F1 RESULT(1) Not Used Not Used Not Used
F2 RESULT(2) Left Wheel Front View Swing Arm Length mm The distance between the left wheel center and the left wheel center front view instant center. It is calculated using the following equations:
Orientation A:

dy = C(2,3)-C(2,9)

dz = C(3,3)-C(3,9)

dtheta = C(4,3)-C(4,9)

length = sqrt(dy^2+dz^2)/abs(dtheta)

Orientation B:

dy = -C(2,3)+C(2,9)

dz = C(3,3)-C(3,9)

dtheta = -C(4,3)+C(4,9)

length = sqrt(dy^2+dz^2)/abs(dtheta)

F3 RESULT(3) Right Wheel Front View Swing Arm Length mm The distance between the right wheel center and the right wheel center front view instant center. It is calculated using the following equations:
Orientation A:

dy = C(8,9)-C(8,3)

dz = C(9,9)-C(9,3)

dtheta = C(10,9)-C(10,3)

length = sqrt(dy^2+dz^2)/abs(dtheta)

Orientation B:

dy = -C(8,9)+C(8,3)

dz = C(9,9)-C(9,3)

dtheta = -C(10,9)+C(10,3)

length = sqrt(dy^2+dz^2)/abs(dtheta)

F4 RESULT(4) Average Front View Swing Arm Length mm The mean of the left and right wheel front view swing arm length.
F5 RESULT(5) Not Used Not Used Not Used
F6 RESULT(6) Left Wheel Front View Swing Arm Angle deg The front view angle between horizontal and the line connecting the left wheel center and the left wheel center front view instant center. It is calculated using the following equations:
Orientation A:

dy = C(2,3)-C(2,9)

dz = C(3,3) - C(3,9)

angle = -atan(dy/dz)*rtod

Orientation B:

dy = -C(2,3)+C(2,9)

dz = C(3,3) - C(3,9)

angle = -atan(dy/dz)*rtod

F7 RESULT(7) Right Wheel Front View Swing Arm Angle deg The front view angle between horizontal and the line connecting the right wheel center and the right wheel center front view instant center. It is calculated using the following equations:
Orientation A:

dy = C(8,9)-C(8,3)

dz = C(9,9) - C(9,3)

angle = atan(dy/dz)*rtod

Orientation B:

dy = -C(8,9)+C(8,3)

dz = C(9,9) - C(9,3)

angle = atan(dy/dz)*rtod

F8 RESULT(8) Average Front View Swing Arm Angle deg The mean of the left and right wheel front view swing arm angle.
