Method of establishing length La
Known e, f, F, and Rmin
F = the maximum lateral float
capability, in feet.
Note: Where the length of flexible transition (La)
computed is greater than the space available, the
length may be reduced by shortening the value of Rmin
in accordance with Section 3, paragraph 3.4.2.
R2f the radius at a point on the
transition curve, 2f distance back from
