Talk:Cutting
From Wikipedia, the free encyclopedia
Hello, I am a 28 year old religious person who feels like I have to cut. I have never done this before, and have had many councilors.
What should I do.
- i wouldn't do it. i have, it's not worth it.
-
- I've had many friends who have done it and reget it when they stop hurting. Im asking you to Please talk to someone im guessing the councerlors arent helping so try a different outlet and rely on the support of your friends. Some of my mates said it (and this may sound stupid but try it) helpd them to go out side and just run. This is a way of freeing yourself from everything thats going on in your life and taking a break to think about things more rationally. Try to not cut i have been in your position before and its hard to not when your going through it but in the end when everythings better you'll be glad you dont have the scars. Remember it wont help the pain in the long run, know who you are and you'll be alright. (and sometimes it just helps to cry and get it all out)

[edit] Expand
This page needs to be expanded. I'm sure there's more out there on cutting in the engineering sense. For example, rubbing : tribology :: cutting : ? —Ben FrantzDale 00:43, 9 June 2006 (UTC)
[edit] Plasticity
According to the Machinery's Handbook, the very tip of a drill bit plasticly deforms the material being drilled to get it out to the fluites. That makes it sound like at least part of cutting is plastic deformation. Could one cut, say, a steel bar in two with a tool that had a lower ultimate stress but a higher yield stress than the bar? The article as is seems to say no, but I'm inclined to think yes. Suppose you have a bar to cut and a rounded linear indenter (a line as opposed to the usual point) at 90 degrees to the bar. If you indent the bar, it will only deform plastically, but along the groove you've made, the bar is thinner so you are closer to cutting it in half. At least neglecting kerf, it seems like you could extrapolate and repeat the thought experiment until the bar is cut. Thoughts? —Ben FrantzDale 16:25, 5 July 2006 (UTC)
[edit] Self harm
Basically I agree with the reasoning given in the edit [1]. We already have a perfectly good article at self-harm, and this is linked to by Cutting (disambiguation), which in turn is linked to by this article. There is no point covering several different topics in one article when we have already got separate article, with an appropriate disambiguation page.
At best, perhaps we should have a disambiguation link directly to self-harm from here, as there appears to be confusion? But I see no point in having a self-harm section in this article. Mdwh 23:08, 27 August 2006 (UTC)
- Seconded-- the link to self-harm in the disambiguation page is completely buried. I bet there are many more people who are looking for that article instead of, say, information on cutting cards. Alternately, perhaps the disambiguation page should be reworked? Anyway, seeing that this was from half a year ago, I'm going to stick something in-- feel free to change, of course, but there should be an obvious path to the self-harm article from here.

[edit] cutting instrument vs. wedge
The article on "wedges" states that scissors and knives can be used as wedges but are usually cutting instruments instead. This article should help to clarify the difference. It it the direction of force used to separate an object (such as when using a drawing a knife across an object)? If so, scissors still seem to be wedge-like, even though the blades enter an object with a slight rotation. —The preceding unsigned comment was added by 68.222.228.42 (talk) 14:39, 7 March 2007 (UTC).
