Compressive Stress in Kennedy Key Solution

Follow our step by step solution on how to calculate Compressive Stress in Kennedy Key?

FIRST Step Consider the formula

σ c = \sqrt{2} \cdot \frac{Mt k}{d s \cdot b k \cdot l}

Next Step Substitute values of Variables

∴

σ c = \sqrt{2} \cdot \frac{635000N*mm}{45mm \cdot 5mm \cdot 35mm}

Next Step Convert Units

∴

σ c = \sqrt{2} \cdot \frac{635N*m}{0.045m \cdot 0.005m \cdot 0.035m}

Next Step Prepare to Evaluate

∴

σ c = \sqrt{2} \cdot \frac{635}{0.045 \cdot 0.005 \cdot 0.035}

Next Step Evaluate

∴

σ c = 114034998.362783Pa

Next Step Convert to Output's Unit

∴

σ c = 114.034998362783N/mm²

LAST Step Rounding Answer

∴

σ c = 114.035N/mm²
