Mechanical Engineering

Description
Mechanical engineering is a discipline in engineering which applies the principles of physics, math, engineering and materials sciences to analyze, design,manufacture and maintain mechanical systems. Engineers who study in this field are very creative and masters in math. Mechanical engineers must have an understanding of subjects like thermo/fluid dynamics,mechanics,kinematics,electricity,biology, chemistry and much more. They use these principles along with tools, such as computers (CAD), and industrial machinery to develop things like aircraft, skyscrapers,weapons,robots etc. This field over laps with many other fields like business, civil engineering, electrical engineering, aerospace engineering, chemical engineering etc. They are very versatile people. They do many things like consulting, planning and managing projects big and small also organizing reports and design plans, solving problems ranging from medicine to economic issues.
How They Build Things (The Process)
Some of the education/training they receive (also some experience they get)
Some of the education/training they receive are the typical subjects they would take relating to the profession, like calculus, trigonometry, thermo dynamics,fluid dynamics, physics, material sciences etc. They even learn things not related to the profession like social sciences or humanities. They also do practical stuff like lab sections and also designing/computer courses, where they get assignments like design projects etc. Some student also go for co op or internships, to get to know what the job is like and they are going to expect. Aspiring mechanical engineers go for undergraduate studies or a bachelors degree in the beginning learning basic engineering principles and principles from other fields like civil engineering. The bachelors degree usually includes the things listed above and also some specialized courses (relating to engineering and specific fields) later on. It would take 4 years to complete a bachelors degree. Some engineers may also go for graduate studies, and do further research and hone their skills in specific areas of the profession. At some Point engineers even go for a professional license, to go up the ranks and get better positions, and jobs.
Early stages of career/career itself
Mechanical engineers start off getting supervised by experienced engineers for a while, until they have a good idea of what they are to do. After that they can start working on their own, like manage their own projects, or do consulting etc. They live a pretty successful life, they get good pay, lots of work, and lots of job options. They are very busy people, as they not only do tasks such as designing and building devices, but also advise financial managers on things like sales etc. They meet with many different people of all professions to get the requirements they need, and then go on the computer to design devices. They manufacture many things along with other people, and manage all sorts of projects. Their education is a good foundation for other fields, like business, so some mechanical engineers go on to studying in the field of business and getting jobs in management etc. They always learn new things and gain more experience and this opens up to many new projects and opportunities. They may take graduate studies to get certain positions or even get licensed as it lets them do more than they already can. They have lots of career options so they eventually find what is best for them.
Examples of some fields in Mechanical engineering
Aerospace/automotive: Which is basically where mechanical engineers design and build engines, and other components for aircraft, marine, and space vehicles and also make the safety features in the vehicles (along with crew and passenger accommodations.) . They even develop the equipment used to build the aircraft, marine, and space vehicles (also maintain them)

Advanced energy systems:The mechanical engineers who specialize in this field, develop new energy systems (which are alternatives to thermal energy, fuel cells, gas turbines etc.), and also find innovative ways to use existing sources or energy like tidal or coal.

Bioengineering:This field focuses on systems, processes, and equipments used in biotech, and pharmaceutical (medical) industries, for example the structure of cells etc. Engineers in this field deal with artificial organs, medical devices, biomechanics etc. Mechanical engineers use their knowledge to design and make biomechanical devices or systems.
Job Description (Purpose)
Mechanical engineers are responsible for using their knowledge of motion and energy (basically subject knowledge of math,mechanics, design, physics etc) for designing, building, installing, and maintaining all kinds of machinery, tools, and components
Some Of The Duties Involved
- Designing and building power plants,machines, components, tools, and equipment
-Overseeing the installation of equipment and machinery and also the prduction team, technicians etc, and gives them advise
-Analyzing dynamics and vibrations of mechanical systems/structures
-Investigating mechanical failures or unexpected maintenance problems
-Using computer software like CAD for designing and modeling plans
-Confirm system/product capabilities by designing testing methods, or testing its properties.
-Maintains products and company reputation by following government regulations

Skills/ Qualifications
Skills/qualifications would include, requirement analysis, design skills, presenting technical info, equipment maintenance, conceptual skills, quality focus, general consulting skills, control engineering, production planning, technical zeal, job knowledge, problem solving, communication skills, organization, planning and management, team player etc.


