School considerations

20080407 23:36

When thining of going to college in EE, there are many options.  Dont make a mistake and go with the easy choice.  Surveys prove that most graduates end up working in the same area as their school.  So think about where you want to end up.

 Also, some schools have better financial aid programs.  Check out what your top schools have to offer.  It may be best to stay in the state of your current residence, as many schools have in-state tuition that is much less than out-of-state tuition.

 Another consideration is graduate school.  Many schools make it harder for you to enter their graduate school if you got your undergraduate degree from them.  the idea is that they want some diversity, so they make it easier for gradutes from other schools to get in to the gradute programs.  So you may want to think about 1) do you think you may want a graduate degree?  and 2) where would you want to get your graduate degree?  These days a gradute degree is a necessity for some of the better jobs.

Electrical circuits are systems with a closed circle, so the electricity can return throughout the loop. The system may have many pieces, but if it is not closed, it is not a circuit.Electric systems that have voltage, other pieces such as diodes or resistors can be analyzed by mathematical means to find transient, DC and AC response.A system that has active electronic pieces generally cannot be analyzed by the same mathematical techniques, but will need something more sophisticated in order to be created or understood.To create an electrical system, electrical engineers should calculate the voltages and other elements for various locations around the loop. Some mathematical techniques work well when the system has the same input and output specifications. Other systems will need more sophistication or perhaps can only be estimated.  Software is available to do this kind of analysis.

Q. How would you proceed to figure the road speed of
traction.
A. Would first determine the circumference of driver, then
ascertain how many revolutions the engine made to one of the
drivers. Multiply the number of revolutions the engine makes
per minute by 60, this will give the number of revolutions of
engine per hour. Divide this by the number of revolutions the
engine makes to the drivers once, and this will give you the
number of revolutions the drivers will make in one hour, and
multiplying this by the circumference of driver in feet, and it
will tell you how many feet your engine is traveling per hour,
and this divided by 5280, the number of feet in a mile, would
tell you just what speed your engine would make on the road.

The Acorn Brass Works of Chicago make a very unique and successful

little oiler which forces a small portion of oil in a spray into the
valve and cylinder, and repeats the operation at each stroke of the
engine, and is so arranged that it stops automatically as soon as the
oil is out of the reservoir; and at once calls the attention of the
engineer to the fact, and it can be regulated to throw any quantity of
oil desired

A cross head pump consists of a pump barrel, a plunger, one vertical

A cross head pump consists of a pump barrel, a plunger, one vertical
check valve and two horizontal check valves, a globe valve and one stop
cock, with more or less piping. We will now locate each of these parts
and will then note the part that each performs in the process of feeding
the boiler.

Now the glass gauge is put on for your convenience, as you can determine

the location of the water as correctly by this as if you are looking
directly into the boiler, provided, the glass gauge is in perfect order
Now the glass gauge is put on for your convenience, as you can determine
the location of the water as correctly by this as if you are looking
directly into the boiler, provided, the glass gauge is in perfect order.
But as there are a number of ways in which it may become disarranged or
unreliable, we want to impress on your mind that you, must not depend on
it entirely. We will give these causes further on. You are not only
provided with the glass gauge, but with the try-cocks. These cocks are
located so that the upper and lower cock is on or near the level with
the lower and upper end of the glass gauge. With another try-cock about
on a level with the center of glass gauge, or in other words, if the
water stands about the center of glass it will at the same time show at
the cock when tried. Now we will suppose that your glass gauge is in
perfect condition and the water shows two inches in the glass. You now
try the lower cock, and find plenty of water; you will then try the next
upper cock and get steam. Now as the lower cock is located below the
water line, shown by the glass, and the second cock above this line, you
not only see the water line by the glass, but you have a way of proving
it. Should the water be within two inches of the top of glass you again
have the line between two cocks and can also prove it. Now you can know
for a certainty, where the water stands in the boiler, and we repeat
when you know this, there is nothing to fear from this source, and as a
properly constructed boiler never explodes, except from low water or
high pressure, and as we have already cautioned you about your safety
valve, you have nothing to fear, provided you have made up your mind to
follow these instructions, and unless you can do this, let your job to
one who can. Well, you say you will do as we have directed, we will
then go back to the gauges. Don”t depend on your glass gauge alone, for
several reasons. One is, if you depend on the glass entirely, the
try-cocks become limed up and are useless, solely because they are
not used.

The engineer who don”t know how to throttle his engine never knows what

engineer who has a thorough knowledge of the throttle and uses it,

The engineer who don”t know how to throttle his engine never knows what
it will do, and therefore has but little confidence in it; while the
engineer who has a thorough knowledge of the throttle and uses it,
always has power to spare and has perfect confidence in his engine. He
knows exactly what he can do and what he cannot do.

Q. Does boiler plate become stronger or weaker as it
becomes heated?
A. It becomes tougher or stronger as it is heated, till it
reaches a temperature Of 550 degrees when it rapidly
decreases its power of resistance as it is heated beyond this
temperature.

Too many engineers forget that when he is fooling around that he is the
only one losing time. The facts are the entire crew are doing nothing,
besides the outfit is making no money unless running.
