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

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

σ b pin = \frac{32 \cdot 100000N*mm}{π \cdot {48mm}^{3}}

Next Step Substitute values of Constants

∴

σ b pin = \frac{32 \cdot 100000N*mm}{3.1416 \cdot {48mm}^{3}}

Next Step Convert Units

∴

σ b pin = \frac{32 \cdot 100N*m}{3.1416 \cdot {0.048m}^{3}}

Next Step Prepare to Evaluate

∴

σ b pin = \frac{32 \cdot 100}{3.1416 \cdot {0.048}^{3}}

Next Step Evaluate

∴

σ b pin = 9210355.5030032Pa

Next Step Convert to Output's Unit

∴

σ b pin = 9.2103555030032N/mm²

LAST Step Rounding Answer

∴

σ b pin = 9.2104N/mm²
