A tangent ogive body has a specific radius for a given length, so how would you determine length if only given the radius?

Looking at the the image below:

$L=\sqrt{r^2-x^2}$

$x=r-\left(\frac{D}{2}\right)$

$L=\sqrt{r^2-\left(r-\left(\frac{D}{2}\right)\right)^2}=\frac{1}{2}\sqrt{-D (D - 4 r)}$

  • $\begingroup$ Also, can you determine the length without knowing the ogive radius, but just the shank diameter? I don't think so. But do let me know. $\endgroup$ – Rajath Pai Nov 12 '19 at 21:01
  • $\begingroup$ If you know any two of the three (Shank Diameter, Ogive Radius, Length) you can calculate the third value. If you only have one value then you can work out the relationship between the final two, but won’t be able get a fixed value. $\endgroup$ – Jonathan R Swift Nov 13 '19 at 8:54
