He M Steel Beams

Overview

Engineering reference data for He M Steel Beams 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

HE-M Steel Beam Properties

HE-M (wide flange heavy) steel beams are designed for applications requiring high load-bearing capacity, according to DIN 1025 and Euronorm 53-62 standards.

Unit Conversions

Property	Conversion
Moment of Inertia	$1 \text{ cm}^4 = 10^4 \text{ mm}^4 = 10^{-8} \text{ m}^4 = 0.024 \text{ in}^4$
Section Modulus	$1 \text{ cm}^3 = 10^3 \text{ mm}^3 = 10^{-6} \text{ m}^3 = 0.061 \text{ in}^3$
Area	$1 \text{ cm}^2 = 10^2 \text{ mm}^2 = 10^{-4} \text{ m}^2 = 0.16 \text{ in}^2$
Linear Mass	$1 \text{ kg/m} = 0.67 \text{ lb/ft}$
