Mean bending moment in crankpin given bending stress and crankpin diameter Solution

Follow our step by step solution on how to calculate Mean bending moment in crankpin given bending stress and crankpin diameter?

FIRST Step Consider the formula

M b pin = \frac{π \cdot {D cp}^{3} \cdot σ b pin}{32}

Next Step Substitute values of Variables

∴

M b pin = \frac{π \cdot {48mm}^{3} \cdot 9.2104N/mm²}{32}

Next Step Substitute values of Constants

∴

M b pin = \frac{3.1416 \cdot {48mm}^{3} \cdot 9.2104N/mm²}{32}

Next Step Convert Units

∴

M b pin = \frac{3.1416 \cdot {0.048m}^{3} \cdot 9.2E+6Pa}{32}

Next Step Prepare to Evaluate

∴

M b pin = \frac{3.1416 \cdot {0.048}^{3} \cdot 9.2E+6}{32}

Next Step Evaluate

∴

M b pin = 100.000005396065N*m

Next Step Convert to Output's Unit

∴

M b pin = 100000.005396065N*mm

LAST Step Rounding Answer

∴

M b pin = 100000.0054N*mm
