Q:what is a symbolic machinery?

It is an item used in a story to represent a more abstract idea. example- in Star Wars the dark side is represented by Darth Vader among others. The light is represented by Yoda and the Jedi. In this case it symbolizes the fight between good and evil. Another example is the Nazi flag. The Nazis revered it. To the rest of the world it is a representation of evil and darkness.

Q:This is a sentence from a novel which I do not understand its meaning. What is a whirling machine? and does it relate to scratching eyebrow? Or it is just an idiom? The setting of the story is around 1940.

The teacher(?) is implying that the children are stupid. That a machine (the brain) has to labour just to tell them to scratch their eyebrows!

Q:I don't know which to do. What advances better? Also i would plan on trying to get into OCS before im 34 and be an officer in one of these jobs, which one?

Winechan has zero experience or understanding of how the Coast Guard works - or the military in general. Speaking PURELY of numbers, there are many more MK's in the Coast Guard than there are SK's - so by the NUMBERS, more MK's will be advanced each year than SK's. The PERCENTAGE of people being advanced remain pretty close to the same for all ratings in the Coast Guard, so there really isn't a difference in advancement rates. Don't forget that to go to OCS, you will have to either have a four-year college degree, which is hard to get in the Coast Guard within your first couple of enlistments - OR - you'll have to be at least an E-5, with five years of Time in Service (and be on your second enlistment or later), with at least two years of college. Neither of these programs (regular OCS applications or TEMP commission OCS applications) are forgiving about age and age-related waivers, so make sure you can get the college and be able to apply at LEAST three or more times before you stand any realistic chance of being accepted. I've known folks that applied five and more times (the record I saw was EIGHT times!!) before being accepted to OCS. There is about a 10% chance of being accepted each time you apply... so it isn't easy. The FS officer (Finance and Supply) field is very small - a LOT of the officer-type functions are done by Warrant Officers. Engineering Officers (EO's) are more numerous, but they don't turn wrenches or actually work on machinery. Look at it this way: which field interests you more? Would you rather sit in a warehouse and count beans or be in oily bilges, turning wrenches? Some people LOVE one or the other, and rarely love the idea of BOTH career fields. Brian Raini

Q:Hi so I was just curious if I could get a good strength training workout without the machines like where you push with your legs or the machine where you pull the bar down and it pulls the weights up, I want to know if I can get a good daily workout with just my dumbbells and my bench, Detailed answers are greatly appreciated, any links to websites maybe? In advance I greatly appreciate helpful answers, thank you!

Yes. I always prefer free weights to machines. That's not to say machines can be of benefit though... The machine where you 'pull down' isn't necessary. As an alternative, you could just do weighted chin-ups. The leg press machine is also replaceable with squats, lunges, etc. Machine exercises can be useful, but you can get by without them. *I'd highly recommend investing in a weight rack. It'll help with squats, shoulder presses, and other things.

Q:Should the Bible be used when driving or operating heavy machinery?

As a heavy equipment operator who meditates on scripture, I don't see a problem.... ; )

Q:Why is hydraulic machinery so effective???

The simple reason is that Hydraulics utilizes fluid as opposed to Pneumatics (air) although both are referred to as fluid power , the liquid normally oil used in hydraulics is simply uncompressible. SO THE FLUID is essentially stronger than STEEL when a pump pushes the oil to a device like a cylinder, imagine the fluid being a solid BAR of STEEL say 6 inches in diameter, it is literally like pushing a bar of steel. Heavy equipment say could normally operate at say 2500 PSI out of the pump, since the pump pressure is essetially regulated, it is simply a matter of selecting the desired force and sizing say the cylinder (for instance) appropriatey. Since: Force = Pressure (pump pressure) times Area (of the cylinder) The forces are absolutely staggering with a quarter of a million pounds force off a 10 cylinder at 2500 psi pump output. the chart below may not have been converted properly, but if you work the equations, you will see that the incompressibility of the fluid is the secret to limitless amounts of power. Usually safety is the only limiting concern with hydraulics as it is easy to die working close to anything with such reserve and speed. Cylinder bore Force at 2500 psi 2 7,850 lbs 3 17,663 lbs 4 31,400 lbs 5 49,063 lbs 670,650 lbs 7 96,163 lbs 8 125,600 lbs 9 158,963 lbs 10 258,750lbs Pneumatics are faster usually, BUT NEVER as powerful due to the compressible nature of air.

Q:In terms of marine or vessel machineries, I did not understand it clearly, please explain, I need your help.

Auxiliary would be like a pump or power generator, ancilliary would be more like drill press in the mechanics shop, one is needed to service the other, or another example would be the automatic potato peeler in the mess would be ancilliary

Q:I always wondered if nerves sent signals to our muscles, if someone lost a leg or an arm, is it theoretically possible to attach someone's nerves to machinery and control it like a limb?

There are already artificial limbs that work on that principle. Electrodes on the skin pick up signals from muscles in the limb stump or elsewhere on the body, and those are used to drive actuators in the limb. The technology is fairly basic at the moment - just a few movements can be controlled - but it will probably get better. It would be nice if we could attach directly to the nerve bundles in the arm or leg because there are thousands of motor nerves in there. The big problems are infection, stopping the nerve dying, and the body rejecting the electrodes.

Q:Machinery poll: Exactly what job does a piledriver accomplish?
