ENGNEERNG AND NATURE



What is Engineering?

Engineering is the practical application of science and mathto solve problems, and it is everywhere in the world aroundyou. From the start to the end of each day, engineeringtechnologies improve the ways that we communicate, work,travel, stay healthy, and entertain ourselves.

Engineers are problem-solvers who want to make things

work more efficiently and quickly and less expensively.From computer chips and satellites to medical devices andrenewable energy technologies, engineering makes our modern life possible.



What is Mechanical Engineering ?

Mechanical engineering is a discipline of

engineering that applies the principles of physicsand materials science for analysis, design,manufacturing, and maintenance of mechanicalsystems. It is the branch of engineering thatinvolves the production and usage of heat andmechanical power for the design, production, andoperation of machines and tools.It is one of theoldest and broadest engineering disciplines.



Engineering emerged as a field during the industrial industrial revolutionrevolution in Europe in the 18th century; however, itsdevelopment can be traced back several thousand yearsaround the world. Mechanical engineering scienceemerged in the 19th century as a result of developmentsin the field of physics. The field has continually evolvedto incorporate advancements in technology, andmechanical engineers today are pursuing developmentsin such fields as composites, mechatronics, andnanotechnology. Mechanical engineering overlaps withaerospace engineering, building services engineering,civil engineering, electrical engineering, petroleumengineering, and chemical engineering to varyingamounts.



Relation of nature and engineering became more importantafter industrial revolution.Because thereafter engineeringvalue increased an unpredictable manner. in the directionof Human expectations and needs, engineers was

expected to meet them.

Engineers have to use nature, but this use makesirreversible harm to nature day by day .n, engineering and

nature loop, if we continue like that nature will be sufficientto meet the needs.



What s Nature ?

Nature is constantly self-renewing and changing,covers all

of the assets of living and inanimate matter. Human factors are not enabled.

Elements of matter and energy is

considered to occur.



Scientists discover the nature such as pressure directlyprop to temperature, they think hard to find the laws of nature. On another hand Engineers uses these laws of nature to invent to equipments such refrigerator, engine.

And also engineers uses scientists laws to triumph in their inventions. Engineers are concerned with costs andscientists are not.

As seen,in engineering,we use ; knowledge of nature

resource of nature



RESOURCES OF N ATURE



Natur al resources exist in natural form in which are usuallyfound within environments where there are no disturbance byHumans.These resources areimportant in our life. It mayexist as an individual such

as air, fresh water, or as aliving organism such as a fish.Natural resources arecategorized as either renewableor non-renewable resources.

It may be divided into twocategories from which itwas originated, either ina biotic or abiotic form.



Renewable resources are ones that can be replenishednaturally.

Non-renewable resources are resources that formextremely slowly and those that do not naturally form inthe environment.

1. Engineers to realize the desired or intellectual projectsrequire energy sources.Engineers attend using the

proper use of energy or renewable energy way.



Why Engineers Have To Use GreenEnergy?

The first positive environmental impact of renewable energysources, fossil from the damage caused by energyproduction and use will be stopped.

The damage will not be enough to stop a moment, in theuse of fossil fuels during that time the damage so far fromthe fossil fuels needed to be fixed will need to userenewable energy sources instead.

For this reason, today, in addition to conventional energysources, new and renewable known as an energy source,solar, wind, geothermal, hydrogen, sea-wave energiesand biomass energy sources, such as studies andresearch conducted on and applications are performed.





CLEANER ENERGY BETTER LFE

Non-renewable sources will expire some day and wehave to us our endangered resources to create more

non-renewable sources of energy. The speed at which such resources are being utilized

can have serious environmental changes. Non-renewable sources release toxic gases in the air

when burnt which are the major cause for global

warming. Since these sources are going to expire soon, prices of

these sources are soaring day by day.



Solar energy makes use of the sun¶s energy. It isadvantageous because the systems can fit into existingbuildings and it does not affect land use. But since the areaof the collectors is large, more materials are required. Solar radiation is also controlled by geography. And it is limited to

daytime hours and non-cloudy days.Wind energy uses the power of the wind to produceelectricity. Although it is the largest job producer, it is relianton strong winds. Wind turbines are large and, although youcan use the area under them for farming, many consider

them unattractive looking. They are also very noisy tooperate. In addition, they threaten the wild bird population.



Hydroelectric energy uses water to produce power. This isthe most reliable of all the renewable energy sources. Onthe down side, it affects ecology and causes downstreamproblems. The decay of vegetation along the riverbed cancause the buildup of methane. Methane is a contributinggas to greenhouse effect. Dams can also alter the natural

river flow and affect wildlife. Colder, oxygen poor water canbe released into the river, killing fish. And the release of water from the dam can cause flooding.

Geothermal energy uses steam from the Earth¶s ground togenerate power. It uses smaller land areas than other

power plants. They can run 24 hours per day, every day of the year. Disadvantages are that it is very site specific and,along with the heat from the Earth, it can also bring up toxicchemicals when obtaining the steam. Drilling geothermalreservoirs and finding them can be an expensive task.



Biomass electricity is produced through the energies fromwood, agricultural and municipal waste. It helps save onlandfill waste but transportation can be expensive andecological diversity of land may be affected. In addition, its

process needs to be made simpler.Ocean energy is a clean and abundant energy form. Itdoes, however, have high costs. Ocean thermal energyalso requires close to a forty degree Fahrenheit differencein water temperature year round. In addition, construction

and laying pipes can cause damage to the ecosystem.



Solar Power





specific engineering disciplines has been developed for theefficient use of energy and the environment ;

Environmental engineering

Energy engineering

Planetary engineering

f we know what have to do with nature,energy

resources,we can create more green and unharmfullproduct.This green types makes people more healty.
