Bending stress in fiber of curved beam Solution

Follow our step by step solution on how to calculate Bending stress in fiber of curved beam?

FIRST Step Consider the formula

σ b = \frac{M b \cdot y}{A \cdot (e) \cdot (R N - y)}

Next Step Substitute values of Variables

∴

σ b = \frac{985000N*mm \cdot 21mm}{240mm² \cdot (6.5mm) \cdot (78mm - 21mm)}

Next Step Convert Units

∴

σ b = \frac{985N*m \cdot 0.021m}{0.0002m² \cdot (0.0065m) \cdot (0.078m - 0.021m)}

Next Step Prepare to Evaluate

∴

σ b = \frac{985 \cdot 0.021}{0.0002 \cdot (0.0065) \cdot (0.078 - 0.021)}

Next Step Evaluate

∴

σ b = 232624831.309042Pa

Next Step Convert to Output's Unit

∴

σ b = 232.624831309042N/mm²

LAST Step Rounding Answer

∴

σ b = 232.6248N/mm²
