Length of Kennedy Key given Shear Stress in Key Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

l = \frac{635000N*mm}{\sqrt{2} \cdot 45mm \cdot 5mm \cdot 63.9N/mm²}

Next Step Convert Units

∴

l = \frac{635N*m}{\sqrt{2} \cdot 0.045m \cdot 0.005m \cdot 6.4E+7Pa}

Next Step Prepare to Evaluate

∴

l = \frac{635}{\sqrt{2} \cdot 0.045 \cdot 0.005 \cdot 6.4E+7}

Next Step Evaluate

∴

l = 0.031230242118133m

Next Step Convert to Output's Unit

∴

l = 31.230242118133mm

LAST Step Rounding Answer

∴

l = 31.2302mm
