Stress amplitude (fatigue) Solution

Follow our step by step solution on how to calculate Stress amplitude (fatigue)?

FIRST Step Consider the formula

σ a = \frac{σ r}{2}

Next Step Substitute values of Variables

∴

σ a = \frac{10MPa}{2}

Next Step Convert Units

∴

σ a = \frac{1E+7Pa}{2}

Next Step Prepare to Evaluate

∴

σ a = \frac{1E+7}{2}

Next Step Evaluate

∴

σ a = 5000000Pa

Next Step Convert to Output's Unit

∴

σ a = 5000000N/m²

LAST Step Rounding Answer

∴

σ a = 5E+6N/m²
