Enter macro images of a machine. A machine is defined as: any mechanical or electrical device that transmits or modifies energy to perform or assist in the performance of human tasks. The catch: Computers, Televisions, phones and cameras are excluded and will be considered off topic... Others will need to guess what machine you took a macro of.
WYSIWYG: There are a lot of entries which are not machines, but tools and instruments... ( 5 years and 2521 days ago )
rbsgrl: I agree with some of the tools, however some of them are "simple machines" as one of the authors pointed out: http://www.crsep.org/PerplexingPairs/SimpleMachinesPart6.Levers1.pdf
It is rather confusing!! ( 5 years and 2521 days ago )
kyricom: A lot of these entries are tools, not machines. WYSIWYG is right. There are 6 "simple machines." They are the pulley, lever, wedge, wheel and axle, a screw, and the inclined plane. ( 5 years and 2520 days ago )
rbsgrl: Then these should be red flagged and let the mod decide. I am not comfortable doing so, for more than one reason. ( 5 years and 2519 days ago )
Toothpick134: Look... Although a hammer for example, may not seem as a machine to us, but in fact if you think about what is in the contest details bit, you soon realise that a human hand transmits kinetic energy to the hammer and therefore the hammer does a job of pinning the nail in to something, I doubt that anyone would be able to preform such action without the use of that hammer..
Same goes for allot of the tools in this contest.. ( 5 years and 2519 days ago )
rbsgrl: And a hammer is also a lever. That's why I think the definition of what most think of when we say machine vs. a simple machine can be rather confusing. ( 5 years and 2519 days ago )
adeincyprus: There are a lot of 'close up', when the contest calls for macros!! ( 5 years and 2517 days ago )
k5683: http://en.wikipedia.org/wiki/Machine#cite_note-AHD-0 ( 5 years and 2517 days ago )
k5683: oops, supposed to be http://en.wikipedia.org/wiki/Machine ( 5 years and 2517 days ago )
kyricom: The contest doesn't say the entries must be one of the 6 simple kinds... but, there is a definite difference between a "machine" and a "tool." ( 5 years and 2517 days ago )
