Mechanical Engineering Interview Questions And Answers

Express your details like this.
I did it in 4 years for undergraduate (summers included) and 2 more for Masters Degree, part time.

Engineering Circuit Analysis. I don't do well with that stuff.

I worked on a ground coupled heat pump project that I really liked. Very interesting stuff, and environmentally worth it.

Presently, I work for an Engineering company designing a solar-sourced power plant. I am building a computer model of it. Pretty neat, huh?

Besides the computer model, I have been working on some pump selection/purchases, and some system designs.

I would say that there is, because the economy is up and companies are spending more money.

There must be about 20 or so? Not sure.

Not sure I understand your question. I need skills in Thermodynamics, and computer modeling, as well as some heat transfer and fluid dynamics. I am pretty broad skilled.

Depending on where in the country you work, I earn around $80,000 permanent employment, or $100,000 contract.

absolutely Yes to both.

Depending on the company, Yes. Being an engineer is a good choice. If it is money you want, be a MD. That pays more.

Finishing my Masters degree. I did it later in life, and shouldn't have waited. Advanced math was difficult for me, as was, as I said, anything electrical. (Now I work for electric utilities in power plants. ... Go Figure! lol

Usually 8 hour days, but lately I have been working 10 hour days.

I attended the University of _________. A small school, Good education, low cost. Not any scenery to distract you either.

Good question. I decided to become a Mechanical Engineer during my first semester. It just seemed to fit the things I enjoyed.

I wrote some subroutines that are used in a popular software today. Lots of fun, but it didn't pay much.

I hope this one. The solar-sourced power plant.
Its up to you to show what is your the most important and helpful project...

In order to make wise investments in a marketplace experiencing increasing levels of risk, companies are turning to feasibility studies to determine if they should offer new products, services or undertake a new business endeavor. The purpose of a feasibility study is to determine if a business opportunity is possible, practical, and viable. When faced with a business opportunity, many optimistic people tend to focus on just the positive aspects.

A feasibility study enables a realistic view at both the positive and negative aspects of the opportunity. A feasibility study is an important tool for making the right decisions. A wrong decision often leads to business failure. For example, only 50% of start-ups are still in business after 18 months and only 20% are in business after 5 years.

Yes, provided there is an oxygen source. A spaceship with liquid hydrogen and liquid oxygen will blow up quite well in the vacuum of space. Chemical explosives will also explode in space since they function by breaking weakly bonded chemical components; no oxygen is necessary. Nuclear explosions can of course occur in space, too. The United States military in the 60's performed a series of nuke tests in outer space, and found out what EMP can do, when they briefly wiped out Hawaii's electrical grid for a few hours.

* a) Sulfur is used in tire construction
* b) Aluminum and iron in the car body and engine
* c) Quartz is used in windshield construction
* d) Chromium is used for chrome plating
* e) Copper is used in wiring
* f) Magnesium may be used in the wheels
* g) Zinc would be used in rust plating
* h) Gold may be used in the spark plugs and in electrical connections
* i) Tin may be used in solder
* j) Lead will be used in the batteries
* k) Tungsten may be used in the light bulb filaments

The type of refrigerant used and sometimes the amount of charge determines the proper suction pressure of any air conditioning or refrigeration system.

Motion detectors work to help with construction work.

The SR-71 was made mostly out of Titanium (very high strength to weight ratio) and it got off the ground fine. In addition, a two-seat airplane cost $33 million in 1960s dollars, so no one would ever be able to afford an airliner made out of it.

In general, it seems simple: polishing scored cylinders and pistons, replacing worn seals, replacing excessively worn or damaged parts, etc. However, for an ordinary person, the problem I have run into is finding a readily accessible source of parts, as the hydraulic repair industry seems to be a closed fraternity.

Yes. Lying on its side, it will break with very little pressure. That is why, when you break an egg, you always strike the side.
