**Formula:**`σ = F / A`

## Introduction to Tensile Strength Calculator

Tensile strength, often denoted by σ, is a material's resistance to breaking under tension. It is defined as the maximum stress (force per unit area) that a material can withstand while being stretched or pulled before necking, which is when the specimen's cross-section starts to significantly contract.

In this formula, ** F**is the final load applied, in Newtons, that causes fracture, and

**is the original cross-sectional area of the specimen, in square meters.**

*A*## Parameter usage:

`initialArea`

= original cross-sectional area of the specimen`finalLoad`

= final load applied that causes fracture

## Output:

`tensileStrength`

= maximum tensile stress the material can withstand

## Data validation

Both parameters, initialArea and finalLoad, should be numbers greater than zero.

## Summary

This formula calculates the tensile strength of a material given the initial cross-sectional area and the final load at fracture. It helps in material selection and engineering design processes.
