The coordinates of the shear centre are obtained from formulae (5.96):
¯
o
= 23.965m and
y¯
o
=7.5m.
When the location of the shear centre is known, the warping constant can be obtained
from formula (5.97):
The coordinates of the centroid of the layout in the coordinate system whose origin is
in the shear centre are obtained from formula (2.10):
The distance between shear centre
O
and geometrical centre
C
is calculated from
formula (2.9):
with which—in making use of formula (2.11)—the value of the radius of gyration can
be calculated:

Torsion parameter
k
is obtained from formula (3.19):
