How important is a mechanical engineering freshman's summer job to future employers?
Q. I just finished my first year of mechanical engineering at college. There's a paid graphic arts internship that I'm interested in and can easily get. Getting a mechanical engineering-related internship or job would be much harder because I live in NYC and things are competitive. How much should I worry about getting engineering-related experience in my first summer?

A. I am a 51-year-old mechanical engineer who had to hire, on different occasions, two experienced mechanical engineers and one right-out-of-school mechanical engineer. So I have some but not a heck of a lot of experience hiring. My two cents: Don't sweat it, take the graphic arts internship . You are too early in your studies to worry about getting an engineering summer job THIS summer. Do worry about getting an engineering summer job NEXT summer. My reasoning: 1.-No offense, but if I remember freshman year right (it's been a while) you probably haven't had the serious engineering courses that would allow you to have a serious engineering summer job freshman summer anyway. Basically, you can take the graphic arts job, be happy, not do… [cont.]

What does mechanical and thermal energy have to do with Global Warming?
Q. I am doing a project about the conversion that take place in Global Warming. I need to figure how heat, mechanical energy, and thermal energy is converted.
Asked by Amelia S - Tue Jun 3 21:09:01 2008 - - 1 Answers - 0 Comments

A. Global warming is the theory that the earth is warming. There is little accurate data to support this, but historically we are very cold, almost as cold as the ice ages. So, likely we are warming. Anthropomorphic global warming is theory that man's activities contribute significantly or mostly to global warming. No evidence for that, but many people fervently believe in it anyway. Not clear what energy conversion you are talking about. Energy can have different forms. Two basic catagories are potential energy and kinetic energy. Potential energy is stored energy that can do work; kinetic energy is energy stored in the motion of an object. Classical examples are kid on a swing or roller coaster. As the kid or coaster reaches the top, speed… [cont.]

Though you have to make sure which sector you go into. My advice is certainly dont bother with manufacturing and production engineering.

What is it like being a mechanical engineer compared to what you learn in university?
Q. I've always been interested in engineering (actually I've been interested in most science-related things). I recently saw this video of a mechanical engineering project where you had to build a very simple design that could sort out heavy ping pong balls from light ping pong balls, and that problem-solving aspect really persuaded me. How much problem solving do you actually do as a mechanical engineer? Can someone assure me that it's not all about fixing up faulty machinery (or is this where all the money is made?)

A. How much problem solving do you actually do? A lot. Sometimes I've done 100 hours a week, for several weeks at a stretch. Going to bed thinking about a problem and waking up next morning still thinking about it. I once spent about 10 years, on and off, figuring out why something consistently didn't work properly for a few of the customers who used it, while the majority had not problems at all. (And after 10 years to find the solution, the modification to fixing it took about half an hour to make). "Fixing up faulty machinery" is mostly about solving problems, not attacking it with hand tools, and there are usually technicians around who are much better qualified to do the hand-tool work than you would be after a university engineering… [cont.]

What is the mechanical power required to keep the house cool?
Q. An air conditioner is used to keep the interior of a house at a temperature of 21 C while the outside temperature is 31 C. If heat leaks into the house at the rate of 9 kW, and the air conditioner has the efficiency of a Carnot engine, what is the mechanical power required to keep the house cool? I thought I was supposed to use Carnot's engine equation Tc/Th = Qc/Qh but that's not working. What equation does this involve?
Asked by mburrows13 - Sun Jul 18 19:13:35 2010 - - 1 Answers - 0 Comments

A. thermal efficiency of air conditioner is measured in COP (coefficient of performance) COP (cooling) = carnot = [Tc] / [Th - Tc] = Qc/Win Qc = rate of heat energy (power) to be thrown out = what that leaks in from outside = 9000 W Win = mechanical power required to do the job (expenditure) Win = [Th - Tc] Qc / Tc = [304 - 294] * 9000/294 Win = 306.12 watt

A. If you are interested and want to learn, you are halfway to successfully completing a mechanical engineering degree course. To achieve your aim, you also need to master calculus as it is very important in mechanical engineering. To be sure that you know what is involved in studying and working in mechanical engineering, do a Google search for "mechanical engineering courses in the USA" and read the website entries for some of the colleges and universities that teach the program. You ought to also read the entry in Wikipedia.

What is the total mechanical energy of a spring?
Q. Here's the initial question: 1.A 12.67kg mass is laying on a frictionless surface and it is connected horizontally to a spring (k=500N/m). The mass is set into simple harmonic motion (moving horizontally) with amplitude of 10cm. What is the period of oscillation? What is the frequency of oscillation give answers in both Hertz and radians/second. (1 Hz = 1 cycle per second.)? What is the total mechanical energy? What is the maximum velocity of the mass? What is the maximum acceleration of the mass? I have everything but the ME figured. T = 9.87sec f = 0.10Hz / 0.638 rad/sec vmax = 0.628 amax = 3.944 I am having trouble grasping the concept of total mechanical energy.

Asked by ellyvstheworld - Tue Apr 10 23:37:05 2007 - - 1 Answers - 0 Comments

A. Mechanical energy describes the potential energy and kinetic energy present in the components of a mechanical system. So in this case, the question is asking you about what is the potential energ and kinetic energy of the spring. ME = PE + KE But it just so happens that when the mass has ZERO velocity, the system's PE is at a maximum, and KE =0 (since KE = mv and v =0). So ME = PE(max) + KE(min) = kx + 0 = (500)(0.1) = 2.5 J Also, we can calculate the ME when v = v(max), which is when x = 0, so ME = PE(min) + KE(max) = 0 + mv = (12.67)(0.628) = 2.5 J So you see that the ME of the system is always the same.

If you really want to get tricky you can use gear-reduction to redirect the fan (you know, so it's not straight out from the side of the wheel) and, also, to increase the speed of the blades. You, of course would want to put a hamster (or some other small rodent) in the wheel. Or you could just blow on it. Or leave it outside tonight (I'm assuming the water is in a bowl).

How do the mechanical parts of a die cast lock get inside?
Q. I understand the manufacturing process for a laminated lock, but cannot figure out how the mechanical workings end up in a die cast lock and still work. Clearly the parts are too large to fit in through the hole made by inserting the key plug, and the parts would be unable to move if they were cast in. So how do the mechanical workings still operate inside the die cast body? I understand the basic concepts of using cores to make gaps in a die cast, but how would that work for say, a brass die cast lock?
