Substituting the expressions (4.36) and (4.37) into Eq.
(4.5), the boundary of the CRW becomes these two lines:
= Xm
= Y, L
= Zm
= Xm
=Ym + L
= Z,
(4.38)
(4.39)
Furthermore, substituting Eqs. (4.38) and (4.39) into
(4.34) and (4.35) respectively, we obtain the two
corresponding lines of the intersections of the CRSW with
the plane X = constant expressed in X, Y and Z as
Y + L + h (al + bl)2 X2 < 0
-(Y L + h) J(al + bl)2 X2 0
where X is a constant.
The intersection with the plane can
equation which has a form similar to Eq.
Y = -h J(al + bl)2 X2 + (-L)
be expressed in one
(4.33) as
(4.42)
where X is a constant and therefore Eq. (4.42) also
represents two straight lines parallel to the Z axis.
