What do breadboards do?

In the kin of electronics, breadboards are used for experimental testing of circuits. Once a circuit is laid out on the board, components can be easily added or taken out of the circuit. No soldering is required on the board as there are specialized clips that hold the components firmly. Once the circuit is tested and works the way it was designed to a PC board is designed to take the components

What are the guided transmission media?

Guided transmission media means the data signals are guided along the path like cabling system.They dont have any other go they have to pass through the given cable or wire.

Guided media are of 4 types :

1. Open wire eg:- Electrical wires from poles.

2. Twisted Pair.

3. Coaxial Cable.

4. Optical Fiber.

What do you use vector images for?

If you're printing something really big and you don't want the file size to be huge, vector is the only way. Example: I wrapped a 20-foot bass boat for a Famous Bass Angler in January. By the time we went around the transom and curved the vinyl in to match the bow, the sheet was probably 26 feet long. The wrap was really graphically intense--lots of curves, flames, sponsor logos--and only needed about 175MB of disk to hold both sides. To you, that might be huge, but come to my shop and I can pull out 600MB files all day long. 175MB is tiny to me.

What are the duty and responsibility of engine cadet?

How long does a patent last?

It depends on a number of factors including: #what type of patent (design, utility, plant, etc), #when it was filed (its earliest priority date), #when it was issued, #where it was issued (which country), #whether it remains valid (if it ever was), #if there is a terminal disclaimer in the file, #whether the owner has paid periodic maintenance fees, #and if there are special adjustments to the patent term for the technology (such as for certain delays caused by federal approvals). For example, a utility patent filed in the USA in 1994 and issued in 1999 would have a statutory term of 17 years from date of issue (later than 20 years from date of filing, which was prior to 1995), but will expire on its 4th (or 8th or 12th) anniversary if the necessary maintenance fees and late charges are not filed, and may be invalidated earlier (in whole or in part) by various judicial findings, or may be extended by USPTO adjustments to compensate for delays in FDA approvals. International treaties have also attempted to have utility patents for the same invention expire simultaneously in most countries, based upon 20 years from the date of filing.

I have a 1998 Sable that has had the same problem. Every time it has been caused by a leak in a vacume tube. It has been replaced 3 times now on my car.

How can a plane not be detected on radar?

The impedance of plane material is made equal to the impedance of air,in this way the waves sent by radar does not reflect by material of plane and pass through plane and do not come back to radar.That is why,plane remain invisible to radar.This material was invented by a PHD proffesor in UET Lahore Pakistan.

Does commencement of construction include engineering design?

Has to. If the engineering is not done, you should not be be able to start building.

No. Engineering is a term of design; not construction. To construct means to excavate and build. While engineering may be a prerequisite for construction it is not to be included within the same phase as physically constructing of something

Why does air escaping from the open end of small pipe make a lot more noise than air escaping at the same volume rate from a large piece?

Sound waves are produced from disturbances in the pressure of an environment ( which is why in space, no one can hear you scream...theres nothing to be disturbed by your scream). So, if the same volume, and therefore the same mass, of air is escaping from a smaller opening, the pressure disturbance is magnified since the pressure the air exerts on the atmosphere around it is greater.

How did engineering and technological advances lead to the end of the Middle Ages?

The "lost knowledge" in ancient Greek texts reintroducedby the Islamic Moorish invaders in Spain enabled the Europeans to build things that had not existed there since the fall of the Roman Empire. This ignited an interest in learning that had been largely extinguished under the Catholic church, bringing on the Renaissance and ending the Middle Ages. There were no actual "advances", only the reintroduction of previously existing knowledge either once lost or actively suppressed (e.g. the burning of the Library of Alexandria by the decree of the Coptic Christian Pope Theophilus of Alexandria in 391 AD).

What is weapons system engineering?

A weapons system engineer is a person who designs weapons systems or builds weapons systems. A weapons system may refer to a trigger assembly of a gun or a gun alltogether. For example the M4 is a weapon system. These engineers have designed barrel replacements, upper and lower register replacements and other modifications to make the gun better. Look at the AR-15. A bunch of weapons engineers made that together. Then on top of that made different modifications to give you the M4, M16, and other rifles. A weapons system engineer may have modified the M4 to give you the M4-A1, and so on.

What is an interface control document used for in systems and software engineering?

An application programming interface is a form of ICD for a software system, in that it describes how to access the functions and services provided by a system via an interface. If a system producer wants others to be able to use the system, an ICD (or equivalent) is a worthwhile investment.

What is the purpose of valves?

A valve is a device that manipulates the flow of a fluid (liquid or gas) from one area to another. It can simply shut off the flow, it can increase or decrease the amount of flow, or it can reroute the flow of a fluid to a different pathway, as well as many other functions.

What is a post indicator valve?

A valve that is installed in the main fire line serving a building to turn the water off that is flowing into a building in the event of a fire within a building. Most commonly found in the yard near the building and sometimes wall mounted on the building. The building is intended to shut the water off in the event of a fire and the building is not safe to enter to shut the water off at the sprinkler riser.
