Radial strain for rotating thin disc Solution

Follow our step by step solution on how to calculate Radial strain for rotating thin disc?

FIRST Step Consider the formula

e r = \frac{dr f - dr}{dr}

Next Step Substitute values of Variables

∴

e r = \frac{9mm - 3mm}{3mm}

Next Step Convert Units

∴

e r = \frac{0.009m - 0.003m}{0.003m}

Next Step Prepare to Evaluate

∴

e r = \frac{0.009 - 0.003}{0.003}

LAST Step Evaluate

∴

e r = 2
