Q:What impairs your ability to operate machinery?

Rage

Q:I have heavy machinery that I want to offer in Vietnam, is ther such a site like ebay or craiglist in Vietnam.

Vietnam is one of the countries listed on Craigslist. I don't know exactly what you're selling but Vietnam isn't in need of heavy equipment.

Q:Do old-fashioned TV sets contain lenses in any part of their machinery?

I dont believe so. I think that they have a really thick glass.

CHECK ON THE AUTOTRADER AND ITS OTHER PUBLICATIONS AND SEE IF THEY CAN HELP YOU. YOU CAN ALSO CALL YOUR LOCAL (DMV) OFFICE AND SEE IF THEY CAN STEER YOU IN THE RIGHT DIRECTION. GOOD LUCK

Q:The cost of machinery which makes an energy from wind...?

may be $1000

Q:Explain why machinery used on a.c supply is usually rated in kVA instead of kW.?

Because most machinery present an inductive load and so has a less-than-unity power factor. The current peak lags the voltage peak in the two waveforms. However, as the current is drawn at a lower voltage (away from the peak), the load current is higher to get the same overall power to the machine. eg. if it took 20% more current to make up for the voltage phase offset, a 1000W load would be taking the same current as a 1200W load at unity power factor. That's the VA rating, it's equivalent to watts at unity power factor.

Q:Dry ice feels like its dry when you hold it. It gives off what looks like a steam from the dryness.

No. It all takes a rather large and expensive machine to make sensible amounts of it. CO2 from a pressure cylinder is just a way to avoid having to buy the machine that put the gas under pressure... somebody still needs to have that gear. It's just not you. You could potentially make very small amounts of dry ice with a very well designed triple peltier cooler. But since dry ice sells for a dollar a bucket, or something like that, why invest time and money to make small amounts of it? And the other person was right... what feels dry about it is your skin freezing. Be careful!

Q:Which prescription drug goes best with Jack Daniels when operating heavy machinery?

Morphine

Q:I know it's a word with it's own meaning, but in 'The monkey's paw' story, Herbert (the son) got killed because he was caught in a machinery. So, what is that machinery anyway?

Jacobs never specifies the exact type of machine but we do know that it was a factory machine. You need to recall that this story was written in 1902. Machines and automation were bery new and the masses were unaccustomed to them. Accordingly, the word machinery had an omnious undertone - perfectly suited for use as an instrument of unexpected, early and grizzly death in a horror story.
