Engineering strain Solution

Follow our step by step solution on how to calculate Engineering strain?

FIRST Step Consider the formula

𝜀 = \frac{l i - L 0}{L 0}

Next Step Substitute values of Variables

∴

𝜀 = \frac{2cm - 5000mm}{5000mm}

Next Step Convert Units

∴

𝜀 = \frac{0.02m - 5m}{5m}

Next Step Prepare to Evaluate

∴

𝜀 = \frac{0.02 - 5}{5}

LAST Step Evaluate

∴

𝜀 = -0.996
