Engineering

There is a good scope of safety engineering. It helps in prevention and management of risk associated with health and safety. Safety engineering practices are required in various fields of life. Each field of research will require specialized procedures and techniques for assurance of safety.

vehicle body networking is just a way to use less wire through-out the vehicle e.g instead of running a wire from the rear light to earth on the battery you just earth the rear light to the vehicles chassis.

It should be marked, either on the diode or on the box it came in. If you can't find the mark, then you have to measure it yourself. Take the zener diode, a battery or DC power supply, and a resistor. Wire them all in series, with the NEG (cathode) end of the diode closer to the POSitive side of the battery or power supply. Connect your voltmeter across the diode, and slowlyincrease the power supply output voltage while watching the meter. You'll see the voltage across the diode increase slowly, tracking the power supply, until you reach the Zener voltage. At that point, the voltage across the diode won't increase any more; it'll just stay there at its 'reverse breakdown' voltage, which is the Zener voltage. (If the voltage across the diode goes to around a volt and won't go any higher, the polarity is wrong. Reverse either the diode or else the power supply.) You probably want a wild guess at what the value of the resistor should be. That's difficult to specify if I don't know the power rating of the Zener diode you're testing. I'm going to make the following suggestion completely in the blind: Select the resistor to limit the series current to 30 mA even if you have to crank the power supply up to 50 volts. R = 50/.03 = 1.5 to 2 K-ohms, rated for a couple of watts.

Business computing is done at work; personal computing is done at home.

The points in leaving certificate acceptable will depend widely on the choice of college. However, the general expectancy is 385 for Corporate Law and 440 for Civil Law.

It turned out to be very easy))) But I was thinking for a while to solve the problem... )))
Ok. Lets say we have inputs S3..S0. Let S3 and S2 go to inputs of each of FOUR of decoders; and S1 with S0 go to the inputs of the FIFTH decoder. The four outputs of the FIFTH decoder go to enable lines of the four decoders. Voila! It might be confusing, but just draw the whole thing and you'll see. Now you just need to enable the fifth decoder... HA-HA!

The United States is the only major industrialized country in the world that does not use the Celsius scale. It still uses Fahrenheit because it would be too complex a project, very expensive, and also very dangerous to change over.

Absolutely! Technical Graphics Communication can be considered a language in the sense that you are able to communicate ideas to other individuals who understand the subtext.

For example an American Civil Engineer can hand a French Civil Engineer a print and both of them would understand the ideas implemented in the drawing even though there is a language barrier.

The same can be considered of mathematics and programming languages.

The amount of money can you save by turning off lights is directly determinant on how many lights you have running, at what power rating and for what amount of time. For instance if you have one light bulb with a 75 watt rating running for 100 hours that will be 75kW-hours (where kW is equal to W x 10^3 or W x 1000) kilo-watt hours are a typical measurement in household meter boxes. If your electricity is being supplied at $0.08/kw-h then it is simply 75 x 0.08 which is equal to $6.00. therefore you can see that, with numerous lights, turning them off can offer a substantial saving over a long period of time, not to mention an important environmental benefit.

Friction can cause kinetic energy to change into thermal energy

The dissadvantage of the current NASA Shuttle program is that it is outdated. Some of the shuttles still use 8track tapes, so it is cheaper to retire them and bring in a new system instead of update them.

It depends on work history, level of experience and ability to impress your boss with a great attitude. Entry level building Engineer (or maintenance mechanic) could be as low as $8-$9 per hr. But with experience in a wide variety of trades where you know how to save the company money by doing all the repair work yourself (eliminating a need to use outside contractors) and having a good attitude about it, you could make over $70,000 a yr if you're promoted to manager. No one will promote a complainer. Prove you're valuable and the money will come. I've heard of Directors of Engineering at very large hotels that make over $100,000. But for that you'll have to have some schooling, be very well spoken and have the ability to play management politics. Bottom line is you can only get out of it what you put into it.

Pressure guage is first to come to mind.

It depends on the equation and the coefficient. Coefficients can be constant (Boltzmann constant, Avogadro's number) but they can also be variable (Reynolds number). The coefficient of gravity, g, is 9.81 m/s^2 in metric units on Earth.

The fastest aircraft publicly known is the SR-71 "Blackbird", which set speed records at 1905.81 knots (2,193.17 mph, 3,529.56 km/h)

There may be faster aircraft today; the rumored "Aurora" aircraft using a pulse-jet engine may be capable of Mach 5 or more.

The Space Shuttle reaches speeds of up to 17,000 MPH while in orbit, and reaches mach 20 during its return to Earth and landing.
