Mild Steel Rounds

Overview

Engineering reference data for Mild Steel Rounds in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Weight Calculation Formula

The weight of mild steel round bars per unit length can be calculated using the following formula:

$W = 0.0062 \cdot d^2$

Where:

• $W$ is the weight in kilograms per meter (kg/m)
• $d$ is the nominal bar diameter in millimeters (mm)

This formula provides a quick and reliable method for estimating material requirements in structural and mechanical design.