Education/Training Requirements
Most employers usually get people who have a bachelors degree, because a bachelors degree gives the engineer all the basic skills (like critical thinking), and concepts to start making products. Getting a masters degree is a bonus, because it will give people more options, and higher ranking positions like faculty or research positions. Things like getting a degree from and accredited program (CAEB) is also a plus and what some employers look for. Having skills like critical judgement, teamwork, computer, communication, and problem solving skills are in high demand. Finally, being licensed are job requirements for some organizations, it shows them you are dedicated to the job, and that you are a professional in your field, it opens up many positions as well. Being up to date in the latest technology is also important and people may hire people with this sort of knowledge. The main thing is to have experience and good education, and if people have this then the more money they are able to earn and the more positions that are available.
Training Availability
Mechanical engineers have lots of training available to them. They can get the education and training they need from engineering programs found in universities like MIT, or Waterloo, and take math,and science courses and also engineering courses teaching them principles of things like dynamics, motion, mechanics, calculus and algebra etc. They can also go for apprentice ships or some vocational programs, or go to technical institutions. They also have the option of doing things like co op to get practical experience. People can continue their education and training by doing graduate studies. They can attend work shops, and even use company training programs.
Working conditions
- Mechanical engineers will usually work regular business hours, but may have to work evenings, or weekends to finish work
- They work in workshops, factories, offices (doing CAD design, or consulting), building site/production area (construction site)
- They will have to work around lots of machinery, heights, and in dirty or noisy conditions. So wearing safety equipment may be required like hard hats, goggles, overalls etc
- They may have to travel between different sites locally or travel overseas to supervise projects (power plants in Germany, or oil rig in the ocean etc.)
-Will have to work in teams and meet different people (financial managers, other engineers, and people who relate to the project etc.) for the purpose of designing and building something (ex: when building a mechanical heart, they would consult with doctors, surgeons, biomedical engineers.)

Potential Earnings
Mechanical engineers just starting out can get an annual salary of $41 311- 75 337. In their mid career (when they have more experience, and some more education) they can earn $51 654-98 342. Finally when they have lots of experience (say they finish graduate studies, get a PE license etc.), they can earn up to $58 474-119 668. The average they make is $43 522- 91 885. A typical full time salary for them would between $65 000-75 000. In Toronto their average wage (as of 2010) is $32.35/hour. The wages range from $20-50 per hour depending on the province or area.
Prospects Of Employment
Prospects are good. I mean every company needs mechanical engineers. There are many fields that mechanical engineers can choose from like transportation or manufacturing (aerospace engineering etc.) Mechanical engineers can even get jobs in management.Their education is a good foundation for many other fields as diverse as medicine, or law. It may also depend on the industry they want to go into and also the state of the economy. As long as they have all the skills and qualifications like teamwork skills, or good judgement etc, which are in high demand, many employers will look to hire them. Experience can boost job prospects as well. The more education they have, the more positions and jobs will be available to them. Employers always look for skilled workers.
Impact On Society
Mechanical engineers build useful products for society, and make peoples lives easier, by building things like cars, or ventilation systems etc. They make the buildings and houses we live in the tools doctors use and much more. Without them life would be much more difficult. They even build the machinery that helps them manufacture these goods. They make life easier and more efficient.
Impact On Economy
Mechanical engineers manufacture a lot of important goods such as computers or phones or cars etc. These goods are in high demand, and when these goods are sold the people selling them make good money, that's why countries like the US are very rich, because of all the products they produce. The more goods that are sold, the more the economy grows. Not only that By producing these goods, people are required to do certain tasks such as assembling components, packaging, and transporting goods. Jobs are created as mechanical engineers make these goods or even structures, and to complete these tasks. The more people working the more taxes that are payed, which all help an economy grow. We have to pay maintenance fees and all sorts of stuff for living in a house, and this money goes to the development of the economy. Mechanical engineers also pay taxes as well, and consume the products that they make to. They help many industries like transportation, by making their vehicles, and people pay to ride these vehicles like buses or trains and so on...

