Helical springs with circular and rectangular section 3

[LCform]

Hello Everybody

I was checking the formulas of helical springs, in the machinery handbook of F.jones, but both the formulas are brought in terms of d and D , diameter, not b and w for the rectangular, actually I am not finding the helical springs calculation for the rectangualr section

would you please guide me ?

desertfox, indeed, I was mistaken and you are right, D should be the mean diameter. Thank you.
