Elongation Calculator

Formula

The formula to calculate the elongation (E) is:

\[ E = L₀ \times \varepsilon \]

Where:

\( E \) is the elongation (units)
\( L₀ \) is the original length of the material (units)
\( \varepsilon \) is the strain (no units), which is the ratio of the change in length to the original length

Elongation: A measure of how much a material can stretch or elongate under tensile stress before it breaks. It indicates the ductility of the material and is typically expressed as a percentage of the original length after the material has been pulled apart.

Let's say the original length (L₀) is 100 units and the strain (ε) is 0.05. Using the formula:

\[ E = 100 \times 0.05 \]

We get:

\[ E = 5 \, \text{units} \]

So, the elongation is 5 units.
