# Ultimate Tensile Strength

on . Posted in Classical Mechanics

Ultimate tensile strength, abbreviated as UTS, also called tensile strength or ultimate strength, is the maximum stress a material can resist before it starts to elongate.

## Ultimate Tensile Strength formula

$$\large{ UTS = \frac{ F }{ A_c } }$$
Symbol English Metric
$$\large{ UTS }$$ = ultimate tensile stress $$\large{ \frac{lbf}{in^2} }$$   $$\large{ Pa }$$
$$\large{ A_c }$$ = area cross-section of material $$\large{ in^2 }$$ $$\large{ mm^2 }$$
$$\large{ F }$$ = force or maximum load $$\large{ lbf }$$ $$\large{ N }$$
