Critical Stress for Cast Iron by NYC code Solution

Follow our step by step solution on how to calculate Critical Stress for Cast Iron by NYC code?

FIRST Step Consider the formula

S w = 9000 - 40 \cdot (\frac{L}{r gyration})

Next Step Substitute values of Variables

∴

S w = 9000 - 40 \cdot (\frac{3000mm}{26mm})

Next Step Convert Units

∴

S w = 9000 - 40 \cdot (\frac{3m}{0.026m})

Next Step Prepare to Evaluate

∴

S w = 9000 - 40 \cdot (\frac{3}{0.026})

Next Step Evaluate

∴

S w = 4384.61538461538Pa

LAST Step Rounding Answer

∴

S w = 4384.6154Pa
