Mean Stress for Fluctuating Load Solution

Follow our step by step solution on how to calculate Mean Stress for Fluctuating Load?

FIRST Step Consider the formula

σ m = \frac{σ max + σ min}{2}

Next Step Substitute values of Variables

∴

σ m = \frac{180N/mm² + 40N/mm²}{2}

Next Step Convert Units

∴

σ m = \frac{1.8E+8Pa + 4E+7Pa}{2}

Next Step Prepare to Evaluate

∴

σ m = \frac{1.8E+8 + 4E+7}{2}

Next Step Evaluate

∴

σ m = 110000000Pa

LAST Step Convert to Output's Unit

∴

σ m = 110N/mm²
