I presume you are talking about how to change the direction of rotaion on an electric motor. To change the direction of a three phase motor, switch any two wires of the three phase feed, and the motor will rotate in the opposite direction.

I am a Recording Manager/Engineer for a record company and the best way to explain the answer for this question is to divide it into two examples. If you are lucky enough to be exclusive to a record company and be on salary, then you will be making at least 200K a year. The other way for Engineers is to get a cut of the studio profit from each job. Studio's have set prices for services. Say they charge for one track- 500 for production, 200/hr. for recording, and 1000 for mastering, then the studio made 2100 (3 hrs. for recording). The studio, the producer, and the engineer get a cut. If you got an equal one third of that then for that day you made 700. At five days a week, 52 weeks a year, you make 182000 for that year. The variables are all different and to become a engineer you need to be very talented (being a musician helps a lot) and have gone to school for engineering, 99/100 times. I got lucky knowing someone who started a record company. Remember- the producer and engineer are extremely vital parts to the record making process.

This is nonsense. There is no way, and I mean ZERO that a recording engineer makes that much money. I assume this was written by someone working for those "Learn Recording Engineering" Colleges. Here's the truth.

If you are VERY LUCKY, you might be making up to $14 or $15 an hour. Most engineers work for much less (like $5 an hour) and a significant percentage work for free.

Most recording engineers are unemployed. There are no jobs in this profession, and I"ll bet you there isn't ONE job for a recording engineer in all of North America that pays more than $20,000 a year.

Most of the studios that make the albums you listen to have gone broke. Big studios now charge less than $900 for a WHOLE DAY, so figure out the math. How much, after paying the costs, are they going to pay the engineer?. Right! Nothing or next to nothing.

Do not ever consider 'recording engineering' as a career. You will be unemployed, or working for $5 a hour, if you are lucky enough to make that much.

The last post is correct. There are no jobs for recording engineers anymore, so I'd say the normal income for a recording engineer is zero. I feel angered by the false promises coming from the hundreds of 'recording institutes' that promise the world and take tens of thousands in . . umm . .. let's call them 'tuition fees'. These places spit out thousands of so called 'recording engineers' every year, the only problem being there are no jobs out there. They say you are 'placed' if you are working as a salesman at Future Shop.

I have to agree with RealityCheck's answer. If you are considering going into recording engineering as a career - don't. There is nothing out there for a recording engineer, except perhaps recording lousy high school bands in some kid's Mom's garage.

Before you can nail down a salary range for "recording engineer", you must pinpoint the environment of the job. All of the answers thus far are biased, as they all seem to focus only on coporate music industry recording. For example, if a production manager or DJ at a radio station creates a PSA, they've recorded, at the very least, voice-over. If a sound-designer creates a specific sound for Theatre, traffic for example, it's field-recorded. A videographer creating a corporate training video: room, scene and situation audio recording... All of these are examples of recording engineering. To whomever stated that "Big" studios are charging $900 per day - where did you get your information? The last producer I engineered for in a "Big" studio commanded $850 per hour. To the person who is angered over "tuition fees". Umm..how many BA degrees, or psych degrees, or "Liberal Arts" degrees do these institutions "spit out" every year? Should all those people be mad, too? There are plenty of jobs (and money) in recording engineering - you don't have to work in a recording studio to work as a recording engineer. Remember, sitting around in a bedroom mixing loops in Reason or running band sound in a bar on the weekends doesn't make you a qualified engineer, and usually those are the types complaining about no career opportunities. If A-list corporate studio recording is what you're after, then be prepared when the ellusive door opens - do your homework, network, be reliable, hone your skills, and build a reputation through your adaptability, knowledge, and flexibility. As long as there is such a thing as multi-media, QUALIFIED engineers are in demand and very well paid. Personal example - my first "professional" lead engineer studio gig paid me enough to buy a flat in Manhatten. That doesn't happen at $5 an hour...

