Bending stress in specimen due to bending moment Solution

Follow our step by step solution on how to calculate Bending stress in specimen due to bending moment?

FIRST Step Consider the formula

σ b = \frac{M b \cdot y}{I}

Next Step Substitute values of Variables

∴

σ b = \frac{117000N*mm \cdot 21mm}{44000mm⁴}

Next Step Convert Units

∴

σ b = \frac{117N*m \cdot 0.021m}{4.4E-8m⁴}

Next Step Prepare to Evaluate

∴

σ b = \frac{117 \cdot 0.021}{4.4E-8}

Next Step Evaluate

∴

σ b = 55840909.0909091Pa

Next Step Convert to Output's Unit

∴

σ b = 55.8409090909091N/mm²

LAST Step Rounding Answer

∴

σ b = 55.8409N/mm²
