You can tell if a spiral spring pitch is normal by this equation; 0.2*D < p < 0.4*D. However, you can calculate a spiral spring pitch by l = πDn, A = πd2 /4.

To calculate for spiral length, the formula is L = pi*N* (D + d) / 2. This is wherein N = (D - d) / (2*t) is the number of wraps of tape of thickness t on a roll of diameter D (when full) around a core of diameter d.
There are many different types of transition curves but...'Transition Curve', a simple tool used to understand the sorts of issues people might be facing during changeA track transition curve, transition spiral, or spiral easement, is a mathematically calculated Euler spiral fitted between a straight (also known as tangent) and a circular curve on a section of rail track or highway.Website-- http://en.wikipedia.org/wiki/Track_transition_curve--Sillypinkjade------

How do calculate spiral length of Spiral rings
Hi, I may be wrong and correct me if i am. Work is the force applied over a distance: F x d. So to calculate the work of a spiral spring it would be the spring coefficient (usually denoted as "k") times the distance. But you have to remember that the spring force is kxd, so you have to integrate the force over the distance, which will yield the following equation: work is equal to 1/2 the spring constant times the distance squared. W=(1/2) k d2
"Spiral" can be a noun as in, "The spring is in the shape of a spiral", or it can be a verb as in, "He would eventually spiral out of control."
Formula to calculate length of spiral reinforcement in columns
the dia meter of the pile is 750mm the pitch of the sprial rings are 100mm and how to calucualte the lentngth of the rod for the one meter lkength of pile.
It depends on the spiral - there are lots of different ones, with different formulae.
You need a spring scale machine, as commonly found in the aircraft industry.
Rigidity = spiralness + spinginess
