While the form of resistance represents a decisive value for the stress of the material, the moment of inertia is important mainly
for the flexural hardness and for the quota of the bending moment to be taken, depending on the connection used.
Counter-chassis dimension
In case of elastic connection between chassis and counter-chassis the bending moment M
f
must be subdivided proportionately
between chassis and counter-chassis at the moments of inertia of the sections:
