Allowable Crushing Strength of Bolt Solution

Follow our step by step solution on how to calculate Allowable Crushing Strength of Bolt?

FIRST Step Consider the formula

f cb = T m \cdot \frac{1}{n \cdot d b \cdot t f} \cdot (\frac{2}{D 1})

Next Step Substitute values of Variables

∴

f cb = 4680N*mm \cdot \frac{1}{3 \cdot 21mm \cdot 100mm} \cdot (\frac{2}{200mm})

Next Step Convert Units

∴

f cb = 4.68N*m \cdot \frac{1}{3 \cdot 0.021m \cdot 0.1m} \cdot (\frac{2}{0.2m})

Next Step Prepare to Evaluate

∴

f cb = 4.68 \cdot \frac{1}{3 \cdot 0.021 \cdot 0.1} \cdot (\frac{2}{0.2})

Next Step Evaluate

∴

f cb = 7428.57142857143Pa

Next Step Convert to Output's Unit

∴

f cb = 0.00742857142857143N/mm²

LAST Step Rounding Answer

∴

f cb = 0.0074N/mm²
