Ultimate strength can be defined for liquids as well as solids under certain conditions. This uses the equations from ANSI B1 1-1974 and B18.3.1-1978 which calculates the area carrying the tensile load from the mean of the pitch diameter and the minor diameter.

• P= Tensile load– a direct measurement of clamp load (lbs., N) • St= Tensile strength– a generic measurement of the material’s strength (psi, MPa). Tensile Stress Area of Bolt, often represented by At, is a physical quantity used to measure the crirical stress area or the mimimum area of threaded section of a bolt. } else if (load == 'sae8') {
