Bending stress in centre crankshaft at TDC position below flywheel given shaft diameter Solution

Follow our step by step solution on how to calculate Bending stress in centre crankshaft at TDC position below flywheel given shaft diameter?

FIRST Step Consider the formula

σ bf = \frac{32 \cdot M br}{π \cdot {d s}^{3}}

Next Step Substitute values of Variables

∴

σ bf = \frac{32 \cdot 100.45N*m}{π \cdot {31.74mm}^{3}}

Next Step Substitute values of Constants

∴

σ bf = \frac{32 \cdot 100.45N*m}{3.1416 \cdot {31.74mm}^{3}}

Next Step Convert Units

∴

σ bf = \frac{32 \cdot 100.45N*m}{3.1416 \cdot {0.0317m}^{3}}

Next Step Prepare to Evaluate

∴

σ bf = \frac{32 \cdot 100.45}{3.1416 \cdot {0.0317}^{3}}

Next Step Evaluate

∴

σ bf = 31998474.8875089Pa

Next Step Convert to Output's Unit

∴

σ bf = 31.9984748875089N/mm²

LAST Step Rounding Answer

∴

σ bf = 31.9985N/mm²
