The circle C1 (Figure 2-14) is defined by its init point (80000,0), radius R = 80000, init

angle

α = 0 and a sweep angle β = -135. Line target position (-28284, -28284). The length

of the line segment

ΔL = 28284*2

1/2

= 40000.

The circle C

is defined

the init point (80000,0), radius R = 80000, init angle α = 0

and a sweep angle β = 135.

Circle target position: Xend = 80000*cos(135) = - 56569, Yend = 80000*sin(-135) = -56569.

The length of the line segment

ΔL = [(-56569 + 28284)

* 2]

1/2

= 40000.

Calculate the upper limit of the switch radius by (3.1.3-3): r = (2RΔL – ΔL

)/(2R) =

(2*80000*40000- 40000

)/(160000) =30000
