In actual use a machine does...?

This question is a little tricky. Work is the product of FORCE X DISTANCE. Work is energy that has been used or transferred. Work is accomplished when force acts through distance. For example, when a force of 1 pound acts through a distance of 1 foot, 1 foot pound of work is accomplished. \n\nI will have to go with Answer D,  it would be a better chose if the question was about something like motor efficiency. The efficiency of any type of machine is the ratio of the output power to the input power. This ratio is commonly expressed as a percent. Because all machines have some losses, the efficiency will never be 100 percent. \n\nEfficiency = (output/input) X 100\n\nEfficiency = [output / (output + losses)] X 100\n\nor\n\nEfficiency = [(input - losses)/ input] X 100

yes, as long as you use it where it is supposed to be used.

Both. AND how you use it.

Man because they make machine.

No, I use mine often. It's great for making pies and pizzas. By the way - My grandma preferred a broom!!!

No more than a pen or pencil can write.\n\nThe machine is simply a tool, it will be able to only execute the instructions that it has been designed and programmed to execute - nothing more, nothing less.\n\nIt all depends on your interpretation of the word "design". I would say that with the current available technology, no they can't design. They can simply explore the universe of possible designs given to it explicitly or implicitly by a programmer, evaluate each candidate design using a set of metrics given to it by a programmer, and select the best one.\n\nIn my book, this is not design, it is a search.

Yes. I have one and I LOVE IT! Only problem i've ever had is problems shutting it down once or twice. I use it all the time so all in all it's a very good machine.

working. I just use it

If you could, what do you think is the use of it?

I think it is stupid to use machines.\nAs Americans, we are spoiled.\nWe need to be patient once in a while, because time gives you greater accuracy.

A shovel or a backhoe! That's a machine not a 'loose girl'\n\nhttp://www.total-knowledge.com/~willyblues/

Automated Teller Machine\n\nTeller as in bank teller.  Basically it's like a doing a bank transaction w/o a real person, so it's an "Automated Teller".

no i have never landed on my head.\n\n\n\nman you have to be one of the biggest idiots on yahoo answers, i caught your answer to a question \n\n"How can you make the work output of a machine greater than the work input?"\n\nmatthewstonge\nBy definition, a machine outputs more than what is put in. Otherwise, you wouldn't need a machine. \n\n\nLMAOOOOOO

Sure, if you actually use it.

A machine is simply an object that does work. A machine transforms electrical energy into mechanical energy (simple machines excluded).\n\nWhen you think of "work" being done you usually think of some sort of movement occurring.\n\nAn oven is not a machine in that no "work" is being done. An oven just takes electrical energy & transforms it into heat energy.

Any of the machines work,  If you use it.... It's the self discipline that is hard.... I have alot of machines and I have always exercised and I swear by it, but I also found I end up doing more floor exercises then the machines and they seem to work better for me... I get faster results.... So It's up to the individual on buying the machines... Have fun!!!

tools can b used 2 do a lot of works while a equipment is ment for a specific job
