies, lowering interest rates in USA and Europe, liquidity expansion, and fiscal and aid packages introduced by Japan which in turn have helped to improve these conditions (UNCTAD, 2006). What are the effects of these changes in the global and regional economic environment on inflation and interest rates? How has it affected the business operations, management structure, etc of Unilever? What kind of exchange rate exposures impacted Unilever and how has it managed these exposures while operating as a multinational corporation (MNC)?

...INTRODUCTION Whether you’re shopping for the holidays or for everyday items, you see a lot of price tags. While consumers probably don’t stop to consider the pennies on the price tags but a lot of businesses had been doing this practice called the ‘left digit effect’ on psychology of pricing. For example, in the market today, most goods are ending in Php 0.99 or in Php 99.00 regardless of its tenths or hundredths digit. This is supposed to suggest that the consumers are getting the best possible price or the item has been marked down. This doesn’t say that consumers are fooled, but although they can always round it off to the nearest tenths or hundredths, for some reason the consumers are compelled to buy thinking this could be a bargain even if they’re conscious of the said tactic. Though most businesses apply the left digit effect to engage more consumers to buy their products, some don’t utilize this strategy and the prices of the goods end in zeroes. In places like expensive restaurants or jewelry stores, products are often rounded off in the nearest hundreds or thousands because they portray to the consumers luxury and class. The message is clear that they are at the wrong place if they expect a change from the said store. We are surrounded by numbers every day and these numbers affect our mind. And every day we make decisions whether we are conscious of it or not. This research will explore what is called the ‘left digit effect’ and discover what influences people when...

...March 11, 2013 Introduction to Hypothesis Testing 1. Reminder: We have been finding probabilities related to given sample means based on given population means and standard deviations A. Example: what is the probability of finding a sample mean that is further from the population mean than this sample mean is? B. Why ask this question? - maybe this sample actually came from a population with a DIFFERENT mean - if so, we’d say the difference between our sample mean and population mean is “significant” – i.e., not due to random chance 2. Formalizing this logic… Statistical hypotheses A. The Null Hypothesis: H0 - states that there is NO difference between population means - this is like saying that any difference in sample means is due to chance - we always start by assuming this (like “innocent until proved guilty”) B. The Alternative Hypothesis: H1 - states that there IS a difference between population means - this is what we conclude when a difference is too unlikely to happen by chance C. How unlikely is TOO unlikely? - we set a cut-off point: the alpha level (α) - the alpha level marks the extreme parts of the distribution: the critical region - the critical region is usually the extreme 5% - if the sample mean is in the critical region, we reject the null hypothesis (guilty) - otherwise we accept the null hypothesis (not guilty) 3.

...Drug-Induced Osteoporosis: A Review of Medications That Affect Bone Mineral Density Drug-induced osteoporosis is common and may result in significant morbidity and mortality for patients. The World Health Organization (WHO) has defined osteoporosis as bone density less than 2.5 standard deviations (SD) of the mean gender-matched, young healthy population (T-score at or below -2.5). Osteopenia is defined as loss of bone with T-score between -1 and -2.5.1 Many drugs have the potential to decrease bone mineral density (BMD). TABLE 1 lists the agents discussed in this lesson. Most of the disease states that are treated with these drugs also predispose the patient to low BMD, so the medication may be adversely affecting an already compromised bone structure.2 The most significant consequence of low BMD is a fracture.3 [pic] Bones provide support for movement, protect vital organs, and are the largest repository for calcium and other minerals.3 Ninety percent of the body's calcium is in the skeleton.4 Bone is constantly being remodeled, with old bone being resorbed and new bone forming.4,5 The rate of annual calcium turnover is 100% in infants and 18% in adults. The cycle of bone resorption and consequent formation is approximately 100 days.4 Process of Bone Remodeling Bone remodeling is a complex, highly orchestrated process involving the balance of many factors. The cycle of bone remodeling occurs in stages, beginning with the formation of osteoclasts, bone resorption (by osteoclasts)...
