Tensile Strength Meaning

Tensile Strength Meaning, Definition, Symbol, Formula and Unit

Today, in this article, I will explain the meaning of Tensile Strength, its definition, Symbol, Formula and Unit. It is a very important topic in engineering. So you should read it thoroughly from start to end with full attention…

Tensile Strength Meaning

When a material is pulled longitudinally from its ends, it develops stress in the material. This is the tensile stress which resists the pulling force. The maximum amount of stress thus developed in the material to resist this longitudinal pulling force before breaking is the Tensile Strength of the material. You can also call Ultimate Tensile Strength (UTS) or simply Ultimate Strength. Tensile Strength, Ultimate Tensile Strength, and Ultimate Strength, all of these terms have the same meaning.

So you can define it in the following way

Tensile Strength Definition

The maximum amount of tensile stress that a material can withstand before breaking is called Tensile Strength.

Tensile Strength Symbol

Tensile strength is represented by UTS or simply TS. Within equation, It is represented by Ftu.

Tensile Strength Formula

You can measure the Tensile Strength of material by calculating or measuring the maximum amount of force applied per unit cross-sectional area. Hence the formula for Tensile Strength is:


Here, UTS = Ultimate Tensile Strength

P = Maximum Axial Pulling Force

A = Cross-Sectional Area

Tensile Strength Unit

As you noticed above, the formula for calculating the UTS uses the maximum force and the cross-sectional area, hence the unit for Tensile Strength will be N/m^2 or you can also use kg/cm^2. So you can also say the tensile strength unit is Pascal (Pa), KPa, MPa, etc..

So this is all about Tensile Strength. I hope you understood all the points. If you have any doubts or need more clarification about any point, mention that in the comments below. And don’t forget to share this post with others also using social media.
