Engineering is about math applications

Math is the most important element of engineering. There’s no way we can build a machine without math help. Being an engineer means being someone who is good in math. With correct calculation, the machine can be operated in ideal situation. And then, what is happening when math is not the element of engineering ? It will be no engineering science. We would still using conventional ways in life which are less effective. We need math more than we know.

Internet has a problem solver for this. An online math help is the latest invention which is competent to nowadays technology. It’s a simple mechanism for us actually. Online math tutor will help us with methods those effective in engineering. Online math tutoring is as easy as communicating with other people in the internet and it has more advantages than we study math’s books by ourselves. We need all part of our body to learn math,including our mouth to talk in math.

There are lots of free online math help those worth to try some.  Free online math tutoring is way to find which online math help has the best method, and it’s a nice move, because it’s free. Now it’s your choice to start develop your engineering with good math.

engineering mathematics – daily usage

From stress analysis of machine components (using finite element packages), to numerical descriptions of the artist-drawn shapes of new gadgets (using CAD packages), to the use of numbers associated with the mundane jobs of production, inspection, and statistical quality assurance(using statistical packages), to the economically critical planning problem of what material to buy in what amount from where (using optimization packages), and so on, applied mathematics is everywhere in the everyday world of software applications in routine engineering.

From calculations of heat and mass flow in steam power plants and car radiators, to calculations of air flow in cooling fans, to calculations of molten metal flowing and mixing in weld pools, applied mathematics turns the wheels of engineering analysis and design.From reliability in electrical power system grids to traffic in networks (both tar roads and optical fibres), mathematics crosses boundaries in a way no other technical subject can.

The applications mentioned above are the subjects of many books. Yet, they collectively fail to convey the excitement that engineering applications of mathematics can have. There is more to the story than a list of applications. some ways those more interesting are online tutoring. With Online math tutoring you’ll get math answers by submitting your math problems. some Precalculus help that we got from online tutoring is very useful. you can also get something like statistics help or even chemistry help. this is a fun and good way to learn engineering mathematics.

Electromagnetic frequency

Given the long use of radio waves, there have in fact been numerous studies investigating the possible health effects of radio frequency (RF) fields in the past 50 years. The health risk due to heating has been known for more than a century; therefore most research conducted in the last several decades has been on possible effects that are not related to heating, so-called non-thermal effects. From the extensive corpus of research, the only established health effects have been related to the well-known heating effects of radio waves. Several hundred studies using mobile phone signals specifically are listed in the research database on the World Health Organization’s (WHO) website. The great majority of these studies has not indicated any adverse health effects linked to mobile telephony. Several expert groups and health authorities have reviewed all the available research and the WHO, for example, summarizes the current status as follows: “None of the recent reviews have concluded that exposure to RF fields from mobile phones or their base stations causes any adverse health consequence.”. WHO and several other health authorities and expert groups have clearly stated that is no adverse health effects can be attributed to mobile telephony. However, a consistent message has also been that some additional research would be helpful to increase the knowledge and to ensure the best possible assessment of health risks.

EMF (Electromagnetic frequency) is very useful. It is worth with future education for our next generations. Our kids need helps and we can start build our world sustainable and educations must be our first priority. We can start it by go to http://www.tutorvista.com. There are facilities for our kids such as Free Algebra Help that is very useful. Math help is needed most nowadays such like algebra help and we can’t just ignore it. Other facilities those we can get are solution for math problems, about fractions, algebra even homework help. It’s a good start to get a better future.

Broad field

Indeed, a degree in electrical engineering can open many doors, in part because electrical engineering is so broad. Electrical engineers have taken on many tasks that you might expect people with other technical degrees to do. Semiconductor processing, for example, is highly populated by electrical engineers, but its basis is in physics and chemistry. Other areas include optics (as applied to communications), aerospace engineering, and even life sciences. “A lot of people don’t realize that a lot of biomedical devices are actually electrical devices,” noted Georgia Tech’s May.

Engineering jobs also cut across technical disciplines. More and more, mechanical, chemical, and biomedical engineers use electronics to measure a product’s performance. “Who says you’re not going to do test and measurement on a chemical process for drug manufacturing?” asked Looft. “That’s a huge area. And you better know a little bit about chemical processing when you go into that job.”

Some people with engineering degrees move out of engineering jobs but stay in their respective industries by moving into sales, marketing, and management (a few even become editors covering the industries from which they came). Others move into fields such as law and medicine. Law firms, looking for patent lawyers with technical backgrounds, may hire engineers or engineering graduates and pay for law school.

Those who choose to enter the engineering work force may find that they need skills beyond math, science, engineering basics, and problem solving. We asked the participants what additional skills employers now look for in engineering graduates. While we received some differing answers, everyone agreed that communications skills sit atop the list.

No longer is it enough to design circuits and get test results. You must communicate those results through written reports and presentations. Georgia Tech’s Williams noted that the university has integrated writing of technical documents into several courses, which UCSB’s Long echoed. WPI has even created an interdisciplinary major or double major in technical writing.

While schools have responded to employers looking for better communications skills, some in academia remain skeptical. One such person is Professor John Orr of WPI. “The standard example is if you hear an after dinner speech from the VP of company xyz, [he or she] will describe that employers need graduates with good communications skills, good teamwork skills, and some global experience. But when hiring managers come to campus, they look for skills such as experience with the latest Cadence software release. They’re looking for engineers who can be productive from day one.”

