Often (for better or worse) technical writers assume the reader initiates a topic perusal at an unspecified but assumed beginning. For c, the variable is defined at the beginning of the Chapter (4) on page 4-1 under Columns and Beams (1), Variable Names and Descriptions as c = distance to applied moment (beams).

BEST!

I understood, from reading the AUR, that the variable \(c \) was relevant to the category. However, that variable is completely irrelevant in the second formula above. But because it sets up such a variable, one cannot use the "solve all" and in some cases the result is a bad guess message. Then there is the issue of \( \epsilon \) being clearly explained in the AUR but not appearing the system involving the first formula.