Intro
First, mechanical engineers would work in the office, where they meet specialists from other fields like bankers, or financial managers, or even other engineers, to get all the requirements needed. Once all the requirements are gathered, they start designing with help of software like CAD, to design the machine or device, and once that is done, they build a prototype in a lab with many useful equipment and tools. Once the prototype functions properly, it becomes manufactured into the real thing, in a manufacturing plant by a seperate team of engineers. Once that is done, the manufactured component is taken to the field where it is installed. The mechanical engineer oversees the installation process, then does some tests to see if it is functioning properly, and then finds ways to improve the device.
This is Tachu Naito
This is Tokyo tower
He was an architect and engineer. He was born and raised in Japan. He helped build tall buildings in Japan, and even proved that they can withstand the most disastrous earthquakes and tremors. He made many amazing buildings and structures in Japan that can withstand earthquakes, and this was important since Japan receives quite a few earthquakes. Not only that he even built the infamous Tokyo tower, which is now a very important icon to Japan. He specialized in earthquake engineering and basically changed the engineering world with his work. When he finished one of his first projects (a theatre in Tokyo and a 30 m tall head office of the industrial bank of Japan), a few months later Japan was hit by a 7.9 magnitude earthquake, which severely damaged Tokyo and its surroundings. Hundreds of thousands of buildings were destroyed (700 000) or partially destroyed, but all of Naito's buildings were still standing tall, not affected by the earthquake at all. He shared his work with places like California, where frequent earthquakes occur. He changed how we build our structures, and because of him, buildings and other structures are much safer.
This is Henry Ford
Henry Ford was basically the father of industry. He shaped the way industry is today. He not only made some of the earliest automobiles, but also created ways to mass produce, using things like an assembly line (different groups of people do different tasks, and then one finished product is assembled) and a conveyer belt. Because of these ideas, making cars and other products became really easy. He made many different cars, like some which were fuel efficient, or some which were light weight etc. He even mass produced, things like bomber planes for world war 2. He also made an industrial plant for his ideal of mass production. Many people in the U.S bought his cars, since they were affordable, and also easy enough to maintain by themselves. He even built his own engine in his kitchen, and then eventually made his first car called the Quadricycle . He shaped industry, which helped in producing many other useful goods.
Mechanical engineering is one of the oldest and broadest engineering disciplines. It dates back to thousands of years ago. There were many engineers who aided in the development of this field, like Archimedes, or Henry Ford. Many past inventions are bing innovated by mechanical engineers. In this presentation, I will briefly explain each topic, and the topics may include job description, the education they receive, training requirements etc, some of the things about their profession basically.
Conclusion
So that's about it for this presentation, there are lot of things to know about mechanical engineers. They have very good careers, they get good salaries, have lots of options for jobs like business administration etc. They have lots of training available, and learn a lot throughout their careers, they can get jobs easily as long as they have lots of experience, and the necessary skills. They live very successful careers, and impact both society and the economy. They know many things like thermodynamics, mechanics and much more.

I chose this field because of my love for deigning and creating things. This field has almost everything I like, for example, the math and science they use to make things. Math and science are 2 of my favorite subjects. They have lots of creativity and imagination, leading them to build tall skyscrapers, hight tech phones and tablets etc. I like their curious nature. I really admire how they try to change the world with all their inventions and creations. Some day I want to be able to do what they do now.
This is an example of some things they build. They designed and built the components for this ship like its engine, and thought of things like how much weight it can hold etc.
