a = radius of camshaft
a i = scalar component of w i
A = cam area
A i = component of w i
A G = cubic spline matrices
A xi D yi = cubic spline coefficients at the ith point P i
b i = vector component of w i
c = radius of balancing hole
c = fixed component of follower displacement
c = centroid vector
c 1 = x component of centroid location
c 2 = y component of centroid location
c 3 = z component of centroid location
C = closed cam surface contour
d = component location along axis of rotation
e = follower offset
e = counterweight radius component
e n = unit normal vector
e t = unit tangential vector
e ? = polar circumferential unit vector
e ? = polar radial unit vector
E = 90 degree CCW rotation matrix
f = counterweight centroid location
f s = centrifugal force
F(O,x,y,z) = 3D cam coordinate frame
h ik = polynomial coefficient
h = radial difference vector
I o = cam inertia...
