  1. Please can you explain me how to use that ecuation in the indicated question (align of the point to the plane)?
  2. Ok I agree, I used the term "quad plane" to explain that type of plane. How the ecuation ax + by + cz = d is used?, let say in the plane the values are (just any value as example): Point A X = 23.5 Y = 10 Z = 20 Point B X = 10.6 Y = 5 Z = 2 Point C X = 35 Y = 20.2 Z = 14 Point D (the one I want to aling to the plane by moving it on X or Y or Z) X = 4 Y = 46 Z = 52.4

  4. Ok is difficult to explain and this board do not allow uploading. You have 3 points in an XYZ enviroment, that create a plane, lets call it 3-plane because it is made of 3 points. You can move any of the points at any place on XYZ and will still have a plane. Now , you have 4 points on an XYZ enviroment, that can create a plane, lets call it quad plane because is made of 4 points. If you move any of the points in XYZ you will get a 3D surface. I indicated that it can create a plane because if the extra point is correctly aligned that will create a planar surface. That extra point can be moved on X or Y or Z to be aligned. Then the info is XYZ values for 3 fixed points that already create a plane, and the value XYZ of the point that need to be aligned to the 3 fixed points to create a planar surface by change its X or Y or Z value.
  5. Quad Plane: a plane made of two triangles (wich is know as plane). You can move a point on a plane to any position and you ever get a plane, let say a planar surface. However on a quad plane you move a point and you get a 3D surface, so the task would be move that point on X or Y or Z to get back a planar surface.
  6. As we know, 3 points define a plane at XYZ, if you add another point then you create a 3D polygon. My question is that if there is a way to align the new point to the others so you can create a quad plane. The info: 3 points with XYZ coordinates (base plane) 1 point with XYZ coordinates wich have to be moved on X or Y or Z to be aligned to base plane and create a quad plane.
  7. It dont show about Al or other metals but thanks.
  8. Ah yes, the range it could be up to 1000 meters, altough the common range will be under 500 meters.
  9. Yes, but oriented on the relationship between weight and speed.
  10. Yes thanks, what about the speed? Im just talking about WW2 tracers altough I dont know how they worked.

  12. I want to determine the kinetic force of WW2 aircraft MGs.
  13. Hello, I want to know the color of the different elements when exposed to hight temperature. By the moment I´m interested on the mix of Mg Al O, and how it can change depending on the % of each element.
