Hello:
I need advice on how to calculate the coordinates of a vector normal to a parabola section. The parabola is defined by 3 points on a plane: (x1,y1), (x2,y2), (x3,y3). I need to calculate the coordinates of the end point of the normal vector with the starting point (x2,y2) and a precribed magnitude A.
Any help would be greatly appreciated.
Thank you.
David.
Announcing a special workshop to be held at LBL, Berkeley, CA, Aug 1-3, 2007
Here is a hot topic" Overlaps in our knowledge structures " on iMechanica for all of the students!! This belongs to how students iMechanica can be developed or how students can improve it! Please read the comments and let the others know your ideas about this developements. You will find some suggestions there also. With all students ideas collected, there will be a solution to improve current situation for students section. I can say that page and comments are just for students to say how they like their iMechanica to be.
This is a winning entry in the Sci/Terp Video Competition at University of Maryland (UMD).
I am in the industry of Metal cutting, about Truning, milling, drilling... Mainly on solid carbide now. But new CBN, cermetal, ceramic are also great complementarities.
Hope I can join you and discuss about new tec in this field

Reading the article, future role of iMechanica (node/908) posted by Teng (user/10), I am thinking that iMechanica may replace mechanical seminars, lectures conducted by invited mechanicians, in the future.
Academic seminars have several functions: first, to exchange information; second, to build up connections.
Update: An Open Source Review page has been created. Please feel free to leave links, codes and comments on the page.
Dear Mechanicians,
I have seen that there is lot of code sharing among the mechanicians at iMechanica; a search for the word "code" for example produces nearly fifty entries, of which, I believe, at least half of the posts are pointers to codes and their sharing.
I would like to inform you that the Computational Science and Engineering at the University of Illinois at Urbana-Champaign is organizing a workshop on Uncertainty Quantification (UQ) in Computational Science on June 11-12, 2007. There is no registration fee for this workshop !!!
