Hoop stress Solution

Follow our step by step solution on how to calculate Hoop stress?

FIRST Step Consider the formula

σ θ = \frac{P i \cdot D i}{2 \cdot t}

Next Step Substitute values of Variables

∴

σ θ = \frac{0.053MPa \cdot 50mm}{2 \cdot 525mm}

Next Step Convert Units

∴

σ θ = \frac{53000Pa \cdot 0.05m}{2 \cdot 0.525m}

Next Step Prepare to Evaluate

∴

σ θ = \frac{53000 \cdot 0.05}{2 \cdot 0.525}

Next Step Evaluate

∴

σ θ = 2523.80952380952Pa

Next Step Convert to Output's Unit

∴

σ θ = 2523.80952380952N/m²

LAST Step Rounding Answer

∴

σ θ = 2523.8095N/m²
