Rather than replacing a broad definition with a narrower one (or attempting a comprehensive set of narrow definitions), it would be better to indicate some usages are specific. I was objecting to declaring the broader definition invalid. Amgine/ talk 02:58, 12 April 2008 (UTC) Reply Agreed. Clearly a machine, and the application of force is not via rigid moving parts but through a flexible moving part. EncycloPetey 01:45, 12 April 2008 (UTC) Reply For example, in rigging, a whip multiplies force in tension through a rope using a single sheave or a bullseye, up to 2x force - friction. We are permitted to write more than one definition if there is more than one common meaning. Consider key policy number 4: "Entries should be written from a neutral point of view, representing all usages fairly and sympathetically." 67.130.129.135 01:31, 12 April 2008 (UTC) Reply That does not mean that the single defintion must cover all usages. In the English language, the word has verifiably been used with reference to devices with but a single part, devices with non-rigid parts, and even non-mechanical devices. Stephen 18:15, 14 March 2008 (UTC) Reply I disagree. Daniel Polansky 17:50, 14 March 2008 (UTC) Reply I like the second one. I wondered about the current definition, so I collected the above options to choose from. Given by Wikipedia as the one describing the common usage of the word, as opposed to scientific defition. Given by Wikipedia as the scientific one.Ī device having rigid moving parts that perform or assist in performing some work. kop 04:08, 22 April 2007 (UTC) Reply Definitions Ī mechanical or electrical device that performs or assists in the performance of human tasks, or is used for amusement (like a pinball machine).Ī mechanical device having rigid moving parts that produces an application of force, usually over a distance, usually to useful effect.Īny device that transmits or modifies energy. a mechanical device having rigid moving parts that produces an application of force, usually over a distance, usually to useful effect.The existing definition is just plain wrong. There is a physics definition of simple machine but that's really another definition. Regardless, electronic devices are only machines in a laxer, and more modern sense. Most electronic devices, cellphones, computers, etc. Entirely electronic devices - electronic devices with no moving parts - are pretty much in their own catagory, they are electronic devices. In other words, electrons are more like fluids than anything else. I understand wanting to call all electronic devices machines, but I don't think they are any more than a hydrolic irrigation system is a machine. Things containing hydrolics are only machines in that they contain rigid parts that the hydrolics move otherwise they're fountains or irrigation systems or some such. An atlatl is not a machine either, although the combination of atlatl and spear might be considered a killing machine. Some things that are not machines: a hammer, a rope, an airfoil, a barometer, a fountain (sans pump), a loudspeaker (although that's on the border).
