(2.3.1-20)

where

and C

– Y

From (2.3.1-20),

+ 2C

r + r

(2.3.1-21)

+ C

– 1) + r(2C

+ 2C

+ 2R

) + (C

+ C

– R

) = 0

(2.3.1-22)

but

+ C

= [(X

– X

)

+ (Y

– Y

)

]/R

= 1 (2.3.1-23)

so we get

+ C

= 0 (2.3.1-24)

r = – C

(2.3.1-25)

where

= (X

= (Y

)/R

= X

– X

= Y

– Y

= 2C

+ 2C

+ 2R

= C

+ C

– R

Example 2-30

(Motion Mathematic Lib Samples\Circle to Circle\ Section 2_3\

CircleCircle_Ex_2_30 – www.elmomc.com)

Circle C1 (Figure 2-30) is defined by its radius R1 = 40000, init point P

(-40000, 0), center

coordinates (0,0), init 180

angle and a 90

sweep angle.

Circle C2 is defined by the radius R2 = 100000, init point (0, -40000) center coordinates (-

65000, 35000) and -180

sweep angle.

Coordinates of point P

: X1 = -40000, Y1 = 0;

To get the coordinates of the point P

, use the circle C

equation:

(X + 65000)

+ (Y – 35000)

= 100000

Know that Y2 = 0, for X

use the following equation:

1 2 ... 50 51 52 53 54 55 56 57 58 59 60 ... 71 72
