Discuss The Viv Lab Rigid Arm

@rauliruegas 

You have stripped all context from my original quote which was about the requirement of both overhang and offset to get two null points.   Without overhang which requires an effective length to calculate the two null points cannot exist.

@intactaudio : " was about the requirement of both overhang and offset to get two null points. Without overhang which requires an effective length to calculate the two null points cannot exist. "

That could be for you but not for Löfgren him self that was who specified that formula, it was not me and certainly not you but LÖFGREN.

As a fact to calculate overhang the most inner/outer values are necessary in the Löfgren A . Effective length is necessary for the overhang calculation but not for null points calculations. Again it’s not me but Löfgren in his A alignment.

@rauliruegas 

specifying a formula and not understanding its relationship to the discussion at hand serves little good.  I doubt Løfgren would suggest it possible to get two null points without the addition of overhang no matter how much you point him to his math.

@intactaudio : Your doubt but not Löfgren, Baerwald or Stevenson in their respective A and B alignments.

" and not understanding its relationship to the discussion at hand serves little good. "

Obviously speaking by your self understanding.

Btw, Löfgren certainly not " suggest " HE STATED/SPECIFIED it in that formula that comes from HIM.

Can you understand that HIM?

R.

@rauliruegas 

then please kindly explain to @dover how to use the null point formula you presented to set the two null points for the arm with zero offset.
