Thickness of Key based on Crushing Stress Solution

Follow our step by step solution on how to calculate Thickness of Key based on Crushing Stress?

FIRST Step Consider the formula

t = \frac{F \cdot 2}{f c \cdot l}

Next Step Substitute values of Variables

∴

t = \frac{236.6N \cdot 2}{14.8N/mm² \cdot 35mm}

Next Step Prepare to Evaluate

∴

t = \frac{236.6 \cdot 2}{14.8 \cdot 35}

Next Step Evaluate

∴

t = 0.000913513513513514m

Next Step Convert to Output's Unit

∴

t = 0.913513513513514mm

LAST Step Rounding Answer

∴

t = 0.9135mm