Your buddy who is making $800 a month as a 'recording engineer' is at the top of his profession. That's what kind of money you make as a recording engineer today at the very top of the pay scale. And he's one of the very few lucky ones that get paid, most have to pay to work or work for free. BTW - the chances of your buddy (the 17 year old child) making $100K as a recording engineer are zero. He's either going to be living with his parents forever, or getting an education and a real job.

I got a job 30 years ago as a recording engineer apprentice. I made 5 dollars an hour. I played in a rock band growing up, so the business interested me. As of today, I own my own studio, I do primarily work in the advertising industry, doing award winning work, and I make from 160,000 to 250,000 a year. While I got a job without a degree, this is much less likely to happen today. There are just too many degreed individuals out there now. My youngest employee earns 35,000 dollars a year, with full medical coverage, and 25% of his salary put into his retirement, totally funded by the company. And he has a degree, and he was competing for the job with 3 dozen other degreed individuals. While this may sound unbelievable to some of the respondents on this thread, I've checked with some of my contemporaries, and the best studios pay in a similar manner. Now, getting a recording degree will NOT guarantee you a job. You need to have a desirable attitude, and a positive, (not arrogant) posture, to succeed at the interview stage. Make no mistake, most people who get recording engineer degrees will never get a job in the business. But that isn't that much different from the rest of the degree programs coming out of college. I've read that only 30% of people with degrees are doing jobs in the fields of their degrees. That includes me. So, here's reality. If you know someone in the business, you have a leg up. That's true in any field. But if you want to be a recording engineer, you have to know two things. One, you won't make much money at first. Second, you may very well have to sacrifice a lot, to succeed. Most of those who have succeeded, have sacrificed much. Hope this helped. If you want an easy road to riches, this is not the field. If you are incredibly talented, you'll probably kick ass. On a side note, if you are so cool that you can produce a hit album out of your basement, you'll get rich. Degree or not. But that ain't easy either.

Weldolet and Sockolet are basically self reinforced fittings. Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service. Sockolet is used for socket welding branch connection, which require reinforcing pad.

They are both pretty hard to chew, and have little nutritional value. But seriously, it depends on what the application is. Aluminum is lighter. Stainless has other advantages. Each material corrodes in ways the other does not.

You don't provide enough information to answer that question specifically but I can give you a few probabilities. The possible range of a helicopter varies greatly with engine size, body size, weather and location. In general commercial helicopters can do from two to four hours in the air with a top speed of from 50 to 200 knots (air speed). This gives you an average range of around 200 miles...but like I said, there are many variables and these numbers can change greatlly.

I am referring to the puma helicopter in particular!

1,200 miles or 1,900km for an Apache Attack chopper.

The thermal conductivity of steel varies depending on the alloy. (It also varies as the temperature of the metal.) Stainless steels are generally only about a third as thermally conductive as carbon steel. Copper is about ten times as thermally conductive as carbon steel. If a "number" is somehow required for the thermal conductivity (k) of steel, try k = 40 W/m K (at about 25 oC).

Attend a college having a major in engineering (electrical, mechanical, computer, civil, etc.). In the senior year, most colleges have hiring personnel from many companies come to your campus for employment interviews. In my time, I received 3 job offers from these interviews. Very simple.

Instead of pushing straight down, the load of an arch bridge is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end.

The equivalent material is SAE 1045.

A rotary valve, at the ones I'm familiar with, is typically used to move solid materials from a hopper. Basically the valve is designed with a paddle wheel which is shaft-mounted and driven by a motor. The rotary valve is similar to a revolving door: the paddles or blades form an airtight seal with the housing; the motor slowly moves the blades to allow the solids to discharge from the hopper. I know how trumpet rotary valves work. Just tilt the trumpet sideways so the rotary valves face upwards and play.

It is very hard because it is the strongest.

Well before pneumatic tires were invented, tires made of wood or iron were fitted to stone, wooden or metal wheels to make them last longer. If you don't have a separate tire, the whole wheel has to be replaced when its outside edges get chipped and worn away. So it is probable that tires were invented soon after wheels because the people who invented wheels soon found out it was a good idea to have tires on them which could be replaced when they wore out.
