9 GPa.Likewise, another example of reinforcing elements is an assembly of formula 21.28, the construction of which is 3??(0.32+6??0.28)6.2/9.3 SS. This cord has a secant modulus at 0.7% equal to 56 GPa and a maximum tangent modulus equal to 102 GPa, both measured on a curve of tensile stress as a function of elongation determined with a preload of 20 MPa brought down to the cross section of metal
