Longitudinal Strain Solution

Follow our step by step solution on how to calculate Longitudinal Strain?

FIRST Step Consider the formula

ε longitudinal = \frac{ΔL}{L 0}

Next Step Substitute values of Variables

∴

ε longitudinal = \frac{1100mm}{5000mm}

Next Step Convert Units

∴

ε longitudinal = \frac{1.1m}{5m}

Next Step Prepare to Evaluate

∴

ε longitudinal = \frac{1.1}{5}

LAST Step Evaluate

∴

ε longitudinal = 0.22
