BUILDING & MOUNTING THE STRUCTURES 3-5 E UROCARGO Euro 4/5 3.1.3 Longitudinal section dimensions The table below gives the values for the section modulus W x for C-section longitudinals recommended by IVECO. The indicated W x value refers to the true section and allows for the section radii (this can be calculated with some approximation by multiplying the value obtained when considering the section made up of simple rectangles by 0.95). Longitudinals of different sections can be used instead of those shown provided the section modulus W x and the moment of inertia J x of the new C-section are not lower than those shown in the table.
