Bending stress in lever of elliptical cross section Solution

Follow our step by step solution on how to calculate Bending stress in lever of elliptical cross section?

FIRST Step Consider the formula

σ b = \frac{32 \cdot (P \cdot ((l 1) - (d 1)))}{π \cdot b \cdot (a^{2})}

Next Step Substitute values of Variables

∴

σ b = \frac{32 \cdot (294N \cdot ((900mm) - (11.6mm)))}{π \cdot 13mm \cdot ({38mm}^{2})}

Next Step Substitute values of Constants

∴

σ b = \frac{32 \cdot (294N \cdot ((900mm) - (11.6mm)))}{3.1416 \cdot 13mm \cdot ({38mm}^{2})}

Next Step Convert Units

∴

σ b = \frac{32 \cdot (294N \cdot ((0.9m) - (0.0116m)))}{3.1416 \cdot 0.013m \cdot ({0.038m}^{2})}

Next Step Prepare to Evaluate

∴

σ b = \frac{32 \cdot (294 \cdot ((0.9) - (0.0116)))}{3.1416 \cdot 0.013 \cdot ({0.038}^{2})}

Next Step Evaluate

∴

σ b = 141724665.413833Pa

Next Step Convert to Output's Unit

∴

σ b = 141.724665413833N/mm²

LAST Step Rounding Answer

∴

σ b = 141.7247N/mm²