Regardless of whether communication courses are included, it’s becoming virtually impossible for schools to provide all of the required engineering skills at the undergraduate level. In fact, some people have begun to question if you should be able to enter the engineering work force with just a bachelor’s degree. Employers are looking more and more for graduates with master’s degrees, and the number of master’s degrees relative to bachelor’s degrees has risen in the past 30 years (Figure 1). (continued)

At the same time, the number of PhDs has remained relatively flat. During the last business downturn, companies may have scaled back their research budgets, relying on universities to do the work. “There’s a lot less research going on in industry than there used to be,” said UCSB’s Long. “Most companies have decimated their research labs.” Long argued that companies are looking for fewer PhDs than they did 10 or 15 years ago because they don’t have the facilities and don’t want to pay the higher salaries.

In recent years, industry has become more involved with academia. That’s good for the most part, as long as industry lets the teachers teach. Often, companies sponsor student projects or contribute to the funding of research labs. Students benefit from having worked on real-world projects and by making industry contacts, which can lead to employment upon graduation. Employers benefit because they can hire graduates with practical experience.

Overall, industry involvement in projects is welcome, because the companies provide equipment, materials, and sometimes funds for student projects. “If they’re paying for a project, then they should have the say over the project,” said WPI’s Looft. “But it can get too involved. I have companies that want to tell us what we’re going to do, educationally.”

Drexel’s Kam doesn’t agree. “I’m sure that there are horror stories here and there of companies who donated the equipment and wanted to control the curriculum,” he said. “But I wouldn’t call it a trend nor would I say this is widespread.” Georgia Tech’s May agreed that a few companies want too much involvement, but he doesn’t think it’s excessive. Companies are, after all, stakeholders in the graduates that these universities produce.

Looft said that companies go over the line when they say “you didn’t get it done” meaning that a student project didn’t produce a marketable product. When that occurs, he reminds companies that a student project is an educational endeavor that may not produce a working product.

Kam takes a different approach. He argued that companies need to get more involved in the educational process. “Industry is absent from the accreditation process,” he said. He wants to see greater participation from industry so universities can produce the engineers best qualified to keep companies competitive.

Whether you think the world has too many or too few electrical engineers, you’ll probably agree that engineers make an impact on people’s lives every day. Engineering has proven to be a satisfying career for many. Your work makes a difference in the world. Now, go out and tell someone how engineers contribute to society. I am sure many engineers proud to wear lanyards around their neck about their company.

Math and science: just the beginning

Many students consider engineering careers because they’re good at math and science and receive encouragement to enter the field from their parents, teachers, and guidance counselors. “I think that’s a reasonable thing to do,” said Professor Gary S. May, ECE department chair at Georgia Institute of Technology (Georgia Tech). “It doesn’t mean that it’s the only career that’s available to you, or you’d be a perfect engineer because of that. But I think it’s a reasonable thing to tell students that engineering is an option for you because you have this aptitude.”

An aptitude for math and science is certainly a requirement for an engineering career, but is it enough? Not according to Professor Richard Vaz of Worcester Polytechnic Institute (WPI). Vaz, who is associate dean of the Interdisciplinary and Global Studies Division at WPI, said that the best engineers also have a passion for solving problems.

UCSB Professor Steve Long also cited “the willingness to do critical thinking” that makes good engineers. He argued that engineers are naturally curious and they want to know about something that’s not necessarily in a textbook.

Not everyone, though, has a clear reason for studying engineering. “When I ask students why they want to study engineering, very rarely can they articulate a reason,” said Vaz. “If they can, it usually doesn’t line up well with what engineers really do, which is solve problems and make the world a better place.” Some people, we learned, go into engineering because of the prospect of earning a decent living with just a bachelor’s degree. “That [belief] won’t get you very far,” added Long. He also cited “pushy parents” as another wrong reason that some young people study engineering.

While some people study engineering who might have been better at something else, many people who could make good engineers miss the opportunity because they don’t know what engineers do. “We don’t see enough of the brightest people coming into engineering because early in their educational paths, they get advice that essentially blocks their way,” said Moshe Kam, professor of ECE at Drexel University and VP of the IEEE Educational Activities Board (EAB). “There is a feeling that we won’t have enough people, we won’t have the right people, and because of that, we won’t have enough innovation,” he added.

Kam based his conclusions on meetings with representatives from 53 companies that hire electrical engineers. He also found that high school guidance counselors may unconsciously steer women with the ability and prerequisites for studying engineering into other fields because, “It’s not something that women do, and that’s a myth that we need to shatter.”

Georgia Tech’s May noted that some of the issues that divert women away from engineering also apply to minorities. “We have to show that engineers are normal people with normal lives with the same sorts of concerns as everyone,” he said. “This also affects our ability to recruit minority students. I say that from experience.”

Lucrative College Degrees

Math majors don’t always get much respect on college campuses, but fat post-grad wallets should be enough to give them a boost.

The top 15 highest-earning college degrees all have one thing in common — math skills. That’s according to a recent survey from the National Association of Colleges and Employers, which tracks college graduates’ job offers.

“Math is at the crux of who gets paid,” said Ed Koc, director of research at NACE. “If you have those skills, you are an extremely valuable asset. We don’t generate enough people like that in this country.”

This year Rochester Institute of Technology hosted recruiters from defense-industry firms like Lockheed Martin and Northrop Grumman, as well as other big companies like Microsoft and Johnson & Johnson.

“The tech fields are what’s driving salaries and offers, and the top students are faring quite well,” said Emanuel Contomanolis, who runs RIT’s career center.

Specifically, engineering diplomas account for 12 of the 15 the top-paying majors. NACE collects its data by surveying 200 college career centers.

Energy is the key. Petroleum engineering was by far highest-paying degree, with an average starting offer of $83,121, thanks to that resource’s growing scarcity. Graduates with these degrees generally find work locating oil and gas reservoirs, or in developing ways to bring those resources to the Earth’s surface.
