What is the basic function of a megger?
On the whole megger testing is non destructive. What happens is a DC voltage is applied to the device or winding under test. It is an insulation test to see is the insulation has been injured in any way to cause a short circuit when normal power is applied to it. On my megger there are 3 ranges 300V, 750V, and 1000 volts. Applying the proper voltage is essential to not damaging the device you are testing. Working voltages up to 240 volts should use the 300 range. Working voltages up to 600 volts use the 750 volt range and working voltages above 600 use the 1000 volt range. As you can see if you used the 1000 volt range on a device that had a working voltage of say 24 volts you could damage the insulation just by testing it. So meggering a device is non destructive if you use the tester as its instructions tell you to.

For the sort of standard text-book stuff being asked in this question it's much better to use the excellent Answers.com and other well-known "reference" or "encyclopedia" sites. You will also see very useful photos and diagrams to help to explain the answer.
The actual answers on WikiAnswers must currently be text-only and, for other information such as pictures, photographs, etc., separate links must be added below the answer.
For instance, the Related Link to Answers.com's site - shown below the Related Questions for this answer - shows a circuit diagram, as well as a good description, of a "megger" instrument.
WikiAnswers is not ideal for use as a "reference site" or an "encyclopedia site" because you have to wait until someone either writes a special answer to your new question or merges it into an existing question asking about the same thing.

Vernier Caliper are made with different materials even plastic vernier calipers are also available in market however generally stainless steel is used in making of vernier calipers
Generating 5136 alarm fanuc control cnc?
ALARM 5136 (FSSB: NUMBER OF AMPS IS SMALL)
The number of servo amplifiers recognized by the FSSB is insufficient,
compared with the number of controlled axes.
Most of the time the problem is an optical cable. When an optical cable is unplugged from the socket, there should be a red light coming out of one of the optical cables AND a red light coming out of the opposite side of the socket.
FSSB setting screen
If this alarm is issued, display the amplifier setting screen from the FSSB
setting screen. Only the servo amplifiers recognized on the FSSB are
displayed.
Optical cable or servo amplifier
The optical cable that connects together the last recognized amplifier and
the next one may be defective.
Or, either of the amplifiers connected together with that optical cable may
be defective. Check the power supplies of the amplifiers.
Power fault of a servo amplifier
This alarm may be issued if a power fault occurs in a servo amplifier. A
power fault occurs if the amplifier control power supply voltage drops,
if the +5 V conductor of the pulse coder cable is ground, or for other
reasons.
Axis control cards
The axis control cards installed on the CNC may be defective.
See Section 8.14 for explanations about the mounting location of the axis
control card.
What is the use of the tail stock sleeve in centre lathe machine?
Tails tock sleeves are used on CNC lathes. It is the equivalent to a tail stock quill on a center lathe but in this case it uses hydraulic pressure to move it in and out of the tail stock.
The function of both tail stock sleeve or quill is to clamp the workpiece by means of a center that is inserted into the sleeve or quill. On a center lathe it is used for drilling also but not on a CNC lathe.

How can you make your vernier callipers more sensitive or more accurate?
the instrument can be made more sensitive by making vernier constant less ie by incresing the no of division on vernier scale or by decreasing the value of main scale.

Area equal pi * r^2. Diameter of six equals radius of three. So according to Google, 9 * pi * (15*12) = 5089 cubic inches.
Now, again according to Google, 35 (ft^3) = 60 480 in^3 per hour. I'm going to leave you to figure out the answer from here!
Bethlehem Steel what year did the blast furnaces at johnstown pa shut down?
E furnace (made ferro manganese) and L furnace were shut down the night of July 20, 1977 due to the Johnstown Flood that caused the plant to lose power and water damage which caused the blowing turbines to shut down.
H furnace was saved due to it being relined in 1976 and was idle when when the flood struck. H was restarted and operated until Aug 1981 when it was abandoned when Johnstown was changed to electric steelmaking furnaces.
H furnace was never fully tapped out. It was torn down and the iron that was left in the hearth is still visible. It was said that iron recovery was attempted, but it
was unsuccessful so it was left as a sort of monument.

How long is the twine inside an official major league baseball?
According to the Roanoke College C&E News Summary of March 29, 1999:
"Who has ever seriously considered what goes in to making baseballs? To Rawlings, this knowledge is excrutiatingly important. Today, instructiouns call for a cork nucleus that weighs exactly 0.5 oz and is 2.86 to 2.94 inches in diameter. It is to be incased in two thin rubber layers - one black, one red - and weigh a total of 7/8 oz. This nucleus is then machine-wound under high, consistent tension with 121 yards of four-ply blue-gray wool, 45 yards of three-ply white wool yarn, 53 more yards of three-ply blue-gray wool yarn and 150 yards of fine white polyester-cotton blend yarn. THis is coated with rubber cement before the cover is put on. The cover consistes of two pieces of elongated figure-eight-shaped white cowhide, dampened to permit strething, which is then handstiched together with 216 raised stitches, using 88 inches of red cotton thread. Finally, the ball is rolled for 15 seconds while still slightly damp so the seams are even and reasonable flat.
At this point, the balls are still not ready for the big league. Balls are selected at random from each shipment and shot from an air cannon at 85 feet per second at a wall made of northern white ash (the wood used to make bats). Each tested ball must bounce back at between 0.514 and 0.578 of its original speed to be suitably lively for Major League Baseball."
What two factors are used to determine the size of a lathe?
The two factors that determine the size of a lathe are the "swing" and "distance between centers". The swing of a lathe is the length measured from the center of the hollow spindle or chuck to the nearest part of the bed multiplied by two. Distance between centers is the distance measured between the chuck and tail stock.
It's "ultrasonic weld," rather than "sound weld." Sounds more "engineering-ish," anyway.
This is done by clamping two objects together - usually plastic ones, but thin metal can also be ultrasonically welded - and directing a high-power beam of ultrasonic energy at the mating point. The beam causes heat, which makes the two materials in the joint melt. When they cool down, they're fused together.
How do you get a skipping rope on Nintendogs ds?
You buy it at the discount store on walks. Try to visit both on one walk and sooner or later a skipping rope will show up and you can buy it! Hope I helped :)
Jump rope is not just a childrens' playgroung game. It ISa sport. There are even jump rope teams that do lots of cool, fun stuff. Somethimes they even perform for people around their state, the country, or even the world! Expert jump ropers can do really sick, awesome tricks too! Im on a jump rope team called FLEUR DE FEET from Louisiana. Yeah we're pretty awesome!
