1) This spring hub arrangement dampens torsional vibrations from the engine.

2) It also absorbs shock loads imposed on the drive line by sudden or violent clutch engagement.

So what does an aerospace engineer wear? You can just look on Google Images and see what they're wearing. Some of them look like they're wearing casual clothes (who'd want to wear a tux to inspect aircraft?), like a t-shirt and jeans, etc. Some pictures even look like they have lab coats. But that's just a rough view of what they'd wear. I've even read on some websites that they have to wear uniforms, but that depends on your company.

he is the greastest person ever cuse he a fix my stuff

That is a matter of opinion.

The ballast is a transformer that steps the voltage up higher than its incoming voltage.

This is usually used with flourescent, metal halide, & sodium vapor lights.

The higher voltage is needed to 'excite' the gases within the bulbs and make the molecules bounce around and give off light.

In cfbc boiler fuel system like a very important funtion of in all process.

fuel feeding have two types one is over beding system and other one is under bed system.In over bed system coal is carried by conveyer belt from bunker to spreader that's time coal size approx 6-10 mm crushed.spreader distribute coal on the surface of bed uniformly.This type of fuel feeding system accept over size of fuel also.In compared with under feeding system this is more reliable.Now these days have some boiler have both feeding system.In under bed feeding coal size crushed approx 1-6 mm which is throw from conveyer to combustion panel.

A microprogram is a program that is consisted of micro code, which is the lowest level language possible on a computer. Microcode is even more low level than machine code and acts a platform for machine code to run on top of, directing the physical operations of the processor by itself.

The for parts of the computer system are

1,hardware

2,software

3,data

4,users

The ATX power supply and AT power supply had different connections for the computer motherboard. Also the ATX power supply had provision for some parts of the power supply to be switched on-and-off by the electronics on the motherboard, possibly under the control of software. With an AT power supply it necessary for the user to physically operate a switch. This control feature means that a computer that has an ATX power supply can provide, for example, a "wake-on-LAN" or "wake-on-modem" feature whereby the computer will switch itself on if their a signal on the ethernet cable or modem cable. If necessary it should be possible to adapt an ATX power supply to replace an AT power supply. This could be done by finding an adapter cable. The mother board cable from the ATX power supply would then plug into the adapter cable and the adapter cable would plug into the motherboard.

A Service Engineer's duties depend on the industry they work in. For example, in Aircraft manufacturing, a Service Engineer provides technical support to the business unit operations such gas turbine engine/airframe/accessory overhaul and repair. He would also provide technical support to ensure cost, quality and output levels meet desired targets. Other duties would include investigating and resolving issues of product engineering, testing, and quality. They are essentially manufacturing engineers. But this is just one example - service engineers in computer programing for example would do something completely different.

That is a broad question but I would have to say some of the most important subjects would be digital audio & theory, a recording class of some sort, depending on which software you, the school or the business uses. Music theory, media arts, and of course math because, audio technology, or sound engineering, media production, music production which are all basically similar degrees are a science.

Yes. Mass Comm is only about writing. Anyone can learn to write. Study something that interest you. Example: If one wants to become a PR in Apple, I bet would rather hire a computer science student or programmer that can write well.

Writing is a learning process that can be learn in parallel and part-timely.

Not a lot. A fire fighting pump found on most fire engines is the centrifugal type. Other than the amount of water it may flow and the number of discharges it can supply, there is no difference (although I'm not sure what "ordinary centrifugal pump" refers to unless it is a trash or sump pump). Centrifugal type pumps weren't always used in the fire service, but they are the standard now because they can spin (they can pump or maintain pressure) even when there is no water actually flowing.

1.Graphical Representations makes it easy to understand and interpret data at a glance.

2.Graphical representation can be understood by layman easily.

3.A picture speaks a thousand words as the old saying goes. I can change that to a graph interprets a thousand calculations. In other words it tells you all that you need to know without the clutter of too much detail.

4. nobody could make an item to the exact requirements, not only are they required for manufacture, maintenance workers need to view them

5.Verbal instructions are not feasible, they can easily be forgotten or misunderstood. .

6. An Engineering drawing shows everthing required for manufacture (sizes, shape, material, accuracy required, number required, surface finish to name just a few)

7.Drawing is the oldest and efficient way to put data in simpler terms. remember even caveman used it to convey message by drawings. but engineering drawing is to compose data with precision in simpler form.engineering is all about planning and implementing and no planning s perfect without a schematic.

The main reason of selecting a lower frequency for up-link channel in GSM is because of free space path loss. The more is the frequency the more is the loss.

As mobile phones, being a battery driven device, have limitation in terms of power we should always look for lower path loss. Whereas BTS antennas can transmit the signal (in down-link channel) with a comparatively high power, which will compensate the path loss.

And that is why it is chosen to have lower frequency for up-link and higher frequency for down-link in GSM standards. The same theory applies in almost all type of radio communication.

NOTE: Frequency and power are independent of each other. For example you can control the transmission power of BTS antenna, which still transmits in the same frequency.

ATA is much faster.

Materials engineers are involved in the development, processing, and testing of the materials used to create a range of products, from computer chips and aircraft wings to golf clubs and snow skis. They work with metals, ceramics, plastics, semiconductors, and composites to create new materials that meet certain mechanical, electrical, and chemical requirements. They also are involved in selecting materials for new applications. Materials engineers have developed the ability to create and then study materials at an atomic level, using advanced processes to replicate the characteristics of materials and their components with computers. Most materials engineers specialize in a particular material. For example, metallurgical engineers specialize in metals such as steel, and ceramic engineers develop ceramic materials and the processes for making them into useful products such as glassware or fiber optic communication lines.

FOR n-type semiconductor the majority charge carrier is electron and for n-type semiconductor it is hole.

the majority and minority charge carrier is result of free electron and hole.

the majority charge carrier is responsible for transport of electron.
