Allowable Bearing Stress in Local Zone Solution

Follow our step by step solution on how to calculate Allowable Bearing Stress in Local Zone?

FIRST Step Consider the formula

F p = 0.48 \cdot f ci \cdot \sqrt{\frac{A b}{A pun}}

Next Step Substitute values of Variables

∴

F p = 0.48 \cdot 15.5N/mm² \cdot \sqrt{\frac{30mm²}{0.008m²}}

Next Step Convert Units

∴

F p = 0.48 \cdot 15.5MPa \cdot \sqrt{\frac{30mm²}{8000mm²}}

Next Step Prepare to Evaluate

∴

F p = 0.48 \cdot 15.5 \cdot \sqrt{\frac{30}{8000}}

Next Step Evaluate

∴

F p = 455605.092157671Pa

Next Step Convert to Output's Unit

∴

F p = 0.455605092157671MPa

LAST Step Rounding Answer

∴

F p = 0.4556MPa
