Construction of the subframe
3.1.2 Section bar dimensions
The table below illustrates the values for the bulk modulus W
x
for C-section bars recommended by IVECO. The indicated W
x
value refers to the real section and allows for the section bar coupling radii (it can be calculated with some approximation by
multiplying by 0.95 the value obtained by considering the section made up of simple rectangles). Bars of different sections can be
used as replacements for the indicated ones, provided that the bulk modulus W
x
and the moment of inertia J
x
of the new C-section
do not features smaller values.
