Bending stress in crank pin of centre crankshaft at TDC position given diameter of crank pin Solution

Follow our step by step solution on how to calculate Bending stress in crank pin of centre crankshaft at TDC position given diameter of crank pin?

FIRST Step Consider the formula

σb pin = \frac{32 \cdot Mb pin}{π \cdot {d pin}^{3}}

Next Step Substitute values of Variables

∴

σb pin = \frac{32 \cdot 206289.5N*mm}{π \cdot {48mm}^{3}}

Next Step Substitute values of Constants

∴

σb pin = \frac{32 \cdot 206289.5N*mm}{3.1416 \cdot {48mm}^{3}}

Next Step Convert Units

∴

σb pin = \frac{32 \cdot 206.2895N*m}{3.1416 \cdot {0.048m}^{3}}

Next Step Prepare to Evaluate

∴

σb pin = \frac{32 \cdot 206.2895}{3.1416 \cdot {0.048}^{3}}

Next Step Evaluate

∴

σb pin = 18999996.3153678Pa

Next Step Convert to Output's Unit

∴

σb pin = 18.9999963153678N/mm²

LAST Step Rounding Answer

∴

σb pin = 19N/mm²
