For the Screw dislocation they are parallel, and for the Mixed dislocation each section of the line makes a different angle with the Burgers vector which has a constant magnitude and direction.

Figure caption, The resultant vector of two vectors at right angles If the diagram is drawn to scale like this, the magnitude of the resultant vector can be found by measuring the length of the ...

Angles can be calculated inside semicircles ... Calculating the magnitude of a vector The magnitude of a vector is its size. It can be calculated from the square root of the total of the squares ...

If both strings are the same length then the electrostatic force of each charge on the other is equal in magnitude and directed horizontally ... and electric forces is at an angle determined by the ...
