Static tensile loading, abbreviated as $$f_t$$, is the mechanical force applied slowly to an object or assembly.

 $$\large{ f_t = \frac{P}{A_c} }$$
 Units English Metric $$\large{ f_t }$$  (Greek symbol sigma) = tensile stress $$\large{\frac{lbf}{in^2}}$$ $$\large{Pa}$$ $$\large{ A_c }$$ = area cross-section $$\large{ ft^2}$$ $$\large{ m^2}$$ $$\large{ P }$$ = load $$\large{ lbf }$$ $$\large{N}$$
