Allowable stress for brittle material Solution

Follow our step by step solution on how to calculate Allowable stress for brittle material?

FIRST Step Consider the formula

σ al = \frac{S ut}{f s}

Next Step Substitute values of Variables

∴

σ al = \frac{122N/mm²}{2}

Next Step Convert Units

∴

σ al = \frac{1.2E+8Pa}{2}

Next Step Prepare to Evaluate

∴

σ al = \frac{1.2E+8}{2}

Next Step Evaluate

∴

σ al = 61000000Pa

LAST Step Convert to Output's Unit

∴

σ al = 61N/mm²
