Ultimate tensile strength is shortened to tensile strength or ultimate strength. It is defined as the capacity of a material to break under tension. The tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking. Ultimate strength can be defined for liquids as well as solids under certain conditions. Below given the ultimate tensile strength formula to calculate the ultimate strength of any material.

S = F/A

S = Breaking Strength (stress)

F = Force that Caused the Failure

A = Least Cross - sectional Area of the Material

Using the above Ultimate tensile strength formula, the UTS can be calculated by dividing the load or force at break and the original minimum cross-sectional area.
