Permissible Mean Stress for Fluctuating Load Solution

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

FIRST Step Consider the formula

σ m = \frac{S m}{f s}

Next Step Substitute values of Variables

∴

σ m = \frac{100N/mm²}{2}

Next Step Convert Units

∴

σ m = \frac{1E+8Pa}{2}

Next Step Prepare to Evaluate

∴

σ m = \frac{1E+8}{2}

Next Step Evaluate

∴

σ m = 50000000Pa

LAST Step Convert to Output's Unit

∴

σ m = 50N/mm²
