Bearing Pressure on Crank Pin Bush Solution

Follow our step by step solution on how to calculate Bearing Pressure on Crank Pin Bush?

FIRST Step Consider the formula

p b = \frac{P c}{d cp \cdot l c}

Next Step Substitute values of Variables

∴

p b = \frac{28800N}{55.8mm \cdot 75.8mm}

Next Step Convert Units

∴

p b = \frac{28800N}{0.0558m \cdot 0.0758m}

Next Step Prepare to Evaluate

∴

p b = \frac{28800}{0.0558 \cdot 0.0758}

Next Step Evaluate

∴

p b = 6809090.13533066Pa

Next Step Convert to Output's Unit

∴

p b = 6.80909013533067N/mm²

LAST Step Rounding Answer

∴

p b = 6.8091N/mm²
