Spiral Curve Tangent Distance Calculator

Posted by Dinesh on

This calculator calculates the tangent distance to any point on the spiral (y) using length of spiral from tangent to any point (l), length of spiral (ls), radius of simple curve (r) values.

Spiral Curve Tangent Distance Calculation

Formula:

Y = L − { L5 / ( 40×R²×Ls²) }

Where,
Y - Tangent distance to any point on the spiral
L - Length of spiral from tangent to any point
Ls - Length of spiral
R - Radius of Simple Curve
