Crippling Stress Solution

Follow our step by step solution on how to calculate Crippling Stress?

FIRST Step Consider the formula

σ crippling = \frac{π^{2} \cdot ε c \cdot r^{2}}{{L e}^{2}}

Next Step Substitute values of Variables

∴

σ crippling = \frac{π^{2} \cdot 10.56MPa \cdot {50mm}^{2}}{{2500mm}^{2}}

Next Step Substitute values of Constants

∴

σ crippling = \frac{{3.1416}^{2} \cdot 10.56MPa \cdot {50mm}^{2}}{{2500mm}^{2}}

Next Step Convert Units

∴

σ crippling = \frac{{3.1416}^{2} \cdot 1.1E+7Pa \cdot {0.05m}^{2}}{{2.5m}^{2}}

Next Step Prepare to Evaluate

∴

σ crippling = \frac{{3.1416}^{2} \cdot 1.1E+7 \cdot {0.05}^{2}}{{2.5}^{2}}

Next Step Evaluate

∴

σ crippling = 41689.2089902015Pa

Next Step Convert to Output's Unit

∴

σ crippling = 0.0416892089902015MPa

LAST Step Rounding Answer

∴

σ crippling = 0.0417MPa
