Shear Stress in Kennedy Key Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

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

Next Step Convert Units

∴

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

Next Step Prepare to Evaluate

∴

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

Next Step Evaluate

∴

𝜏 = 57017499.1813914Pa

Next Step Convert to Output's Unit

∴

𝜏 = 57.0174991813915N/mm²

LAST Step Rounding Answer

∴

𝜏 = 57.0175N/mm²
