Both are based on the derivations on the hypotenuse equation.
hypotenuse = Square Root of (oppositeside^2 + adjacentside^2 ).
Just a little visualization from a drawing of the right triangle you are working with.
And a little algebra to shift terms around.
The diagram really helps.
(Hypotenuse - OppositeSide) will indicate 'shrink', for example. This is a visualization.
Just draw increasing angles and notice the 'shrink' is (Hyp-Opp).
Given the angles, you can cosine or sine for the length ratios of the side.
But this is too much for 3:00 AM here.
If you work through it, you will be able to apply it on the job,
when you are hot and sweaty.
On the iNet, google for the Benfield Bender calculations.
Well, on checking my old Greenlee and Benfield manuals,
it is obvious they were written for blue collar guys who use look-up tables.
No equations used in these little manuals, just nice diagrams and tables.
Remember, I'll give you a money back guarantee on this.
But this is too much for 3:00 AM here. Good night. :smile:
