2.2.3.2 Line parallel to the circle arc init radius
a) Line direction coincides with the direction of the init radius
In this simple case (Figure 2-25) maximum switch radius is equal to the distance between
line L and circle arc init radius. This distance is equal to length of perpendicular
h
dropped
from the circle arc center
O
c
on the line
L.
To define it we can use the same formula
( 2.2.1.1-4).

b) Line direction is opposite to the direction of the init radius
